SOSCleanroom Technical Vault | Cleanroom Glove Engineering A detailed engineering and purchasing guide to particle cleanliness, nonvolatile residue, ESD, strength, glove qualification and the true cost of an ISO 4 alternative. The CT International NWCP 200 Series is the closest CTI alternative to Hourglass HandPRO 9300 in the information reviewed. Both are non-sterile, white, 12-inch-class nitrile cleanroom gloves marketed for Class 10 / ISO 4-compatible environments. CTI's NWCP series is DI-water-washed, antistatic, textured at the fingertips and double-bagged. CTI supplied SOSCleanroom with comparison data indicating a particle-count threshold below 400 for NWCP 200 versus Hourglass's published value below 650 particles/cm². CTI also reported a nonvolatile-residue (NVR) threshold below 2.5 µg/cm² versus Hourglass's published threshold below 5.0 µg/cm². These are specification ceilings, not actual measured results from matched production lots. Crucially, the comparison cannot yet be treated as a validated like-for-like cleanliness test: CTI's particle units and full test conditions have not been independently verified. SOSCleanroom's selection verdict The buying case is straightforward: the same stated ISO 4 application class, a verified $266.00/1,000-glove SOSCleanroom listing, an established DI-water-washed CTI manufacturing route and CTI-reported tighter cleanliness acceptance limits. That makes NWCP 200 a compelling first option for cost reduction and second-source programs. What we are not claiming: CTI has not yet provided a method-matched head-to-head study demonstrating fewer particles per unit area, lower observed residue in every lot, superior chemical protection or higher tensile strength. Approve the alternative only after the required product-specific evaluation. Both NWCP 200 and HandPRO 9300 are positioned for Class 10 / ISO 4 applications. CTI-supplied NWCP figure; Hourglass publishes <650 particles/cm² (0.5–20 µm). Methods and units require alignment. µg/cm² for NWCP versus Hourglass's published <5.0 µg/cm². Extraction methods must be compared. SOSCleanroom selection perspective: NWCP 200 is the appropriate CTI candidate for a customer seeking an ISO 4 alternative to HandPRO 9300. CTI NCP 200 (ISO 5 / Class 100) is a separate option for applications qualified to a different cleanliness profile. Price check date: . This table is a dated snapshot of advertised prices, not live competitor pricing or a guaranteed quote. For purchasers comparing ISO 4 / Class 10, non-sterile, 12-inch nitrile gloves, case cost matters alongside cleanliness qualification. At the time of this review, SOSCleanroom displayed the CT International NWCP Series at $266.00 per case of 1,000 gloves, a lower published case price than several listed HandPRO 9300 distributors. SOSCleanroom | CTI NWCP Series Per 1,000 gloves • $0.266 per glove • published Nov. 6, 2026 Listed HandPRO 9300 case prices checked Four published 1,000-glove case listings; actual prices vary by distributor, account, size and quantity. Comparison of case listings, in US dollars. Shorter bars represent lower advertised prices in this particular sample of retailers. Scope: These five values are advertised prices normalized to one 1,000-glove case, before taxes, freight, negotiated terms and other charges. Vendor promotions and quantity discounts may change the ranking. Prices checked . Why consider CTI? In the published case listings above, NWCP provides a lower entry price while offering the same nominal ISO 4 / Class 10 cleanroom positioning and supplier-reported lower particle/NVR acceptance ceilings. The latter are specifications awaiting method-equivalence confirmation, not proof of superior results across manufacturing lots. Pricing transparency: These prices are a historical comparison, not a universal lowest-price guarantee. For example, R.S. Hughes displayed HandPRO 9300 at $25.61 per bag of 100 during this review (a theoretical $256.10 for ten bags), which is below SOS's listed case price before any shipping/quantity considerations. Midwest also advertised quantity discounts. Bag prices, case prices, discounts and fulfillment terms are not automatically interchangeable. For current NWCP pricing, always check the live SOSCleanroom product page or request a written volume quote. Tell our team which HandPRO size you use, the intended CTI glove size, your estimated monthly or annual case usage, and the contamination-control requirements you need documented. Ask about NWCP evaluation samples and quantity-based special pricing. Sample availability and quotations are subject to confirmation. Or call 800-443-7101 and reference CT International NWCP Series / HandPRO 9300 replacement evaluation. Displayed prices and availability can change without notice; visiting a source after the review date may show a different amount. Price comparison excludes contract terms, promotions, tax, freight and any