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
Jul 11, 2023 · The slit in Pre-slit PTFE/Silicone Septa allows for easy needle penetration and self-sealing, maintaining sample integrity by minimizing the chance of contamination or evaporation.
resealable materials . PTFE/Silicone septa are formulated for different hardness (durometer) meeting requirements of various needle types . Formulations offering highly consistent performance, lowest background/blank value, and good chemical compatibility, effective sealing/resealing and low penetration force make PTFE/silicone septa suitable
Generally, silicone septa are more easily pierced than red rubber or butyl septa. For thicker, hard-to-pierce septa, a small gauge (23 gauge) needle may be required, or a stronger S-needle can be used. Preslit septa are the best option for easy penetration, reducing the likelihood of coring.

The Aijiren Technologies inlet septa is made from strong silicone material and works well even at 35 degree C temperatures. This septa is compatible to use with , , 4890, , , GC columns. Application: For , , 4890, , , GCs This product is only available to. Compare this item.
Works well for applications where ease of needle penetration is important. A PTFE/Silicone with slitted septum allows for easier needle penetration as well as to release the vacuum that forms when a large volume of sample is withdrawn from a vial. This septum provides
employing a large diameter, blunt tip needle. PTFE Septa A solid disk of 0.010” thick PTFE offers superior chemical inertness against the most aggressive solvents. The thin membrane allows for easy penetration by most needles. PTFE septa are not resealable. They should be used with relatively short cycle times or single injection methods.
PerkinElmer. Thermogreen ® Injector Septa, extremely low bleed over a wide range of inlet temperatures -100 to 350 °C. Easier needle penetration and high puncture tolerance make this septum ideal for autosamplers. This septum is already conditioned and ready to use. Compare this item.
The low durometer of red rubber allows for easy needle penetration even with thin bore GC needles. PTFE/Red rubber septa are not recommended for multiple injections with long run times or retention of samples for further analysis after initial puncture. PTFE/silicone septa: (T/S) PTFE/Silicone is the most versatile septum material offered in
Mar 31, 2022 · PTFE disk septa. A solid disk 0.010″ thick, our PTFE stands better than the most aggressive solvents. At least when it comes to chemical inertness. Most standard gauge metal HPLC needles can penetrate the thin membrane. Do not use PTFE septa with the following because you can’t release PTFE septa: 1. volatile solvents, 2. fast cycle periods,
Blue aluminum, clear PTFE/red rubber septa 100/pk Green aluminum, clear PTFE/red rubber septa 100/pk 5181-1216 Red aluminum, clear PTFE/red rubber septa 100/pk 5181-1217 Silver aluminum, PTFE/silicone/PTFE septa 100/pk Silver aluminum, PTFE/silicone septa 100/pk Silver aluminum, PTFE/butyl rubber septa 500/pk 5061-3370

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.
The low durometer of red rubber allows for easy needle penetration even with thin bore GC needles. PTFE/Red rubber septa are not recommended for multiple injections with long run times or retention of samples for further analysis after initial puncture. PTFE/silicone septa: (T/S) PTFE/Silicone is the most versatile septum material offered in
