ConductScience Nitrile Gloves, Large, Powder-Free, Black (Case of 10)
$75.00 per unit | 10 units per pack Bulk pricing: Case of 10 at $750.00 ($75.00 per unit)
ConductScience Nitrile Gloves provide essential hand protection for laboratory work requiring chemical resistance and tactile sensitivity. These powder-free gloves feature 5.0 mil thickness construction from synthetic nitrile rubber, offering barrier protection against a broad spectrum of chemicals while maintaining dexterity for precision tasks. The textured fingertips enhance grip control when handling glassware, instruments, and specimens.
Designed for single-use applications, these black gloves resist punctures and tears while providing excellent fit and comfort during extended wear. The powder-free formulation eliminates potential contamination from glove powder, making them suitable for sensitive analytical procedures and sterile environments. The black coloration helps conceal stains and provides professional appearance in laboratory settings.
How It Works
Nitrile gloves function as a chemical-resistant barrier through the molecular structure of synthetic nitrile rubber (acrylonitrile-butadiene copolymer). The cross-linked polymer chains create a flexible matrix that resists penetration by many organic solvents, oils, and aqueous solutions while maintaining elasticity and tactile sensitivity. The 5.0 mil thickness provides optimal balance between protection and dexterity.
The textured fingertip surface increases friction coefficient through microscopic surface irregularities, enhancing grip strength on smooth surfaces such as glassware and plastic labware. The powder-free manufacturing process uses chlorination or polymer coating to reduce surface tackiness, eliminating the need for dusting powders that could contaminate sensitive procedures. The black pigmentation is incorporated during polymerization to provide uniform coloration without affecting barrier properties.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Material Construction | Nitrile rubber (acrylonitrile-butadiene copolymer) | Latex or vinyl construction in basic examination gloves | Provides superior chemical resistance and eliminates latex allergy concerns for sensitive users. |
| Wall Thickness | 5.0 mil thickness | Standard examination gloves typically 3-4 mil | Enhanced durability and puncture resistance for demanding laboratory applications. |
| Surface Treatment | Textured fingertips with powder-free formulation | Smooth surface or powdered options | Improved grip control while eliminating contamination risks from glove powder. |
| Color Option | Black coloration | Typically blue or clear/translucent options | Conceals stains and provides professional appearance in research settings. |
These gloves combine nitrile chemical resistance with enhanced 5.0 mil thickness and textured fingertips for demanding laboratory applications. The powder-free, black design provides both performance and professional appearance for research environments.
Practical Tips
Change gloves between different chemicals or samples to prevent cross-contamination and ensure continued barrier protection.
Why: Chemical residues can compromise subsequent procedures and barrier integrity may be reduced after chemical exposure.
Inspect gloves before each use for pinholes, tears, or signs of chemical degradation such as swelling or discoloration.
Why: Compromised barrier integrity can lead to skin exposure and contamination of samples or procedures.
Remove gloves using proper technique by peeling from wrist to fingertips without touching outer surface.
Why: Prevents contamination of hands and work surfaces during glove removal.
Store unopened boxes in temperature-controlled environment below 80°F and away from ozone sources.
Why: High temperatures and ozone exposure accelerate nitrile degradation and reduce shelf life.
Test chemical compatibility with a small sample before extended exposure to new chemicals.
Why: Chemical permeation rates vary and some chemicals may cause rapid degradation not visible immediately.
Use powder-free gloves for sensitive analytical procedures involving trace metal analysis or particle counting.
Why: Glove powder can interfere with analytical measurements and contaminate sensitive samples.
If gloves feel sticky or difficult to don, check storage conditions and expiration date.
Why: Improper storage or aging can cause surface degradation affecting donning characteristics.

Compliance
What is the breakthrough time for common laboratory solvents?
Consult chemical compatibility charts for specific solvents. Nitrile generally provides good resistance to aliphatic hydrocarbons and moderate resistance to aromatic solvents, with breakthrough times varying by chemical concentration and contact duration.
Are these gloves suitable for cytotoxic drug handling?
These are examination-grade gloves, not chemotherapy-rated. For cytotoxic drugs, consult NIOSH criteria and use appropriate double-gloving protocols with chemotherapy-tested glove systems.
How does the 5.0 mil thickness compare to standard examination gloves?
This thickness provides enhanced durability compared to typical 3-4 mil examination gloves while maintaining adequate tactile sensitivity for most laboratory tasks.
Can these gloves be used in autoclave applications?
Not recommended. Nitrile degrades under autoclave conditions. Use heat-resistant materials for steam sterilization applications.
What is the shelf life and storage requirements?
Typically 3-5 years when stored in cool, dry conditions away from ozone and UV light. Avoid storage near electrical equipment that generates ozone.
Are these gloves latex-free?
Yes, nitrile gloves contain no natural rubber latex proteins, making them suitable for latex-sensitive individuals.
How do I verify proper fit for laboratory work?
Gloves should fit snugly without restricting circulation, with fingertips reaching glove tips and adequate wrist coverage. Test dexterity with typical laboratory tasks before extended use.
