Silicone: Alcohol, DMF, DMSO, hydrogen peroxide, sodium hydroxide: ACN, benzene, chloroform, hexane, HCL, MEK, THF, toluene: Silicone / PTFE: PTFE chemical resistance until punctured, then septa or liner will have compatibility of silicone: PTFE does not reseal after being punctured: Viton® Alcohols, benzene, chlorinated solvents, HF, heptane

The septum is provided with a thin 0.005” PTFE layer laminated to highly pure silicone, and slit through the center for easier needle penetration and to release the vacuum that forms when a large volume of sample is withdrawn from a vial.

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

The septum you choose for your autosampler vial can impact sample evaporation, sample security, needle bending and blockages, and instrument down time. Don’t let the complexities of septa selection slow you down. Use the simple online Aijiren Tech SureSTART Selection Guide to find the right septa and vial for your analysis.

Deactivated Clear Glass 12 x 32 mm Screw Neck Vial with Cap and Preslit PTFE/Silicone Septum, 2 mL Volume, 100/pk. When working with highly polar analytes that may associate with the polar glass surface, chromatographers choose deactivated vials as the effective vial of choice. These glass vials are treated with gas-phase, reactive organosilane

Jul 23, 2020 · By definition, According to the definition, Septa is a circular gasket made of Silicone or silica gel. In HPLC analysis, Septa is usually placed in the Cap of the HPLC Vial to seal the HPLC Vial to ensure that there is no gap between the Cap and the Vial.Aijiren's Septa uses a double-sided material, and the combination of PTFE and Silicone

Closures may be pre-assembled with septa or the septa purchased separately. Vials with closures are also sometimes sold in pre-assembled sets. Crimp top finishes are used with aluminum crimp seals to create a more permanent closure. Choose a flat finish or use a beveled finish for a tighter seal.

Nov 5, 2018 · PTFE/Silicone septa have the chemical resistivity of PTFE until pierced, and then they have the chemical resistivity of silicone. We recommend you choose a product which is designed and tested ...

8-425 HPLC vials with or without Pre-slit Septa . Storage Considerations for Silicone/PTFE: Silicone rubber can readily absorb chemicals from the environment. Care needs to be taken in storing caps prior to use. Recommendations include: Don't store the septa in locations where chemicals vapor is present for prolonged periods.

Mar 31, 2022 · PTFE/silicone septa. PTFE/Silicone is an ideal choice for analyzing volatile organic chemicals. These analyses happen at low concentrations or during operation at higher conditioning temperatures. Store PTFE/Silicone septa in a glass Purepak jar to ensure: 1. minimal background, 2. low permeability, 3. and the best performance of any headspace

Jul 31, 2020 · Needle Gauge: A bigger needle gauge can need more force to get through non-pre-slit septa, which could cause damage to the septa or sample contamination. A pre-slit septum might be the best choice in this situation. Injection Frequency: A pre-slit septa may be more appropriate for applications requiring repeated injections since it can lessen

Jun 13, 2022 · Using a vial with pre-slit septa is ideal if a sample of only a minimal volume is getting injected. It can improve injection-to-injection reproducibility. An example is when the autosampler must process more than 50µL of a sample if the vial is just 2mL. Choosing the right septa is as crucial as choosing the right kind of HPLC vial.
