In gas chromatography,septum bleed is often attributed to the inlet septum,but the vial cap septum can also be a source. Fortunately,it’s easy to determine which septum is causing the problem and by identifying it so you can avoid the time and trouble of unnecessary inlet maintenance. Read on to learn how to identify vial cap septum bleed and also how to choose a GC septum that will
SSP''s lab products are used in chromatography research and the pharmaceutical and life sciences industry. Standard septa products are divided into five egoriesautosampler,GC septa,bonded caps,magnetic caps,EPA/VOA,and 96 well sealing mats. SSP can also create custom PTFE/silicone septa
General Purpose Gray Inlet Septa. CrossLab Gray General Purpose Inlet Septa featuesGC septa manufacturer CrossLab general purpose septa are made from an enhanced injection-molded silicone rubber and are good for routine use. The septa material,gray in color,is specified to withstand over 200 automatic injections at an injection port temperature of 350 °C.
DescriptionMade of low-bleed silicone,these septa have excellent mechanical properties and are ideal for demanding GC-MS appliions. ,555-8177EA,555-8184EA,555-8180EA,555-8182EA Product(s) marked with this syol are discontinued-sold till end of stock.
GC septa manufacturer now treats inlet septa to eliminate sticking in the GC inlet. With premium non-stick septa,you''ll never have to scrape bits of septum out of your inlet
The Inlet septa is an essential part of the sample introduction into a GC system. The purpose of the septa is to create a barrier which is penetrated readily from the nozzle needle and is maintained while the internal pressure is held up without contaminating the analysis. Septa
The other septa sizes of 9.5,12.7,& 17 mm diameter provide outstanding longevity at inlet temperatures up to 400 oc. Injection life of 400+ injections can be achieved with proper care & use of dual gauge needle GC autosampler syringes.

SSP''s lab products are used in chromatography research and the pharmaceutical and life sciences industry. Standard septa products are divided into five egoriesautosampler,GC septa,bonded caps,magnetic caps,EPA/VOA,and 96 well sealing mats. SSP can also create custom PTFE/silicone septa for your specific appliion.
A GC septum is loed at the top of the injection port and serves two functions1) providing a leak-free seal to maintain carrier gas pressure inside the system,and 2) handling repeated puncturing by a syringe needle for sample introduction purposes without severe coring or leaking. We offer a variety of septa to serve many functions.
This cap allows direct injection of a liquid by means of a syringe through a center hole on the cap and a rubber septum with PTFE lining. For use with 20 mL glass (part nuer 6000128) or
PTFE/High Performance Rubber is a highly pure synthetic red rubber septum that provides a reduced background level for specific GC appliions,employing sensitive detectors such as ECD or NPD. PTFE/Silicone Septa (T/S) has high-quality,low background/blank value,100% synthetic pure silicone septa.
SSP makes autosampler septa,GC septa,bonded caps,magnetic caps,EPA/VOA septa,cap mats,and re-sealable septa. Our silicone septa are platinum-alyzed for ultra-low bleed and we use only the highest-quality PTFE liners.

Ptfe/silicone rubber septa septum Pre-asseled caps and septa reduce the chance of contamination of the septa during sample preparation. 2) For our old customer,we will send free sample ,even though new designs sample,when have stocks.
A syringe needle pierces the rubber septum for the purpose of injection and,on withdrawal,the elasticity of the septum ensures that the hole reseals. Rubber septa are most commonly used to seal medicinal vials containing either a liquid or freeze-dried solid (which is
Usable to 400 °C inlet temperature.* New plasma coating eliminates sticking in the injection port. Precision molding ensures consistent,accurate fit. Septa have a CenterGuide design to minimize coring. (Not available on 9.5 mm,10 mm,and GC septum for sale Plug.) 5 mm and 11 mm septa are partially predrilled. Preconditioned and ready to use.
Ideal for use in most HPLC appliions and GC appliions where resealability and purity are critical. NoteBefore puncturing,septa have chemical compatibility of PTFE; after puncturing,septa may have chemical compatibility of Silicone. PTFE/Silicone/PTFE . Temperature range
Overtightening a septum nut will invariably reduce septum lifetime by increasing coring and splitting problems. Septum Bleed. All GC septa contain various amounts of volatile materials (e.g.,silicone oils,phthalates) that can be released when the septum is heated to analysis temperatures.