non-comparable purchase-unit conditions. No competitor offers are endorsed by SOSCleanroom. Volume buyers should calculate spend at the same usable glove quantity, rather than comparing a single bag price with a case price. For the four HandPRO case listings reviewed, SOSCleanroom's NWCP price equates to $0.266 per glove. The Midwest HandPRO case listing equates to approximately $0.286 per glove; Lab Depot is $0.305, Krackeler $0.390 and Fisher's Large listing $0.4775. Illustrative arithmetic using November 6, 2026 displayed case prices, assuming unchanged single-case prices for all quantities. These are not current volume quotations or guaranteed savings. Actual discounts, case-mix, freight, taxes and order terms may materially change results. A trial may entail separate qualification costs. Purchasing recommendation: Bring your annual case forecast, incumbent HandPRO part numbers and target delivered price to SOSCleanroom. Ask for a written special quantity price, evaluate NWCP samples in your process, and compare delivered, qualified cost per usable glove—not just a list price. Cleanroom glove particle specifications describe contamination associated with the glove, rather than airborne particles in the room. The charts below visualize the numerical specification ceilings supplied for this comparison. They do not represent actual measured particles on gloves, field defect rates or independently normalized comparison data. Lower numeric thresholds can indicate a more restrictive specification only if counting ranges, units and methods are equivalent. Chart interpretation: Bar length reflects only the reported numerical ceiling relative to the largest shown (950). Hourglass defines its result as particles/cm² for 0.5–20 µm. CTI's supplied sheet identifies particles ≥0.5 µm but does not establish the same unit denominator, upper size limit, extraction procedure or counting method. The bars must not be interpreted as proof that NWCP releases fewer particles or is 38% cleaner. *CTI numbers are supplier-reported and pending a product-specific, method-qualified specification sheet. Why this matters: In wafer handling, optical coating, sensor assembly and precision component packaging, a glove can introduce particles through physical contact, handling, abrasion or packaging. A lower verified glove-specific particle limit may help a process engineer establish a cleanliness budget, but actual suitability requires process qualification. Units: µg/cm² (micrograms per square centimeter). Lower limits can be relevant to surface-contamination-sensitive processes. Chart interpretation: CTI's submitted NWCP NVR ceiling is numerically half the Hourglass published ceiling. This is a difference between reported acceptance thresholds, not proof of half the residue in production gloves. Extraction solvents, temperature, time, surface-area calculations and analytical methods must be reconciled before comparing results directly. *CTI values are supplier-provided. Reading the table: "Published" means verified on the linked manufacturer's product page or HandPRO specification; "CTI supplied" means furnished in the comparison provided to SOSCleanroom, but not independently confirmed on the public NWCP product page. * CTI-provided comparison information; current independent, product-specific substantiation has not been reviewed for this value. CTI's published general glove thickness is 5 ±1 mil (roughly 0.127 ±0.025 mm) without identifying the measurement point. Accordingly the supplier-provided 0.18 mm fingertip result is presented as provisional, not as a confirmed physical advantage. ISO 14644-1 addresses airborne particle concentrations in the room, not particles extracted from glove surfaces. This is a separate measurement system from Chart 1 above. NWCP and HandPRO are positioned for ISO 4, while CTI's NCP Series is positioned for ISO 5. Maximum airborne particle concentration, particles per cubic meter (particles/m³). Educational distinction: The ISO 4 airborne concentration limit at this size threshold is one-tenth the ISO 5 limit. These values describe air cleanliness classification; they are not permissible particle counts on a glove. A glove described as "ISO 4 compatible" still needs product-specific cleanliness and use qualification. Surface contact, donning, packaging transfer and glove abrasion may introduce contamination to wafers, optics, small assemblies and clean fixtures. Particle specifications can support material-selection decisions only when the analytical basis is clearly defined. Nonvolatile residue represents material remaining after a defined extraction and evaporation process. Total NVR does not reveal the chemical identity of any residue, so sensitive applications may require ionic and organic analysis as well. Important: A tighter specification ceiling is not a measured reduction in process defectivity or a guarantee of cleaner gloves in every