13mm threaded cap and septum: black PP sealing cap with PTFE/silicone septum

Type: One-piece snap-on seal cap
Opening: 6mm center hole
Key models:

SC10202: Red PTFE/white silicone + blue cap

SC10301: Three-layer septum + natural color cap

SC10101: Pre-opened white PTFE/red silicone

Pre-slit PTFE/Silicone Septa is designed for applications where larger sample volumes need to be injected from a vial to avoid aspiration. This septa allows ambient gas to balance the gas in the vial, reducing the vacuum created by a tight seal around the needle. The pre-slit design makes the septa easier to penetrate with a needle and releases the vacuum created when removing large samples from the vial, while maintaining chromatographic properties similar to un-slit septa.

Thread: 9mm short thread
Type: Closed top or 6mm center hole
