BiTran Bags

The BiTran bag system is designed for transporting wet tissue from one place to another, and for the short to long-term storage of tissue. Choose from 6 sizes of bag, manufactured from a special barrier film with a unique double zip lock closure. The barrier film is impermeable to formalin vapour, preventing hazardous vapour polluting the laboratory once the bag is sealed. Air is expelled from the bag by squeezing prior to closure. The double zip lock seal provides a leak proof closure that can be easily opened and closed as many times as required allowing the specimen to be re-examined whenever necessary.

Bags containing specimens are more easily stored in an organised manner than conventional rigid glass or plastic containers and because of their flexibility less formalin is needed to totally immerse the specimen. Filled BiTran bags can be safely stored in boxes for long periods of time. The bag and specimen can be incinerated when no longer required, further reducing exposure to formalin vapour.

Empty bags are lightweight, occupy minimal space, and can be easily labelled before use. Laboratories using the BiTran system benefit from improved management and a reduction in the cost of wet tissue storage.
