PTFE/Silicone Septa: (T/S) High quality, pure silicone is laminated to 0.005” thick PTFE to give a pure, highly inert septum with excellent resealing characteristics even after repeated punctures. PTFE/Silicone septa are the preferred product for use in most HPLC and GC applications where resealability and high purity are critical.

A specially moulded seal with a PTFE insert. Sealing surface of Butyl and PTFE affects a more positive seal than non-PTFE-faced septa. Ideal choice for temperatures below 125°C. Good sealing characteristics, excellent resistance to most solvents with reduced coring and high puncture tolerance. PTFE provides increased chemical resistance.

Septum Selection Guide Septa for use with general chromatography vials, liquid injection 2-056 PTFE/Natural Red Rubber PTFE Natural Red 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.

PTFE disk septa A solid disk of 0.010” thick pure PTFE offers superior chemical inertness against the most aggressive solvents. The thin membrane allows for penetration by most normal gauge metal HPLC needles. PTFE septa are not resealable and should not be used with highly volatile solvents, short cycle times or multiple injection methods.

226-54128-01. Description: 1.5mL ND11 Gold magnetic crimp cap, Silicone white/PTFE Red, ultra clean, 100/pack. Learn More. Product Part. 11mm Silicone white/PTFE Red septum, 1.3mm thickness, 45° shore A, 100/pack.

On the other hand, butyl rubber–PTFE septa are mechanically hard and more resistant to the absorption of the constituents of a sample, and it is stable up to 130°C (12, 14). Kolb et al. showed that in using silicone–PTFE rubber septa, 69% of acetone and 89% of dichloromethane were lost, while in butyl–PTFE rubber septa, the losses were

VOA vials for samples with solid or semi-solid matrices (e.g., sludges) should be filled according to the guidance given in the appropriate 5000 series sample introduction method (see Table 4-1) to be used. When 125-mL wide-mouth glass containers are used for high-concentration samples only, the containers should be filled as completely as

The samples were weighed 1 g for solid matrix sample and 5 g for semi-solid or liquid matrix sample into chilled 20 mL headspace vials. Then it is mixed with 9 mL and 5 mL of HPLC grade water each. After sealing with aluminum cap using crimper, the vials are stored in 4 °C until analysis.

Mar 31, 2022 · PTFE disk septa. A solid disk 0.010″ thick, our PTFE stands better than the most aggressive solvents. At least when it comes to chemical inertness. Most standard gauge metal HPLC needles can penetrate the thin membrane. Do not use PTFE septa with the following because you can’t release PTFE septa: 1. volatile solvents, 2. fast cycle periods,
