Tamper-Proof Cap with Lip Seal and Capinsert, White Polyethylene, for 7 mL Tubes, 1000/pk

They are ideal for all applications requiring a tamper-evident seal in order to guarantee the utmost security and where sample integrity is of high importance.

Key Features

• Seal that needs to be broken in order to open it, which leaves an obvious visual indication that the vial has been opened.
• The ease of operation is due in part to the closure's unique frangible band design. This produces a combination tamper-evident and resistant closure system that provides benefits of safety and peace of mind.
• A perfect leakproof seal is obtained by the use of a specially designed flexible sealing lip inside the polyethylene closures. The cap also features a long skirt and a super-fast thread design allowing them to be removed or sealed with a single turn.
• Compatible with T552ATTP Tamper evident self-standing transport tubes - see chart below.
