CT International NCP Series Nitrile Cleanroom Gloves — Class 100 / ISO 5, Non-Sterile, 12" Cuff, Anti-Static, Double-Bagged, Textured Palm (10 Bags x 100 / 1000 Case)

Cleanroom Gloves Nitrile ISO 5 / Class 100 12" (305 mm) Length Double-Bagged Anti-Static Textured Palm No Latex Proteins (Published)

Overview

CT International’s NCP Series is a Class 100 / ISO 5 compatible nitrile cleanroom glove built for controlled environments where the operator interface must stay disciplined: glove contact happens, so your glove spec must be consistent, clean-processed, and easy to standardize. A 12" beaded cuff helps maintain sleeve overlap, while the textured palm supports confident handling of tools, components, and materials without over-gripping.

SOSCleanroom curates glove programs for critical manufacturing and labs. If your workflow is electronics-focused, the published anti-static design also supports ESD-aware operations when paired with the correct grounding program and floor/footwear strategy.

Why this glove matters in ISO 5 / Class 100 operations

Controls the biggest contamination variable: Hands touch everything. A cleanroom-compatible glove reduces the risk of particles and residues transferring to product-contact surfaces.
Cleaner staging at the point of use: Double-bagging supports controlled transfer and helps keep gloves protected until they are introduced into the work area.
Better gown/glove interface control: 12" length and a tapered, beaded cuff support overlap and reduce wrist exposure during repeated motions.
Process-safe handling: Textured palm improves grip for critical handling, reducing drops, rework, and unnecessary contact events.
ESD-aware support (when electronics are involved): Anti-static gloves help reduce charge accumulation as one element of a broader ESD control program.

Typical cleanroom tasks supported

ISO 5 / Class 100 assembly and inspection work where low contamination transfer matters
Semiconductor, optics, and electronics manufacturing steps where ESD-awareness and cleanliness must co-exist
Pharmaceutical and life science controlled-environment tasks where gloves are part of the contamination control strategy
General controlled environment handling of tools, fixtures, and materials
Controlled transfers and staging (enabled by double-bagging)

Note: NCP is a non-sterile cleanroom glove. For aseptic processing steps requiring sterile presentation, select a validated sterile glove per your SOP/CCS. Always verify chemical compatibility and PPE selection using your hazard assessment and applicable SDS information.

Packaging and handling (clean transfer)

Published as double-bagged for controlled handling. Case unit is 10 bags x 100 gloves. Maintain bag integrity until introduction into the controlled area to reduce incidental contamination.

For best results, stage gloves in the correct gowning zone and open bags using your facility’s “clean to cleaner” transfer technique.

EU GMP Annex 1 alignment notes (practical)

Annex 1 programs treat gloves as part of the facility’s Contamination Control Strategy (CCS). Selection is only one control—performance depends on how gloves are donned, disinfected (if applicable), changed, and documented.

Donning discipline: avoid touching the exterior surface; confirm full sleeve overlap and stable cuff positioning.
Change triggers: define tear/snag, surface contact events, task changes, and time-based replacement rules.
Disinfection workflow: if your CCS requires glove disinfection, use validated agents/contact times compatible with nitrile; avoid over-wetting that can drive liquids under cuffs.
Traceability: control substitutions under change management and keep lot/expiry records per SOP.

Storage and lifecycle control

Store in a cool, dry location in original packaging; protect open boxes/bags from direct light exposure.
Use FIFO and ensure the correct size is available to prevent “over-stretch” tearing or poor tactile control.
Inspect before use and replace immediately if compromised (tear, pinhole, tackiness, or visible contamination).

Glove Education ISO 5 / Class 100 Nitrile Non-Sterile (Controlled Environment) ESD-Aware Notes Donning & Change Control

Cleanroom Gloves 101: How CT International NCP Supports ISO 5 / Class 100 Workflows (and Why Donning Discipline Matters More Than Most People Think)

In controlled environments, gloves are not just PPE—they are a contamination control tool. The glove you choose, how you bring it into the room, and how you wear it determines whether your hands become a controlled interface or the highest-risk contamination source on the floor.

1) What “ISO 5 / Class 100” means at the glove interface

ISO 14644-1 classifies cleanrooms by airborne particle concentration. But the real-world problem is contact transfer: even when air is controlled, particles and residues can still reach product surfaces by touch. Gloves help create a controlled boundary between the operator and the process.

Operator touch is unavoidable in many build, inspection, and handling steps.
Clean-processed gloves reduce uncertainty compared to general-purpose gloves that may shed or carry residues.
Consistency is a control: standardizing on one glove spec reduces variation shift-to-shift and site-to-site.

2) Why NCP is engineered for controlled environments

NCP is published as a Class 100 / ISO 5 compatible nitrile glove with anti-static attributes, a textured palm for critical handling, and double-bagged packaging to support controlled transfer and staging. Its 12" length and beaded cuff help maintain sleeve overlap and reduce wrist exposure.

Key build features	12" length; tapered, beaded cuff; palm textured; anti-static; double-bagged (published)
Mechanical targets	5.0 mil (+/-1); tensile 2072 psi / 14 MPa; elongation 500% (published)
Cleanroom test context	Particle/extractable testing per IES-RP-CC-005.2; sampling per MIL-STD-105E (published)

3) Donning (the part audits and yields often depend on)

Operator quick-start: If you only remember one rule, remember this: never touch the outside of the glove with bare skin.

Perform hand hygiene per SOP and allow hands to dry fully (wet hands increase tearing and reduce control).
Open the outer bag in the gowning zone; present the inner bag forward without contacting non-controlled surfaces.
Don the first glove by touching only the glove interior and cuff edge; avoid snapping the glove (snaps generate particles).
Don the second glove and then confirm sleeve overlap. The cuff should sit flat; rolling cuffs are a contamination and breach risk.
Once gloved, treat your hands as “clean tools”: keep them in controlled zones and minimize contact with garments and non-process surfaces.

Change control: define glove change triggers (tear, snag, touching a non-controlled surface, leaving the work zone, task transition, and time-based change). Many facilities also use double-gloving so the outer glove can be changed without breaking gowning discipline.

4) ESD in cleanrooms: why anti-static gloves are not optional in electronics workflows

In electronics manufacturing, contamination control and ESD control must work together. A glove can be clean but still allow charge accumulation if the overall ESD system is incomplete. ANSI/ESD S20.20 (and the technically equivalent IEC 61340-5-1) frames ESD protection as a program: personnel grounding, flooring/footwear, workstation grounding, and verification/testing—not a single product.

Anti-static gloves help reduce charge build-up during handling (one element of the program).
Grounding verification matters: wrist straps/heel grounders should be tested routinely to prevent “false security.”
Cleanroom reality: ESD programs must be compatible with gowning and particle discipline, so components are protected on both fronts.

5) Completing the control set (recommended add-ons)

Gloves work best when the surrounding workflow is controlled. These complementary items help reduce “recontamination loops” in ISO environments.

Texwipe cleanroom wipers: for bench, tool, and staging surface wipe-downs prior to handling (reduce contact transfer events).
Texwipe cleanroom swabs: for tight areas, fixtures, and small contact points where wipers cannot reach.
ESD verification tools: testers/monitors for wrist straps and grounding points to confirm the program is actually working.
