Thin Septa Vials. I-Chem. Clear borosilicate glass with 0.060 in. Thin Septa 40 mL clear septa vials feature a thin (0.060”) PTFE/silicone septa. The septum is easy to puncture with syringe needles and is ultrasonically bonded to the 24-414 polypropylene closure. No adhesive is used.
Prevent septa push through and over- and under-tightening. With Advanced Vial Closure System (AVCS) technology built into 9mm Autosampler Vial Screw Caps and Septa you will get an optimal, consistent seal every time. With just one turn, they offer easy-on, easy-off convenience, and are a cost effective alternative to caps with bonded septa.
PTFE-faced, silicone septa fits microscale threaded standard taper joints and 5/5 threaded caps. PTFE face offers chemical resistance while the silicone base resists syringe coring. Dimensions: 3mm x

Bottle Septa. Septa for bottles provide an airtight seal for bottles that prevents environmental contaminants but allows for the removal of the bottle’s contents by piercing with sharp needles. Septa bottle caps are generally available for open-top and screw caps and allow for aseptic syringe dispensing, as well as the addition of materials.
