24-400 EPA Vials
&©|61623;EPA Test Methods 5030 and 5035 are focused on ***ermining the amount volatile organic compounds (VOCs) found in either a solid or aqueous sample.
&©|61623;Examples of these compounds include chlorinated solvents and fuel additives. With both methods, a sample is typically housed in a 40ml EPA VOA vial with an open top cap and septa. The septa used in these EPA vials are typically made of a silicone/PTFE construct, 0.125¡± thick.
&©|61623;The PTFE acts as the main barrier to minimize contamination during sample handling.
&©|61623;Because of the nature of the method and level of sophistication of equipment, EPA laboratories can measure VOCs to extremely low levels with some measuring &©|8249; 1 ppb. As a result, it is imperative that the EPA septa not contain any form of contamination.
&©|61623;Through special conditioning and use of cleaner materials, we have been able to consistently deliver clean EPA septa for use in EPA VOA vials. Each production run of EPA septa is tested to ensure compliance to EPA Method 5035 and the test report can be supplied upon request.
Product Feature:
"Ready to use combination seals; no time-consuming and ¡°tricky¡± assembly No contamination of the liner with sweat/fat that normally is caused by
.manual assembly .Available as closed top screw seals or with centre hole in white 24-400 caps .Broad variety of different septa materials for almost all applications Also UltraBond Seals ND24 are offered, i.e. that the cap and the
Silicone/PTFE liner of these seals form an inseparable unit avoiding the
problem of liners falling out of the cap. This 100% firm fit of the liner is
achieved by a patented process that requires no adhesives, but instead
.changes the molecular structure of both components to achieve the fixation Also pre-sealed vials are available!"
