Caps, Screw Top, with Silicone Rubber / PTFE, low durometer Septa, bonded in "knurled", polypropylene, Red Caps. For use with 9-425mm thread, 12x32mm autosampler vials. MICROSOLV Brand. 1000/CS.
Additional Info:
Low durometer septa are formulated to reduce penetration force, helping improve injection consistency while minimizing stress on autosampler needles.
The 9502S‑10C‑R‑M screw caps feature bonded silicone/PTFE septa with a softer formulation to allow easier needle entry while maintaining reliable sealing performance. The bonded septa design helps prevent “septa plunge” and eliminates the risk of liners falling out or becoming dislodged during transport or use.
These caps provide a cost-effective alternative to higher-priced certified options while delivering dependable performance for routine HPLC and GC applications. The red polypropylene cap includes a knurled exterior for secure handling and consistent sealing on standard 9‑425, 12 × 32 mm autosampler vials.
