Kimtech G3 White Nitrile Cleanroom Gloves (56881, Small) — ISO Class 3 Handling Discipline With Double-Bag Transfer Control
Representative product image (SKU 56881).
1) Practical solutions in a critical environment
In ISO Class 3 (and similarly managed ultra-clean areas), gloves are not just PPE — they are a primary contamination-control input and one of the most frequent points of contact with tools, fixtures, and product. What matters is the full system: clean manufacturing, controlled washing, packaging that supports clean transfer, and operator technique that preserves glove integrity after donning.
Kimtech G3 White Nitrile (56881) is positioned for ISO Class 3 or higher cleanroom use with double-bag packaging intended to support controlled introduction into critical areas.
2) What it's for
- ISO Class 3+ component handling and precision assembly
- Optics/inspection work where fingerprints, residues, and rework are costly
- Non-sterile pharma/life-science support operations (where your CCS permits non-sterile gloves)
- Lab operations needing latex-free, powder-free selection with clean transfer controls
3) Why should customers consider this glove
- ISO Class 3+ positioning: built for ultra-clean environments where glove quality and handling discipline materially affect yield.
- Transfer discipline support: double-bag packaging reduces boundary-related contamination risks during material introduction.
- Operator performance: 6.0 mil nitrile with textured fingertips balances protection and tactile control for delicate parts.
- Hazard-handling reference: ASTM D6978 testing is commonly used as a screening reference for chemo drug permeation (confirm against your hazards and site requirements).
- Program stability: SOSCleanroom focuses on best-in-class consumables because critical environments cannot be compromised.
4) Materials and construction
- Nitrile, 6.0 mil thickness (size Small / 56881)
- Textured fingertips; beaded cuff
- Latex-free and powder-free
- Multiple ultrapure DI-water wash cycles referenced in manufacturer literature
5) Specifications in context
| Specification | Published / listed value |
| Brand / family | Kimtech G3 |
| SOS SKU | 56881 (Size Small) |
| Cleanroom use positioning | ISO Class 3 or higher |
| Material / thickness | Nitrile, 6.0 mil |
| Surface / cuff | Textured fingertips; beaded cuff |
| Sterility | Non-sterile |
| Case pack | 1,000 gloves/case (100/bag; 10 bags/case) |
| Country of origin | Thailand |
| Chemo testing reference | ASTM D6978 (as listed) |
6) Cleanliness metrics
| Metric | Published context | Practical meaning |
| Particles > 0.5 μm / cm² | Typical 600; Maximum ≤ 950 | Supports ISO Class 3+ intent; maintain by strict bag-transfer and "touch rules." |
| AQL | AQL 1.5 | Starting point; define event-based glove change triggers. |
| Washing statement | Multiple ultrapure DI-water wash cycles | Helps reduce typical surface contaminants; contamination control is still won or lost at transfer, donning, and change control. |
7) Packaging, sterility, and traceability
- Configuration: 100 gloves per bag; 10 bags per case (1,000 gloves total).
- Transfer intent: double-bagged; remove outer bag at the correct boundary before presenting inner bag into the clean area.
- Traceability: maintain bag-to-line linkage so investigations and deviations can be closed faster.
- Sterility note: if sterile gloves are required by your CCS/SOP, select a glove explicitly specified as sterile.
8) Best-practice use
- Double-bag transfer: remove outer bag at designated boundary; present only the inner bag into the clean area.
- Donning technique: pull from the cuff, not the fingertips.
- "Touch rules": once donned, treat door hardware, carts, keyboards, and phones as glove-change events unless your SOP controls them.
- Change triggers: define time-based and event-based changes (snag/tear, contact with non-controlled surfaces, solvent contact, visible residue).
- ESD programs: do not rely on glove properties alone — grounding, garments, humidity, and work-surface strategy must remain in-spec.
Matching consumables (ISO alignment matters)
For over 35 years, SOS and Texwipe have been close partners, and SOSCleanroom is the authorized Master Distributor of ITW Texwipe for the United States market.
9) Common failure modes
- Clean glove becomes a dirty tool: touching carts, door handles, badges, or keyboards after donning without changing gloves.
- Micro-tears during donning: pulling from fingertips or snagging on jewelry/tape edges.
- Transfer breakdown: bringing the outer bag into the clean zone or setting the inner bag on uncontrolled surfaces.
- Chemical mismatch: using a thin-gauge glove for prolonged chemical contact where compatibility is not validated.
- Wrong sterility state: using non-sterile gloves in a procedure that requires sterile barrier control.
10) Closest competitors
11) Critical environment fit
U.S. standards first: glove selection is typically controlled through a CCS, ISO 14644 terminology, and risk-based SOPs aligned to applicable FDA expectations and ASTM/IEST practices.
EU GMP Annex 1 as a secondary benchmark: reinforces risk-based contamination control, disciplined gowning, material transfer controls, and investigation-ready documentation — not a U.S. legal requirement.
12) Customer SOP disclaimer
This Technical Vault entry is general cleanroom best-practice education and a starting template for evaluation. It is not a substitute for your validated procedures. Always follow your site's approved SOPs and quality requirements, and validate glove selection, transfer steps, donning/doffing method, glove-change frequency, and chemical compatibility against your materials, risks, and acceptance criteria.