lot. For a high-value application, request current certificates of analysis and, where appropriate, perform application-specific qualification. Air cleanliness is just one part of contamination control. A cleanroom can satisfy its airborne classification while a hand-contact step transfers removable particles or residues to a product. For high-value wafers, precision optics, sensors or bonding interfaces, contact materials must be qualified independently of the room. A glove arrives with a packaging and lot-specific contamination profile. Unpacking, stretching, friction or contact with nonqualified surfaces may mobilize material. Particles, ions or organic residue may transfer when the glove touches tools or product surfaces. Depending on the process, contamination may affect yield, adhesion, visual quality or test confidence. CTI publicly identifies NWCP as DI-water-washed and double-bagged. DI-water washing is a meaningful processing detail because it is intended to control certain removable contamination; double-bagging supports staged material transfer from receiving to a cleaner production zone. Neither feature alone establishes an allowable particle or ionic contamination level—the product must still be measured and handled properly. The key engineering question: Will NWCP 200 reduce contamination risk in your process while satisfying operator protection requirements at a lower qualified purchase cost? A method-matched sample study is the appropriate way to answer it. CTI's comparison lists a nominal NWCP fingertip thickness of 0.18 ±0.01 mm versus Hourglass's typical 0.14–0.16 mm. CTI's public NWCP page, however, lists a generic thickness of 5 ±1 mil and does not identify the point of measurement. Therefore we recommend confirming a current CTI dimension drawing or controlled data sheet before calling the NWCP a thicker-finger glove. Thickness does not establish puncture resistance, durability, chemical permeation resistance or tactile sensitivity by itself. Glove formulation, geometry, mechanical data and actual use all matter. Hourglass publishes typical before-aging tensile results of 23.8–28.0 MPa alongside its minimum of 14 MPa; CTI's public NWCP page states 14 MPa without a matching distribution of typical results. A superiority claim for NWCP tensile strength is not supported by the reviewed public data. The CTI comparison supplied to SOSCleanroom lists <400 particles ≥0.5 µm and <2.5 µg/cm² NVR for NWCP 200. Hourglass publishes <650 particles/cm² at 0.5–20 µm and <5.0 µg/cm² NVR. The figures suggest an attractive CTI acceptance profile, but only the Hourglass document clearly states the particle surface-area denominator and counting interval in the information currently reviewed. For instance, a result reported as particles per glove cannot be directly compared with particles per cm². Even two area-normalized results may differ if one method counts particles above 0.5 µm without an upper cutoff while another is restricted to 0.5–20 µm. Agitation, extraction water, recovery efficiency, sampling, blank correction and instrumentation also influence the apparent value. Nonvolatile residue is the material left after a defined extraction solvent is collected and evaporated. It may represent removable organic or inorganic compounds, but its total mass does not reveal which compounds are present. A lower NVR ceiling is relevant when a process is sensitive to thin-film contamination, coatings, adhesive bonds or trace analytical interference; it is not a universal guarantee of better chemical compatibility. IEST-RP-CC005.4 is a recognized recommended practice for testing cleanroom gloves and finger cots. CTI's public product listing references the earlier IES-RP-CC-005.2 testing method, while the Hourglass PDF references IEST-RP-CC005.4. This is an additional reason to request full method details rather than assume equivalence from the common IEST family name. Hourglass publishes HandPRO 9300 as accelerator-free and sulfur-free. CTI supplied those same descriptions for NWCP 200, although they are not stated on the public CTI NWCP product page reviewed for this article. For processes sensitive to particular additives or operator skin sensitization, request the current CTI formulation declaration. Both manufacturers also describe their products using antistatic or static-dissipative language. Those descriptions are not equivalent to a verified surface-resistance or charge-decay result under the customer's exact test conditions. Facilities with ESD control requirements should request numerical resistance values, test method, test humidity and conditions of use. Chemical protection is a separate qualification. Nitrile construction and cleanroom compatibility do not by themselves demonstrate protection against any specified solvent, chemical splash or hazardous drug. Select chemical PPE using chemical-specific permeation, degradation and applicable