Product Description
Replace septa on your own schedule and keep favorite 9 mm caps in service. Loose septa let labs match the seal to the solvent and injection count instead of buying a new cap and septum combination for every method change.
This listing is for MicroLiter catalog number 09-0030: µL 9mm Septa For 9mm Screw Thread Caps, PTFE / Silicone, Pack of 100. Two constructions are offered for 9 mm screw thread caps: PTFE/silicone, which pairs a chemically resistant PTFE face with a resealing silicone layer, and PTFE/silicone/PTFE, which adds a second PTFE face for extra protection. Septa are post-baked to remove additional siloxanes, and both are sold separately from caps. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
Key Features
- PTFE/silicone – Good resealing for multiple injections.
- PTFE/silicone/PTFE – Second PTFE layer adds chemical resistance on both faces.
- Post-baked – Treatment removes additional siloxanes to reduce background.
- Sold separately – Pair with open top 9 mm caps already in stock.
