Product Description
Distinctive gold seals make it easy to spot a sample set on a crowded tray. This 20 mm gold seal pairs a thin-center PTFE/silicone septum with a crimp-on design for easy needle penetration and a secure closure. They are a practical way to color code sample batches.
This listing is for Wheaton catalog number W224323: Gold A/S Seal, Thin Center PTFE/Silicone Septum, 20 mm, Case of 100. The septum's PTFE face is chemically inert toward samples, and the silicone backing reseals after piercing. Crimp the seal onto a standard 20 mm vial finish using an appropriate crimper. Supplied 100 per case. The thin center lowers penetration force for the autosampler needle, helping to keep injections smooth and consistent across long sequences. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
