Kimtech Sterling delivers the highest box count in the Kimtech nitrile line—200 gloves per box in a distinctive gray colorway—built for high-volume laboratory and industrial environments where Kimberly-Clark quality is the standard and per-glove cost efficiency matters.
Why This Glove Stands Out
200 gloves per box is the defining operational feature. For labs running multiple researchers through daily glove changes, a 200-count box cuts restocking frequency in half versus standard 100-count alternatives. The gray color is unique in the nitrile glove market—cleanroom-adjacent labs and industrial quality control operations use gray for task-specific identification without the contamination-signaling connotation of blue or the industrial heavy-duty connotation of black.
Performance and Fit
Gray nitrile at approximately 6 mil provides a durable lab glove that handles standard chemical reagents, lab instruments, and cleanroom adjacent tasks. Kimberly-Clark's manufacturing quality at this specification means low AQL defect rates and consistent thickness—both critical for researchers who rely on glove integrity for contamination control across extended experimental sessions.
The 200-count box format works economically for high-volume facilities but creates a storage consideration: at roughly twice the volume of a 100-count box, the Sterling requires storage planning in tightly organized lab supply rooms. Many facilities manage this by ordering at the case level and maintaining rolling inventory. The per-glove cost advantage across a 200-count box is meaningful at Kimtech pricing.
Durability and Chemical Protection
Sterling occupies the standard exam-grade position in the Kimtech line—ASTM D6319 and EN 455 certified for physical barrier performance and medical exam use, but without the EN 374 chemical certification of the Polaris or the USP 800 chemo rating of the Purple. For labs handling standard reagents, solvents within the nitrile compatibility range, and biological samples, Sterling is the correctly-specified workhorse.
Pros and Cons
Pros
- 200 per box cuts restocking frequency and per-glove cost versus standard 100-count Kimtech options
- Gray color provides unique visual differentiation for task-specific glove protocols
- Kimberly-Clark manufacturing quality delivers consistent gauge and low AQL defect rates
- Suitable for both ASTM D6319 exam use and standard lab applications
Cons
- No EN 374 chemical protection certification—use Polaris for chemical-resistant lab environments
- 200-count box requires storage planning for tight lab supply rooms
Who Should Buy This Glove
Order for university research labs, industrial QC departments, and high-volume clinical facilities where Kimberly-Clark quality is the standard and 200-per-box count reduces reorder frequency and per-glove cost.
Who Should Skip It
Skip for environments requiring EN 374 chemical protection (use Polaris) or USP 800 chemo compliance (use Purple). Skip for small-scale or low-volume use where a 200-count box creates waste risk from shelf life.
How It Compares
The Kimtech Polaris (50/box) adds EN 374 chemical protection at higher per-glove cost. The Kimtech Vista (200/box, AQL 1.0) is the same high-count format with tighter defect control at premium price. The Kimtech Purple (50/box) covers the chemo-rated niche. For non-Kimtech 200-count alternatives, the Medline Restore 250-count offers the highest box count.

Frequently Asked Questions
How many pairs are in a 200-count Kimtech Sterling box?
100 pairs. The 200-count box contains 200 individual ambidextrous gloves—100 pairs.
Why gray nitrile instead of blue?
Gray offers task-specific color coding without the standard connotations of blue (food/exam) or black (automotive/industrial). In Kimtech's line, gray signals the lab-grade Sterling product family and differentiates it from the blue Vista and purple chemo gloves.
Is the Kimtech Sterling rated for chemical protection?
ASTM D6319 and EN 455 cover physical barrier performance and exam-grade AQL. For chemical permeation resistance (EN 374), use the Kimtech Polaris instead.
What is ASTM D6319?
The standard for nitrile examination gloves for medical application—covering minimum thickness, acceptable quality level (AQL) for defects, and physical performance under use conditions.
Can I use Kimtech Sterling in a cleanroom?
The Sterling is cleanroom-compatible for standard cleanliness levels. For ISO 5 (Class 100) or tighter requirements, verify with Kimtech's technical specifications for your ISO class.
Are these latex-free?
Yes. 100% nitrile—no natural rubber latex.
How do these compare to Medline Restore 250-count?
Medline Restore offers 250 per box with a colloidal oatmeal inner coating for sensitive skin in off-white color. Kimtech Sterling is 200 per box in gray, Kimberly-Clark manufacturing quality, without the oatmeal coating. For skin comfort priority, Medline Restore wins; for Kimtech brand consistency and gray color coding, Sterling is the choice.
What sizes are available?
XS through XL. Confirm sizing before bulk ordering.
Are these powder-free?
Yes. No talc contamination.
What is the shelf life?
Three to five years in cool, dry storage.
How does the ~6 mil thickness affect dexterity?
6 mil provides good durability for lab use with moderate dexterity. For tasks requiring the highest tactile sensitivity, a 3–4 mil exam glove is preferable; for most lab sample handling and instrument use, 6 mil is appropriate.
Can the Sterling be used for food service?
Yes—nitrile, powder-free, latex-free. Gray is atypical in food service color coding; verify with your local food service authority.
How does Kimtech Sterling compare to Kimtech Vista?
The Vista (also 200/box) is produced to AQL 1.0—a tighter defect control standard than standard AQL. Sterling provides standard lab-grade quality at lower per-glove cost; Vista is the premium choice for environments requiring the tightest defect control.
What is the beaded cuff?
A small roll at the cuff opening that aids donning, prevents rolling during use, and helps seat the glove securely at the wrist.
Is Kimtech Sterling appropriate for chemical handling?
For standard lab reagents within nitrile's compatibility range—yes. For organic solvents at prolonged exposure or aggressive acids—consult the chemical resistance chart and consider the Polaris (EN 374 certified) instead.
The Bottom Line
Kimtech Sterling is the right choice for high-volume lab and industrial facilities that want Kimberly-Clark quality, distinctive gray color-coding, and the per-glove cost efficiency of a 200-count box without the premium for EN 374 or USP 800 specialty certification.
