Category B Biological Substances (UN3373)

Category B biological substances assigned to UN3373 must be transported in accordance with Packing Instruction 650 (P650).

At Versapak we manufacture and supply a range of specialist Diagnostic Specimen carriers which enables our customers to comply with these regulations. The insulated, protective carriers are user-friendly, cost-effective and have been tested to pass the 1.2m drop test as required by P650. The carrier can be secured using Versapak’s very own locking mechanism and patented T2 security seals.

Primary, Inner and Outer Packaging

A Versapak medical carrier forms the outer packaging of the UN3373 compliance.  A primary receptacle is required and usually dictated by the laboratory.  We supply Versapak Medical Carriers in small (6 litre), medium (18 litre) and large (35 litre) internal capacities to suit most laboratory and medical requirements. Anti-spillage liners make-up the inner packaging and are also supplied in small, medium and large sizes to suit carriers. Fastening clips are applied to the liners, preventing issues with samples leaking inside the outer packaging when used with our absorbent pads.
