How to store silicone septa

Septa. A wide range of serrated and non-serrated septa, and sleeve stoppers are available for use as temporary closures for glassware joints, tubes, bottles, NMR tubes, ampules, and cannulation techniques in air-sensitive chemistry. To protect your valuable contents in the vessels or containers from the atmosphere, our range of septa provide

Loose Septa are designed to serve as replacement septa for Thermo Scientific VOA vials and septa bottles with 24-414 open-top caps.Septa are available in a variety of materials and thicknesses. PTFE Natural Rubber are moderately priced seals for GC and HPLC with good chemical properties. They are ideal for multiple injections due to high resealability, but not as easy to penetrate as PTFE/RR

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.

When separating organic and inorganic compounds for analysis, chromatography vial closures protect compound mixtures from contamination. The caps feature different finishes and septa materials for gas or high performance liquid chromatography applications. Maintain a clean and safe workplace using the spill-free chromatography vial closures available in various sizes and styles to be

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

The septum is suitable for use with all GL 45 sizes of the DURAN® GL 45 bottles from 100 to 20,000 ml. A liquid tight seal is provided when used in combination with the red PBT GL 45 open topped screw cap. Wide temperature usage range from – 50 °C up to + 180 °C. Autoclavable at 121 °C for 15 minutes. Dry heat sterilizable at up to 180 °C.

Axygen® AxyMats™ septa mat is designed to be used on ABI sequencer. Made of research-grade silicone, they can be autoclaved, and following a bleach wash and ethanol rinse protocol, they can also be reused.Septa Mat for ABI Multi-Capillary Sequencing InstrumentFor use with 96 PCR microplates

Supplier: Thermo Scientific. Autosampler vial septa, 13 mm for use with 13-425 threaded caps or 13 mm snap/crimp caps. PTFE disk septa are chemically inert. PFTE/red rubber septa are economical for many GC applications. PTFE/silicone septa are most popular for HPLC and IC applications. Pre-slit septa are easier to pierce with thin gauge needles.

Application. Clear glass, screw top vials with hole-cap PTFE/silicone septa may be used, to contain plant tissue in an experimental study done in order to identify major volatiles emanating from chestnut reproductive plant tissue. [1]
