Ask three Canadian clinic managers how they choose nitrile exam gloves and you will usually get three different answers: the one they have always bought, the one the last representative left behind, and the one that happened to be on promotion. None of those answers is a specification. Meanwhile the listings themselves speak in two different measurement languages, and catalogue tables cheerfully print a glove standard next to a face mask standard, which makes a straightforward comparison harder than it needs to be.
This guide is built around one asset: a selection matrix that maps six everyday clinic scenarios to the specification each one actually needs, the standard that sits behind it, the construction details that should appear on the label, and the cost per glove you should expect to pay. Work down the matrix once with your own clinic in mind and you will have a purchasing position you can defend in a budget meeting.
Why a scenario-first matrix beats a thickness ranking
Most glove buying advice is arranged as a ladder: 3 mil for light work, 4 mil for general use, 6 mil for heavy duty. The ladder is not wrong, but it answers a question you have not asked yet. Thickness is a property of the glove; it is not a description of your clinic. Two clinics can run the same monthly volume and still need different gloves, because one spends its day on phlebotomy and the other spends it disinfecting bed rails.
A scenario-first matrix flips the order. You start with what the hands are doing, then read across to the specification that suits it. The reading order is deliberate: scenario, then specification, then standard, then construction, then cost. If you read cost first, you will buy the wrong glove for the task and pay for it twice — once at the till, and again in gloves that tear at the wrong moment.
Axis one: what “mil” actually measures
A mil is one thousandth of an inch. Glove listings give it as a single-wall measurement, which is the thickness of the material itself rather than the combined thickness of two facing sides. In metric terms the numbers our listings publish are 4 mil = 0.10 mm and 6 mil = 0.15 mm.
This axis is the one that predicts mechanical performance. A heavier wall resists punctures, tears and abrasion for longer. It does not make a glove more comfortable, and it does not automatically make it suitable for a given clinical task — dexterity falls as the wall grows, which is why a heavier glove is not the “upgrade” it is sometimes sold as.
Axis two: what “3.5 g” means on a case listing
The second language is mass per glove, printed as a plain weight: 3.5 g, 4.0 g, 5.0 g. This is how the large manufacturers describe their lines, and it is a material-weight figure, not a thickness. It tells you how much nitrile went into the glove, which is a useful proxy for how substantial it feels in the hand.
The trap is that the two axes are not interchangeable. A 3.5 g glove and a 4 mil glove are not describing the same property, so putting them side by side in a comparison table and picking the bigger number is meaningless. When you compare two suppliers, compare the same axis. If one quotes mil and the other quotes grams, ask the grams supplier for the wall thickness as well, or the mil supplier for the mass. Any serious distributor can supply both.
The matrix, row by row
Here is the same matrix in text form, so you can copy the specification lines into a tender document or a purchase requisition.
| Scenario | Specification to ask for | Standard & quality signal | Construction | Cost per glove (CAD) |
|---|---|---|---|---|
| Routine exams, vitals, triage — high volume | 4 mil (0.10 mm), exam grade | ASTM D6319; AQL ≤ 1.5 published on the listing | Fingertip textured, beaded cuff, powder-free, latex-free | $0.080 by the box of 100; $0.055 by the 1,000-glove case |
| Phlebotomy, injections, fine palpation — tactile precision | 4.0 mil, chemo-grade | ASTM D6319; AQL ≤ 1.5 | Textured fingertips, beaded cuff, powder-free, latex-free | $0.080 by the box of 100 |
| Higher-risk exams, extended wear — heavier wall | 5.0 mil, fully textured | ASTM D6319; AQL ≤ 1.5 | Fully textured on palm and fingers, beaded cuff | $0.110 by the box of 100 |
| Cleaning, disinfecting, soiled handling — roughest tasks | 6 mil (0.15 mm), heavy-duty | ASTM D6319; AQL ≤ 1.5 | Fully textured, extended beaded cuff, powder-free, latex-free | $0.200 by the box of 100; $0.160 by the 10-box case |
| Volume exam supply on a case budget | 3.5 g, exam grade | ASTM D6319 performance; ISO 13485 manufacturing | Exam grade, textured fingertips, sizes S–XL | $0.080 by the 1,000-glove case |
| Food handling and general tasks — non-medical | 3.5 g, non-exam | Sold as a non-medical glove, not an examination glove | Non-exam weight, textured, blue or black, sizes S–XL | $0.080 by the 1,000-glove case |
Routine exams, vitals and triage
This is the glove that leaves the box most often in a general practice, a walk-in clinic or a long-term care station: blood pressure, temperature, wound checks, quick assessments. The requirement is a dependable barrier with enough feel to work a cuff and a thermometer, at a cost per glove that survives a 3,000-glove month. A 4 mil standard exam glove sits in the right place on both counts, and buying it by the case rather than the box moves the per-glove cost from $0.080 to $0.055.
