Agilent Screw Cap with PTFE Septa 2 Packs with 100 Caps Each - Total of 200 Caps
The Agilent 5183-2076 screw cap is a specialized closure designed for use with 12 mm, 2 ml screw top vials. The cap itself is made of polypropylene and is colored blue, which can aid in quick identification.
A key feature of this cap is the pre-slit septa, which is a combination of PTFE (Teflon) and silicone. The silicone provides a secure, leak-proof seal, while the PTFE layer, being chemically inert, protects the sample from interacting with the silicone or the cap material. The pre-slit design allows for a needle to easily pierce the septa for sample injection or aspiration, and then self-seals after the needle is withdrawn, which minimizes the risk of contamination and evaporation.
This cap is a vital component for analytical laboratories, ensuring sample integrity and reliable performance in chromatography applications.
