Customer SOP note (read before standardizing)
This Technical Vault entry provides practical, technician-focused guidance and selection context. It is not your facility SOP and it does not replace validation, environmental monitoring strategy, or quality-system requirements.
Always follow your site procedures, training, and change control. Confirm glove compatibility with your chemicals and surfaces, and verify suitability for your risk-based contamination control strategy (CCS).
Where sterile handling is required, use only products specifically labeled and qualified for sterile presentation per your validated process.
1) Practical solutions in a critical environment
In ISO Class 5 (Class 100) work, glove choice is not about “hand protection” alone. Gloves become a primary contamination-control interface: they touch tools, fixtures, parts, packaging, and sometimes critical surfaces.
TN300W is positioned as a controlled-environment nitrile glove with published particle, ionic extractables and nonvolatile residue (NVR) limits, plus stated electrostatic discharge (ESD) properties for humidity-controlled operations.
In U.S. regulated workflows, teams typically align glove programs to FDA cGMP expectations and facility contamination-control strategy; EU GMP Annex 1 can be used as a global benchmark for CCS rigor and handling discipline without implying it is a U.S. legal requirement.
2) What are these gloves used for
TN300W cleanroom nitrile gloves are used for contamination-controlled handling and light chemical splash/intermittent-contact tasks where teams want nitrile (to reduce natural rubber protein allergy concerns) with double-bagged cleanroom packaging and published cleanliness/ESD performance attributes.
- Component handling in ISO Class 5 cleanrooms (microelectronics, optics, medical device assembly support, controlled manufacturing).
- Bench operations requiring controlled particulate and extractables background (process-dependent).
- Humidity-controlled work areas where static attraction is a yield risk (ESD performance is stated at 50–60% RH).
3) Why should customers consider these gloves
- ISO Class 5 positioning: Listed as Class M3.5 / Class 100 / ISO Class 5 for controlled environments.
- Powder-free nitrile: Helps reduce powder-related contamination variables while avoiding natural rubber protein exposure pathways common to latex programs.
- Published cleanliness limits: Stated particle level, ionic extractables and NVR limits support more defensible baseline expectations versus unqualified disposables.
- Stated ESD behavior: Surface resistivity and static decay targets are provided for a defined humidity band (verify in your environment and with your grounding strategy).
- Cleanroom packaging discipline: Double-bagged and poly-sealed bag packaging supports controlled introduction to cleaner areas.
- Service and continuity: SOSCleanroom focuses on best-in-class consumables for critical environments and does not compromise on quality “to save cost,” because yield and contamination risk are the real cost drivers.
4) Materials and construction
TN300W is described as a 100% nitrile, powder-free, ambidextrous glove with microtextured fingertips and a beaded cuff. The glove is supplied in white and is packaged for controlled environments (double-bagged).
For cleanroom operations, the practical “construction” story is less about cosmetic features and more about what the glove does under use: maintaining a stable surface, limiting particulate and extractables release, and supporting repeatable don/doff without tearing or shedding.

6) Specifications in context
The key performance drivers for TN300W in ISO Class 5 work are repeatable glove integrity (donning durability, tear resistance in use), controlled releasables (particles, ions, NVR) and static control behavior where attraction to parts or tooling is a defect mode.
The 9.5" length supports routine cuff coverage for many benches; if your gowning program requires more forearm coverage or you are reaching into equipment, a longer-cuff glove may reduce exposed-sleeve risk.
The 5 mil thickness is a classic “dexterity vs. robustness” middle ground: thick enough to resist puncture better than ultra-thin exam gloves, while still supporting tactile tasks. Confirm that thickness does not compromise fine handling in your process.