Phlebotomy, injections and fine palpation
Here the matrix trades thickness for touch. Venepuncture, injections and any procedure where you are locating a vessel or a structure by feel rewards a thinner wall, because the sense of touch attenuates quickly as material is added. A 4.0 mil glove with textured fingertips keeps the tactile feedback without giving up the barrier, and textured fingertips matter more than most buyers expect once the glove is wet.
Higher-risk exams and extended wear
When a procedure is messy, prolonged, or likely to involve sharp instruments, the balance shifts back towards the wall. A 5.0 mil fully textured glove is the middle position: noticeably more substantial than the standard exam glove, but still thin enough to work in for an extended examination. Fully textured means the palm is textured as well as the fingertips, which is the difference you notice when gripping an instrument rather than a limb.
Cleaning, disinfecting and soiled handling
Environmental cleaning is the task that destroys gloves. Disinfectants, repeated donning and doffing, bed rails, soiled linen and sharps bins all shorten the life of a thin glove, and a glove that fails mid-task is worse than no glove at all. A 6 mil heavy-duty glove with an extended beaded cuff covers the rough end of the clinic's day. It costs about two and a half times the standard exam glove per unit, which is why the matrix does not recommend it for exam work — the correct answer for a high-volume exam room is to buy the right glove for the exam, not the toughest glove in the catalogue.
Volume exam supply on a case budget
Some clinics standardise on one glove for everything and want the simplest possible purchasing line. That is a legitimate strategy if the glove is an exam-grade nitrile with a published standard, and the case format is what makes it work: a 1,000-glove case keeps a single specification in stock across ten dispenser boxes without a repricing conversation every month.
Food handling and general tasks
The last row is the one that gets clinics into trouble. Food handling, general cleaning and non-clinical tasks do not require an examination glove, and buying an exam-grade glove for them is paying for a standard you are not using. The reverse of that mistake is worse: a non-medical glove must not drift into clinical use. Our non-exam lines are listed and sold as non-medical gloves for exactly this reason, and the matrix keeps them in their own row so the two never get confused on a purchase order.
The second lever: thickness and case quantity
Cost per glove is driven by two independent decisions, and buyers often collapse them into one. The first is the grade: moving from a 4 mil exam glove to a 6 mil heavy-duty glove multiplies the unit cost. The second is the buying unit: moving from a box of 100 to a case of 1,000 reduces the unit cost of the same glove.
The chart above is drawn to scale from the box and case variants on our own listings, verified in September 2026. Read it top to bottom and the shape of the market is visible: the most economical position is not the thinnest glove — it is the same 4 mil glove bought by the case. The most expensive position is the heaviest glove bought by the box, which is precisely the combination a clinic lands on when it decides to standardise on “the strong ones” without changing its order quantity.
Two practical conclusions follow. First, choose the grade for the task, then choose the quantity for your volume — not the other way round. Second, before you accept a unit price, ask what quantity it assumes. A quote that looks competitive per glove can be a box-quantity price dressed up as a case price.
What to check before you order
Three checks catch most of the problems.
- The standard is on the label. ASTM D6319 is the specification that applies to nitrile examination gloves. A listing that does not state a standard is not necessarily a bad glove, but you cannot verify it, and a clinic buying at volume should not be in that position.
- AQL, when it is published, is the pinhole acceptance limit. A lower figure is a tighter limit on the pinholes permitted in a production lot. Our exam lines publish AQL ≤ 1.5, and a certificate of analysis is available on request if your procurement file needs one.
- Powder-free and latex-free are two separate claims. Most modern nitrile gloves are both, but they are separate statements and they are separately verified. If latex sensitivity is a factor in your clinic, check that the listing says latex-free rather than assuming it from the word nitrile.