certification data. Hourglass explicitly specifies an AQL of 1.5 for freedom from holes in its HandPRO 9300 product sheet. CTI describes NWCP as leak-tested, but the public NWCP listing reviewed does not supply a directly comparable holes-AQL value. AQL is a sampling-based quality acceptance parameter; it is not a prediction that exactly 1.5% of gloves in every shipment contain holes. Request a current CTI sampling and defect specification where barrier integrity is a critical purchasing requirement. CTI describes NWCP as antistatic; Hourglass describes HandPRO 9300 as static dissipative in use. Neither description, by itself, establishes a quantitative resistance or charge-decay requirement for an electronics assembly line. A meaningful comparison requires the test method, humidity, conditioning, instrument settings and numerical results. Ask whether performance is measured with the glove worn, and whether glove fit and contact surfaces affect the observed result. Hourglass publishes EN ISO 374-related chemical/biological PPE information and markets HandPRO 9300 as a low-endotoxin glove. The CTI public NWCP product page reviewed does not show equivalent chemical-permeation data or a numerical endotoxin specification. These are not proven CTI advantages; if your process requires either, obtain documentation and approval before substitution. A glove compatible with ISO 4 air cleanliness is not necessarily suitable for aseptic compounding, cytotoxic drug exposure or a specified solvent. When would Hourglass remain the rational choice? When a process is already validated around a documented HandPRO property that CTI has not yet substantiated—such as a particular chemical PPE certification, low-endotoxin test, tensile behavior or hole-AQL requirement—and the cost or risk of requalification outweighs the quoted savings. This is why we encourage a documented NWCP trial, not an unqualified one-for-one substitution. Potential applications include qualified wafer-carrier handling, component assembly and inspection operations that require low particle-transfer and low-residue materials. Precision coating, lens or photonic component processes may benefit from careful controls around glove-transferable particles and residues. Where non-sterile gloves are permissible, evaluate glove cleanliness against documented product-contact and bioburden-control requirements. Assess glove extractables, ionic contaminants and sample compatibility before handling trace-analysis samples or sensitive materials. Even when a glove is suitable for a cleanroom classification, it may not be suitable for every operation in that cleanroom. For applications requiring sterile gloves, select a separately qualified sterile glove. Purchasing perspective: Compare more than case price. Consider accepted-lot cleanliness, handling efficiency, packaging configuration, glove consumption, qualification effort and the cost of process contamination. A glove cannot perform to its intended cleanliness profile if contaminated during unpacking, donning or handling. The following controls should be adapted to the facility's validated gowning and material-transfer SOPs. Choose NWCP 200 for evaluation against HandPRO 9300: both are positioned for ISO 4 / Class 10 environments. Size range difference: Hourglass lists XS–XXL, while CTI NWCP is listed S–XXL; customers wearing XS need a separately qualified size solution. Consider NCP 200 separately: CTI markets the NCP 200 Series for ISO 5 / Class 100 environments, which may be appropriate when it meets the process's required cleanliness profile. DI-water-washed, non-sterile nitrile, 12-inch length, textured fingertips, antistatic and double-bagged; listed by SOSCleanroom in Small through XX-Large. Non-sterile nitrile alternative positioned for Class 100 / ISO 5 environments; determine suitability from the facility's actual requirements. Yes, both manufacturers position these gloves for ISO 4 / Class 10 compatible use. A process-specific substitution still needs qualification and documented acceptance. No. The 400 figure is CTI-supplied without independently verified normalization and test details, while the Hourglass figure is <650 particles/cm² in the 0.5–20 µm interval. The comparison is a useful lead for qualification, not a demonstrated head-to-head result. The CTI-supplied acceptance ceiling of <2.5 µg/cm² is numerically half Hourglass's published <5.0 µg/cm² ceiling. This does not mean actual measured residue is necessarily half, and methods must be reviewed. No. NWCP 200 and HandPRO 9300 are both non-sterile products. Sterility is a distinct property from particle cleanliness or ISO room compatibility. Not automatically. Thickness is only one variable. Puncture, tensile, chemical and comfort performance need appropriate, comparable test data. CTI's supplier-provided fingertip thickness also needs reconciliation with its public generic thickness specification.
