Septa selection guide Overview Diferent septa material for LC and GC applications There are many diferent types of materials used to produce the septa found in LC and GC vial caps. This document will provide you with the technical guidance you need in order to make the right selection. Choosing the right septa
the solvent. PTFE/Silicone septa are ideal for use in most HPLC and GC applications where resealability and purity are critical. Pre-slit PTFE/silicone septa Pre-slit septa are offered in many of the same formulations as for non-slit PTFE/silicone septa and shares most of the physical and chemical characteristics. The septum is provided with a
When it’s time for sample injection, you can trust the PTFE/Silicone Septum from Aijiren Technology to help you perform that process successfully. Our septa are held to a high standard of cleanliness and dimensional tolerances, as we believe you should only receive the cleanest products from us right out of the box. Tell your lab manager that you need

This includes ensuring that the cap is free of any potential contaminants that may cause chromatographic ghost peaks. These caps come 100 to a pack with 12 x 32 mm measurements, and other related products are available when you shop for lab equipment with Aijiren Technology, such as the Amber Glass 12 x 32 mm Screw Neck Vial, 2 mL Volume, 100/pk.
Silicone rubber septa. High quality, silicone rubber laminated to PTFE. Use when excellent resealing qualities are a must. Septum resists coring and is recommended when multiple injections are required. Preferred septa for use in liquid chromatography applications.
Stoppers, also known as bungs, are used to give an airtight seal to laboratory flasks and test tubes by fitting tightly inside the neck of the container and preventing material from spilling. Stoppers can be made of glass, cork, rubber, or silicone. They are typically designed with a conical shape, but straight, flanged, and tapered options are
CS Septa. PTFE-coated silicone septa for low temperature applications. Good durability, good resealing. Excellent solvent resistance; good tear resistance. Maximum temperature: 200°C (392°F)
Translucent silicone rubber septa:. Contain no pigments, waxes, or molding agents. Good for high heat applications (200C continuous or 400C intermittent). Autoclavable for sterile applications. Excellent resistance to deterioration due to sunlight and ozone. Compare this item.
The Merlin MicroSeal injection port septa is the perfect substitute to use in split/split less injection and SPME. It has the capacity to hold more than 2000 syringes depending upon the type of the syringe. Instrument downtime for septa changes and port liner changes is greatly minimized. It offers.

It's vital to choose the right septa for your application. The wrong septa can compromise the accuracy of your results and reduce the lifespan of your supplies (increasing overall costs). The below chart shows some common septa materials along with their compatibilities, incompatibilities, and resealability.
Ensure optimal performance of your GC instrument with bleed and temperature optimized Aijiren Tech™ BTO and TR-Green Septa. Made of low-bleed silicone, these septa have excellent mechanical properties, are ideal for demanding GC-MS applications, and may be used reliably up to 400 °C.
Description. Aijiren Tech™ Septa for 8-425 Screw Thread Caps are constructed of PTFE, PTFE/rubber, or PTFE/silicone to suit a variety of HPLC, GC and IC applications. Choose from Aijiren Tech™, Aijiren Tech™ National™, and Aijiren Tech™ Chromacol™ brands. PTFE Disk septa are chemically inert.
Bottle Septa. Septa for bottles provide an airtight seal for bottles that prevents environmental contaminants but allows for the removal of the bottle’s contents by piercing with sharp needles. Septa bottle caps are generally available for open-top and screw caps and allow for aseptic syringe dispensing, as well as the addition of materials.
