These bubble wrap envelopes can hold from 1 to 8 transport tubes. The sample tubes are placed with a small absorbent strip into the mandatory transport tube, which is then packed into the envelope. This ensures that ADR package instruction 650 is complied with.

The shipping envelope has been tested and approved in accordance with the ADR rules for UN 3373 – package instruction 650.

The envelopes can also be delivered with your desired recipient address and “Postage payed by recipient”. They can be spruced up a bit with a color indication of your choice – plus of course the mandatory texts according to the ADR rules.