8) Packaging, handling, sterility, traceability
- Pack configuration: 100 gloves per poly-sealed cleanroom bag; 10 bags per case (1,000 gloves/case).
- Clean introduction discipline: Double-bagged packaging supports staged entry (de-bag in the appropriate gowning/material transfer zone per your CCS).
- Sterility: Not stated for this product listing. If sterile presentation is required for your workflow, source a glove explicitly labeled sterile and qualify it through your change-control process.
- Traceability/documentation: Certificate of Conformance is stated as available on request (retain lot-level records consistent with your investigation and deviation workflow).
9) Best-practice use in the cleanroom
The glove can meet its published cleanliness targets and still fail your process if technique drifts. Use these operator-level practices to reduce excursions and rework:
- Donning control: Don with slow, controlled motion; avoid “snapping” the cuff which can aerosolize particles and shed from sleeves. If a glove brushes non-controlled surfaces, discard it.
- Touch discipline: Define “clean touch zones” vs. “dirty touch zones” (door handles, carts, keyboards). Change gloves when crossing zones; do not re-enter critical work with suspect contact history.
- ESD behavior is humidity dependent: The stated ESD properties are referenced at 50–60% RH. If your room runs drier, validate actual behavior in your environment and ensure your grounding strategy (wrist straps, flooring, footwear, benches) is coherent.
- Chemical compatibility: Nitrile provides broad chemical resistance, but compatibility is chemistry- and time-dependent. Use the chemical resistance chart as a screening tool, then validate for your specific solvent mix, concentration, and exposure time.
- Pair with the right low-linting wipers/swabs: In ISO 5 areas, use wipers and swabs with stated ISO-class positioning and controlled packaging so the glove does not become the “clean” variable paired with a “dirty” consumable.

https://www.soscleanroom.com/product/swabs/texwipe-tx714a-large-alpha-polyester-cleanroom-swab/
Note: “Low-linting” outcomes depend on surface condition and technique. No wiper or swab is truly lint-free across all substrates, edge conditions and stroke methods.
10) Common failure modes
- Micro-tears and pinholes: Often caused by aggressive donning, jewelry, sharp fixture edges or tool knurling. Establish discard rules and consider fingertip protection strategies for high-snags tasks.
- ESD drift: If humidity falls outside the stated range, static control performance may change. Monitor room RH and confirm ESD behavior in your real configuration.
- Cross-contamination through touch history: The glove can be “clean” out of the bag and still become the contamination vector through uncontrolled contacts (carts, boxes, keyboards, doorknobs).
- Chemical mismatch: Nitrile is broad-resistance, not universal. Compatibility depends on concentration and exposure time; validate especially for ketones, chlorinated solvents, or strong oxidizers per your safety program.
- Packaging handling shortcuts: Opening inner packaging in the wrong zone or staging open bags at the bench increases unknown exposure. Use a defined staging method consistent with your CCS.
11) Closest competitors
When comparing ISO Class 5 nitrile gloves, treat it as a system decision: cleanliness data, packaging controls, ESD behavior, and documentation discipline matter as much as “fit and feel.”
Closest functional peers typically include:
- Ansell cleanroom nitrile programs: Often selected when teams want a best-in-class brand line with strong documentation support and a wide cleanroom portfolio (match ISO class, packaging, and sterility needs).
- Kimtech nitrile cleanroom lines: Commonly evaluated for controlled-environment handling where published cleanliness context and packaging controls are required.
- Other cleanroom nitrile families in the TechNiGlove portfolio: Consider longer cuff options when sleeve coverage and reach are higher-risk factors.
12) Program fit (who standardizes this and why)
TN300W fits programs that want an ISO Class 5-positioned nitrile glove with published particles/ions/NVR/ESD attributes and cleanroom packaging, without moving into a fully sterile glove workflow.
Typical standardization drivers include: high-throughput bench work in controlled environments, ESD attraction risk control, and a desire for published cleanliness baselines to support investigations and operator training.
- Procurement: Case pack is 1,000 gloves (10 x 100). Availability on SOSCleanroom listing is stated as 7–10 business days (confirm at ordering for project schedules).
- Documentation: Certificate of Conformance available on request—use this as part of your receiving/qualification package when implementing change control.
- Training leverage: Published cleanliness/ESD metrics can be used in technician training to explain why glove choice and handling discipline directly affect yield and audit outcomes.
