Short answer: A 95 kPa specimen bag is the secondary layer of the UN3373 Category B packaging that carries diagnostic specimens. Canadian clinics and labs order them by the case, in sizes from 6 by 9 inches for a single container up to 12 by 15 inches when paperwork travels with the sample. The pressure rating is a transport requirement, not a marketing claim, so the bag should state 95 kPa on the packaging.
CliniEco supplies 
6 by 9 inch 95 kPa specimen transport bags in packs of 100, sized for a single collection container plus the requisition. The pouch has a separate document pocket so the requisition does not sit against the specimen, which is the detail that decides whether a bag passes an audit.
Where can a Nova Scotia clinic buy 95 kPa specimen bags by the case?
Order on four specifications: the pressure rating printed on the bag, the bag dimensions, whether there is a separate document pouch, and the pack or case count. A bag sold as a specimen bag without a printed 95 kPa rating is a general-purpose bag, and using it for Category B transport puts the shipment outside the rules.
Which bag size fits which specimen?
| Bag size | Typical contents | Packs per case | Where it is used |
|---|---|---|---|
| 6 x 9 in | One 50 to 120 mL container plus requisition | 100 | Physician office, dental, collection site |
| 7 x 11 in | Two small containers or one tall tube | 100 | Clinic lab, pharmacy compounding |
| 8 x 10 in | Two to three containers, paperwork | 100 | Community lab, LTC home |
| 12 x 15 in | Multi-site batch, larger containers | 100 | Courier consolidation, hospital send-out |
What does UN3373 packaging actually require?
Category B biological substances travel in triple packaging: a leak-proof primary receptacle, enough absorbent to take the entire contents if the primary fails, a leak-proof secondary packaging that holds 95 kPa, and a rigid outer packaging with the UN3373 mark and the responsible person’s details. The specimen bag is that secondary layer. Transport Canada and IATA set the packing instruction, and the shipper, not the courier, owns compliance with it.
How do clinics keep a specimen bag order from running out?
Count one bag per specimen plus a small allowance for re-draws, then set a par level of two weeks of use with a reorder point at one week. A site sending 40 specimens a day goes through about 900 bags a month, so a 100-pack is a busy week, not a quarter. Ordering in cases of 100 keeps the freight per bag low without turning the supply room into a warehouse.

Frequently Asked Questions
What does 95 kPa mean on a specimen bag?
It is the pressure differential the packaging must survive without leaking, which is the requirement for UN3373 Category B biological substances in transport.
Which bag size do most Nova Scotia clinics order?
The 6 by 9 inch bag covers most single-specimen sends; 8 by 10 and 12 by 15 inch bags are used when documentation or multiple containers travel together.
Can a specimen bag be reused?
No. Specimen transport bags are single use, and a bag that has carried a specimen is disposed of as biomedical waste.