Two smaller items are worth a glance as well: the cuff type, because a beaded cuff resists roll-down during extended wear and an extended cuff gives more forearm coverage for cleaning work; and the sizes stocked, because a glove that is a size too large loses dexterity and fits poorly at the fingertips.
Two standards that get mixed up
The first confusion is between D6319 and F2100. ASTM D6319 is the glove standard. ASTM F2100 is the performance standard for medical face masks, covering bacterial filtration efficiency, particle filtration efficiency, differential pressure and fluid resistance. Because clinics order gloves and masks from the same catalogue page, the two numbers appear in the same table often enough that buyers start treating them as one family. They are not. If a glove listing quotes F2100, that is a conversation worth having with the supplier.
The second confusion is chemotherapy handling. The relevant measurement is ASTM D6978, which covers permeation resistance to a defined list of cytotoxic drugs. “Chemo-grade” is a manufacturer's description; D6978 is the test that quantifies it. If cytotoxic drug handling is part of your protocol, ask for the D6978 data specifically, and check which drugs the glove was tested against. We reviewed this in detail in our case review of a British Columbia oncology clinic that standardised on D6978-tested gloves, and in our explanation of AQL and pinhole testing.
How this fits the rest of your consumable ordering
Gloves are the highest-frequency consumable in most clinics, which is why they are the right place to start building a specification-based purchasing habit. The same logic applies to the rest of the shelf. If you are still working through the powdered versus powder-free question, our comparison of powdered and powder-free gloves covers it; if you want a feel for whether your consumption is in the normal range, see what Canadian clinics consume per month.
Sterilization monitoring is the other consumable category where specifications do the work. The CliniEco Learning Hub collects the guides by category, and if you are setting up an account or moving to volume purchasing, the wholesale and business account page is the fastest route to a quote. If you would like to see how we document verification before you commit to a consumable line, the biological indicator five-pack trial is a free way to see the paperwork standard we work to, drawn from the same supply chain that stocks our gloves.

Frequently Asked Questions
What thickness of nitrile glove should a Canadian clinic buy?
Match the wall to the task rather than picking one thickness for the whole clinic. A 4 mil (0.10 mm) exam glove covers routine assessments and high-volume work, a 4.0 mil glove with textured fingertips suits phlebotomy and fine palpation, a 5.0 mil glove sits in the middle for higher-risk exams and extended wear, and a 6 mil (0.15 mm) glove is for cleaning, disinfecting and soiled handling. Buying one grade for everything usually means paying for thickness where you do not need it.
Is a 3.5 g glove the same as a 4 mil glove?
No. They describe different properties. Mil is a single-wall thickness measurement, and 4 mil equals 0.10 mm. The gram figure is the mass of the glove, so 3.5 g is a material-weight specification. They tend to move together, because a heavier wall generally needs more material, but they are not interchangeable and you should compare suppliers on the same axis.
What does ASTM D6319 cover?
ASTM D6319 is the specification for nitrile examination gloves. It is the glove equivalent of the standards that apply to other protective products, and it is the number to look for on a listing when you want to confirm that a glove is sold as an examination glove with a defined performance specification.
Is ASTM F2100 a glove standard?
No. ASTM F2100 applies to medical face masks and covers their filtration and fluid resistance performance. It is not a glove standard. The confusion is common because gloves and masks appear in the same catalogue tables, so a mask standard and a glove standard end up printed side by side.
What should I ask for if my clinic handles chemotherapy drugs?
Ask for ASTM D6978 permeation data for the specific gloves under consideration, and check which cytotoxic drugs were included in the testing. D6978 is the standard that measures permeation resistance to chemotherapy drugs. Terms such as chemo-grade are useful labels, but they are descriptive rather than measurable, so the test data is what supports a purchasing decision.
Does buying by the case reduce the cost per glove?
Yes. On our own listings the same 4 mil exam glove is $0.080 per glove by the box of 100 and $0.055 per glove by the 1,000-glove case, a reduction of roughly a third. The 6 mil heavy-duty glove moves from $0.200 by the box to $0.160 on the 10-box case. Case pricing applies to the quantities shown on each listing.
