Jul 31, 2020 · Aijiren offers two types of pre-slit Septa, single slit and cross slit, such a slit can guide the injection needle accurately punctured Septa into the HPLC Vials, without a thin automatic injection broken, or the cushion falls off into the HPLC Vial contaminated sample.
The vials also have high temperature resistance and are suitable for use in temperatures between -50°C to 120°C (although a rapid change in temperature of the products should be avoided). The Performance Level 1 vials are designed to identify those which are suitable for simple routine, testing with limited budget.
Aijiren's 2 mL screw top vials are constructed from Type 1 borosilicate glass, with low metal content, to protect your sample from destabilizing or leaching. Our 2 mL glass vials are available in both amber and clear versions. The associated 9 mm vial screw cap comes with your choice of septa constructed from either PTFE/silicone, PTFE/silicone
12x32mm test HPLC glass vials silicone slit septa A 12x32mm vial is also known as 1.5mL, 1.8mL, and 2.0mL vials by different manufacturers. Microsampling options include using a one-piece vial with fused Get Price 12x32mm chemistry autosampler glass vials silicone/PTFE The vials have a 12mm diameter and a 32mm height. The vials are amber.
Mar 17, 2009 · As the Silicone part of the septa represents 95 per cent of the complete septa thickness, the needle can easily penetrate through the Y-slit for most of the septa’s thickness. Only the 0.05mm thick PTFElamination which is uncut, needs to be penetrated by the HPLC needle itself, but this goes without any problems even for these needles.
PTFE / Silicone septa (T/S) are the most useful for HPLC applications as they have wide chemical compatibility and low extractables (I recommend them for general purpose use) . These area
make PTFE/silicone septa suitable for all types of chromatographic applications. A thin film of PTFE is laminated to the side of the septum that faces the sample to limit exposure of the elastomer to the solvent. PTFE/Silicone septa are ideal for use in most HPLC and GC applications where resealability and purity are critical. Pre-slit PTFE
