Product Description
Volatile compounds escape quickly through a poor seal, and the wrong septum can react with aggressive samples. These caps use a bonded white PTFE liner to protect volatile and chemical samples, with the cap and liner pre-assembled to cut handling and contamination.
This listing is for Kimble catalog number N73805-24: Polypropylene Screw Thread Caps, 24-400, Case of 144. Caps are polypropylene with a bonded PTFE liner and are intended for single-use injection. They are autoclavable and offered in 8-425, 13-425 and 24-400 threads. The N73805-24 is a patented KIM-LOC design with 0.010 inch PTFE that eliminates leakage caused by cap cocking.
