Where to Buy Specimen Bags in Canada: 95 kPa Sizes and Bulk Options
A specimen bag is chosen by the sample, not by the shelf: too small and the tube will not seal flat, too large and the sample slides in a bag meant for far more. This guide covers where Canadian clinics and labs buy 95 kPa specimen bags, how the sizes map to sample volumes, and what to confirm before ordering a case.
Where can a Canadian clinic or lab buy specimen bags?
Specimen bags reach Canadian clinics and labs through licensed medical device distributors, and the useful test is a supplier that ships the case within the country and stocks the sizes your send volume needs. The 8 by 10 inch 95 kPa specimen bags, 100-pack cover a mixed daily batch, and smaller or larger sizes are matched to the sample.
How do the 95 kPa sizes map to samples?
| Bag size | Typical contents |
|---|---|
| 6 by 9 inch | A single tube or a small swab sample |
| 7 by 11 inch | One or two containers |
| 8 by 10 inch | A mixed batch of tubes |
| 12 by 15 inch | Larger containers or a full set |
The rating is a pressure test: a 95 kPa bag is built to hold a 95 kPa pressure differential, which is what the secondary packaging for UN3373 Category B samples has to withstand. Size and rating work together, because a bag that is too small to seal flat cannot protect the sample inside it.
What should you confirm before ordering?
Four checks cover most of the risk. The pressure rating first, so the bag matches the Category B packaging requirement. The seal second, because a leakproof closure is what keeps the sample from escaping if the bag is dropped. The document pouch third, since the paperwork travels in a separate compartment from the sample. The case size fourth, so the box is used inside the shelf life the maker states. A draw station that sends single tubes on their own only needs the small size, while a batch send uses the larger bag, so the size mix follows the samples a clinic actually takes rather than a single order. Larger sends use the 12 by 15 inch specimen bags, and a single-tube clinic keeps the 6 by 9 inch specimen bags on the draw station.

Frequently Asked Questions
Where can a Canadian clinic buy 95 kPa specimen bags?
Specimen bags are supplied through licensed medical device distributors, and a Canadian supplier ships the case within the country. Order the size that matches the sample volume your clinic sends most often.
What does the 95 kPa rating mean?
A 95 kPa bag is tested to hold a 95 kPa pressure differential, which is the pressure requirement for the secondary packaging used to move UN3373 Category B samples.
Which bag size should a clinic stock?
Short 6 by 9 and 7 by 11 bags suit single tubes and small samples, 8 by 10 covers a mixed batch, and the 12 by 15 size takes larger containers. Most labs keep two sizes.
Do specimen bags need a document pouch?
A Category B secondary package holds the sample in a leakproof bag and the paperwork in a separate compartment, so the request form does not touch the sample if the bag is dropped.
