Most facilities buy one exam glove for every job, and it is usually a 4 mil blue nitrile. That is a reasonable default. It is also why housekeeping wears a glove built for blood exposure, the lab wears a glove too thin for solvent work, and the whole building pays nitrile prices for tasks a vinyl glove covers. This exam glove material guide lays out the tradeoffs among nitrile, vinyl, and latex, explains when 3.5, 5, and 8 mil actually matter, and shows how to set a latex policy and buy by the case or pallet.
What an exam glove is, and is not
FDA regulates examination gloves, surgical gloves, and chemotherapy gloves as Class I reserved medical devices that require a 510(k) premarket notification. FDA reviews them for leak resistance, physical properties, and biocompatibility, and requires manufacturers to identify the glove material on the package label so a latex-sensitive user can choose an alternative.
Each material has its own ASTM specification: D6319 for nitrile, D5250 for poly(vinyl chloride), and D3578 for natural rubber latex. All three set requirements for tensile strength and elongation; D6319 adds freedom from holes and a residual powder limit, and D3578 adds protein content testing for latex. A general-purpose or food-service glove without a 510(k) is not an exam glove, whatever the box says. For clinical use, specify exam grade and ask for the 510(k) number on the quote.
The exam glove material guide: nitrile, vinyl, latex
The ratings below follow Intco Medical's published comparison guide.
| Nitrile | Vinyl (PVC) | Latex (natural rubber) | |
|---|---|---|---|
| Puncture resistance | Excellent | Low | Good |
| Chemical resistance | Excellent, often better than latex | Low, short contact only | Medium, degrades with some oils and solvents |
| Fit and tactile feel | Good, warms to the hand | Low, loose fit | Excellent, second-skin feel |
| Allergy risk | Low, latex-free | Low, latex-free | High, natural rubber proteins |
| Unit cost | Highest | Lowest | Middle |
| ASTM spec | D6319 | D5250 | D3578 |
| Best for | Clinical care, EMS, corrections, lab, janitorial with chemicals | Food handling, housekeeping, short low-risk tasks | High-dexterity procedures where the facility manages allergy risk |
Nitrile is the default for any task with blood, body fluid, sharps, or chemical exposure. Vinyl earns its place where the glove comes off every few minutes and nothing hazardous is on the other side of it. Latex survives in dental and surgical settings where feel matters and the facility screens for sensitivity, but it is the wrong default for a mixed building.
Mil thickness: when 3.5, 5, and 8 mil matter
A mil is one thousandth of an inch. Thickness is measured at the fingertip, the palm, and the cuff. The fingertip is usually the highest number and the palm is the one printed on the box. When you compare quotes, confirm both state the same zone.
- 3.5 to 4 mil. The standard clinical glove for routine exams, dental, lab pipetting, and medication administration. Best tactile feel, changed often. Maxter's USA-made 3.5 mil (M9399), Raxwell's 4 mil chemo-rated RX301, and Intco's Synguard 4 mil (NGPF700) all sit here.
- 5 to 6 mil. Phlebotomy, EMS, corrections, and janitorial work with harsher cleaning agents. Longer wear before failure and longer chemical breakthrough time. Raxwell's RX PRO black nitrile at 6.5 mil (RXE2023) is the corrections and EMS pick.
- 8 mil and up. Mechanical work, paint, agriculture, decontamination, and any task where the glove stays on for hours against oils or sharp edges. Extended-cuff styles such as Raxwell's 12 inch RX4000 at 8.5 mil add forearm coverage; note the 50 per box pack.
Thicker is not free. Fine-motor tasks get harder above 6 mil, hands fatigue sooner, and the box costs more. Buy the thinnest glove that survives the task, and stock a heavier glove only at the stations that need it.
Latex allergy policy and the powder-free standard
Two facts shape glove policy.
First, FDA banned powdered surgeon's gloves, powdered patient examination gloves, and absorbable glove powder effective January 18, 2017, citing airway inflammation, hypersensitivity reactions, and adhesion risk, and noting that powder on latex gloves can aerosolize latex allergens. Every exam glove you buy today should be powder-free, and the quote should say so.
Second, NIOSH's workplace latex alert reported that 8 to 12 percent of healthcare workers regularly exposed to latex are sensitized, against 1 to 6 percent of the general population. NIOSH recommends non-latex gloves for tasks not likely to involve infectious materials, such as food preparation, housekeeping, and maintenance, and reduced-protein, powder-free latex where latex is chosen.
The procurement answer:
- Make nitrile or vinyl the house standard and put latex on a restricted list that requires a department request.
- Require the material on every quote line. FDA already requires it on the package; make the supplier state it up front.
- Keep one latex-free alternate approved for every latex SKU still in use, so a reaction or an allocation does not restart sourcing.
Occupational health owns the clinical side of the policy. Purchasing enforces it through the item master.
Case and pallet pricing tiers, and Net 30
Exam gloves price in three tiers. Box pricing is for samples and one-off buys. Case pricing, typically 10 boxes of 100 (50 per box on heavy extended-cuff styles), is the working unit for clinics, school districts, and departments. Pallet pricing is the tier for hospitals, corrections systems, senior living groups, and industrial buyers who turn a pallet in a quarter or less; the per-glove price drops because freight and handling spread across the load. Basic Medical's 3.5 mil blue nitrile pallet program, stocked in Edina for next-day pickup, is built for that buyer.
Three habits get you the best tier without overbuying:
- Standardize to two or three glove SKUs per building so volume concentrates.
- State the size mix per case on the order. Small and medium run out first in clinical areas; large and extra large run out first in maintenance.
- Put the two highest-volume SKUs on a standing order with lot and expiration documented at delivery.
Keystone quotes case and pallet tiers on one sheet, with manufacturer, item number, mil thickness by zone, material, and expiration on every line, and offers Net 30 to approved accounts.
