A specially moulded seal with a PTFE insert. Sealing surface of Butyl and PTFE affects a more positive seal than non-PTFE-faced septa. Ideal choice for temperatures below 125°C. Good sealing characteristics, excellent resistance to most solvents with reduced coring and high puncture tolerance.
General description. Mini-UniPrep is a preassembled filtration device consisting of a 0.4 mL capacity chamber and a plunger. The plunger contains a filtration membrane at one end and a preattached cap/septum at the other. The plunger is pressed through the sample in the outer chamber and positive pressure forces the filtrate into the reservoir

Mar 17, 2009 · New PRE-CUT Septa for HPLC Applications. Mar 17 2009. In HPLC often slitted or cross-slitted Silicone/PTFE Septa are used, in order to offer a penetration aid for the fairly thick and dull needles used in the HPLC instruments. While the instrument needle requires the slitted septa, the user may run into the risk of concentration changes due to
Jun 13, 2022 · In the same way, some key features of pre-slit septa are that it can be Pre-slit I or +. It can be pre-slit PTFE or Silicone septa. Usually, its diameter measures 8mm to 22mm with a thickness of 1mm, 1.5mm, and 3mm. Most of which are made of either PTFE or silicone material. Again, pre-slit septa in vials aid in piercing easily.
Select Level 2 products for high-throughput applications, when robustness and reproducibility are key. Choose from polypropylene caps with all-purpose silicone/PTFE septa of various hardness values designed to reduce autosampler needle issues. Pre-slit and bonded septa options are available.
Used primarily for routine analysis in gas chromatography with FID, TCD and FPD detectors or HPLC with UV/Vis or RI detectors, PTFE/Synthetic Red Rubber septa offer good resealability and excellent chemical inertness before puncture. The low durometer of red rubber allows for easy needle penetration even with thin bore GC needles.
