Septa for 24-414 Open Top Caps

Low-Bleed Silicone/PTFE Septa:
Specially designed and manufactured for high performance and low bleed, these septa are pigment-free and are comprised of top quality, virgin materials. PTFE film provides an excellent chemical barrier and the silicone has good resealability characteristics. Max temperature rating for this style is 200 C. Independent testing has shown a significant improvement in bleed compared to other standard septa in the market. 

PTFE/Chlorobutyl Septa:
Our Butyl septa are manufactured from a high quality, custom formulated compound and exhibit excellent low permeability characteristics, very good chemical resistance, and can withstand temperatures up to 100 C. Butyl septa work especially well when in contact with ketones and acids and have good resealability performance.
