Specialised Tamper Proof Tape ( 200 labels )
It is best practice to send your vials to the lab for analysis in a state that requires them to be tamper proof. The words tamper proof appear on each label. Once the vial has been sealed with the Tamper Proof Tape opening the vial it will cause the tape to break. The broken tape is an obvious and definitive sign that the seal has been tampered with.
