You spoke, and we listened – and prototyped, tested, and finessed. The result is a versatile pipette tip rack with a hinged lid that rests open, detaches/reattaches, and snaps securely shut. In case of an accidental slip from the bench, the latch holds holds firm, protecting the BioClean UltraTM tips inside. And it's easy to open with one hand. For high-purity, zero-interference Rainin pipette tips, there's never been a more functional pipette tip rack.
