Standard flat disc PTFE/silicone septa for use with EP Scientific EPA Vials. Fits the standard 24-414 open top cap. Certifications: Processed to meet EPA Performance Based Specifications for Volatile Organic Analysis. Ordering information: Other sizes are available.
Septa are selected based on the chemical properties of the sample and the temperature to which the vial will be subjected during the analysis. PTFE/Silicone is for use with most organic solvents. PTFE/Silicone is not for use with chlorosilanes. It has good resealability and can withstand a temperature of 250°C.
Narrow-mouth septa bottles are available in clear or amber Type III glass equipped with a 0.045 in. thick blue PTFE/silicone septa in an open-top 24-414 polypropylene cap. . The I-CHEM molded-in septa retainer ring holds the septa securely in place without bonding to the cap, so septa can be remove
A specially moulded seal with a PTFE insert. Sealing surface of Butyl and PTFE affects a more positive seal than non-PTFE-faced septa. Ideal choice for temperatures below 125°C. Good sealing characteristics, excellent resistance to most solvents with reduced coring and high puncture tolerance.
