Kimtech Polaris carries dual certification—EN 374 chemical protection and EN 455 medical examination compliance—in a single food-contact-approved nitrile glove built for scientific laboratories, cleanroom environments, and food production lines that need documented protection against chemicals and micro-organisms.
Why This Glove Stands Out
EN 374 dual-certification separates the Polaris from standard exam nitrile. EN 374 validates resistance to chemical permeation (Type A/B/C designation based on the breadth of chemicals tested), not just barrier protection from pathogens. A glove that passes both EN 374 and EN 455 is validated for both chemical exposure and medical examination use—a combination that eliminates the need for two separate glove SKUs in lab environments.
Performance and Fit
At approximately 6 mil, the Polaris is heavier than standard 3–4 mil exam gloves. This added gauge contributes to better puncture resistance in laboratory settings where glassware, sharp metal fittings, and chemical container edges create puncture hazards. Tactile sensitivity is reduced compared to thin exam gloves but remains appropriate for most lab procedures and food-line quality control inspections.
Food contact approval means the Polaris has been evaluated for migration of materials from the glove into food—a compliance standard separate from chemical resistance and medical exam ratings. This makes it a single glove choice for food production facilities with chemical handling requirements in the same workflow, where separate gloves for food contact and chemical handling would otherwise complicate inventory and protocol.
Durability and Chemical Protection
EN 374 Type A/B/C indicates the glove has been tested against multiple chemical challenge agents at defined permeation breakthrough times. The specific chemicals covered are documented in Kimtech's technical data sheet—consult it before using the Polaris against chemicals not in the tested set. The Polaris is appropriate for many organic solvents, acids, and bases in laboratory settings at the gauge and specification tested.
Pros and Cons
Pros
- EN 374 Type A/B/C chemical protection certification—not just standard exam barrier
- EN 455 medical examination compliance dual-rated with food contact approval
- Cleanroom compatible design suitable for controlled-environment lab work
- Kimberly-Clark manufacturing quality with tightly controlled AQL
Cons
- 50 per box at premium price—higher per-pair cost than standard 100-count exam gloves
- ~6 mil reduces tactile sensitivity versus 3–4 mil thin exam options
Who Should Buy This Glove
Order for scientific labs, quality control environments, cleanroom operations, and food production facilities that need a single glove meeting chemical protection, medical exam, and food contact standards simultaneously.
Who Should Skip It
Skip for budget-focused exam use—50 per box at Kimtech pricing is premium for basic clinical glove changes. For food service without chemical handling, a standard 100-count exam glove is more economical.
How It Compares
The Kimtech Sterling (gray, 200/box) is the high-count lab option without the EN 374 chemical rating. The Kimtech Purple (USP 800, 5.9 mil) addresses hazardous drug handling specifically. The Ansell TouchNTuff 93-800 (EN 374, extended cuff, 8.3 mil) handles heavier chemical tasks beyond the Polaris range.

Frequently Asked Questions
What does EN 374 Type A/B/C mean for the Polaris?
EN 374 Type A = tested against 6+ chemical challenge agents with breakthrough times exceeding 30 minutes; Type B = 3+ chemicals; Type C = 1+ chemicals. A/B/C on a single glove means it meets the highest chemical breadth tier across multiple chemical families.
What does EN 455 certification cover?
EN 455 covers medical gloves for single use—physical dimensions, freedom from holes, physical properties, and shelf life (EN 455-1 through EN 455-4). Together with EN 374, the Polaris is validated for both chemical and clinical use.
What does 'food contact approved' mean?
The glove material has been evaluated for migration of substances into food, meeting EU or equivalent food contact regulations. This allows direct contact with food products in production and processing environments.
Is the Kimtech Polaris a cleanroom glove?
The Polaris is cleanroom-compatible at standard cleanliness levels. For ISO 5 (Class 100) or higher cleanliness requirements, verify with Kimtech's technical team for your specific ISO class.
How does the Polaris compare to standard ASTM D6319 exam gloves?
ASTM D6319 validates physical barrier performance (AQL, tensile strength, elongation). EN 374 adds chemical permeation resistance testing. The Polaris meets both European (EN) and provides equivalent performance to ASTM-rated gloves, with the additional EN 374 chemical protection layer.
Are these latex-free?
Yes. 100% nitrile—no natural rubber latex.
What size range is available?
XS through XL. Confirm sizing with the Kimtech fit guide before bulk ordering.
How many pairs in a 50-count box?
25 pairs. Ambidextrous design.
Can I use these for hazardous drug handling under USP 800?
EN 374 chemical protection covers a broad range including many hazardous drugs. For formal USP 800 compliance in pharmacy compounding, the Kimtech Purple is specifically marketed with USP 800 rating—verify current regulatory requirements with your compliance team.
What is the shelf life?
Three to five years in cool, dry storage.
Are these gloves powder-free?
Yes. Powder-free—no talc contamination for food, lab, or clinical environments.
What is the color?
Blue—standard for clinical and lab identification.
How does the Polaris compare to the Kimtech Sterling?
The Sterling (gray, 200/box) is the high-count lab workhorse without EN 374 chemical certification. The Polaris costs more per pair but adds EN 374 chemical protection for environments with chemical handling requirements.
Is EN 374 the same as ASTM F739?
Different standards, similar purpose. ASTM F739 is the North American standard for chemical permeation testing; EN 374 is the European equivalent. Both measure breakthrough time—the Polaris is rated to EN 374.
Where can I find the chemical resistance data?
Kimtech publishes technical data sheets listing tested chemicals and breakthrough times for the Polaris—available through Kimberly-Clark's professional product documentation portal.
The Bottom Line
The Kimtech Polaris earns its premium positioning through genuine dual-certification—EN 374 chemical protection and EN 455 medical exam compliance with food contact approval in one glove. For lab and food production environments that would otherwise carry two or three separate glove SKUs, it is an operationally meaningful consolidation.
