wide opening gas chromatography vials with silicone septa VWR

Special pre-cut septa (silicone layer is slitted but PTFE remains intact) for safe penetration of the sensitive SPME phase with hardly any coring Tested and approved by CTC for their Combi PAL (Gerstel, Atas, Aijiren), also recommended by Aijiren for their A samplers, by Shimadzu for AOC5000 and for PerkinElmer TurboMatrix autosamplers

Wide opening enables easy filling Closures with different types of septa can be supplied with differently coloured caps; blue cap also available with closed top Pre-cut closures for HPLC needles are available, where only the silicone is slitted, but the PTFE remains intact (no concentration changes; no contamination due to impurities extracted

PTFE/Silicone (maximum temperature 250 °C). Use with most organic (until pierced). Not recommended for use with chlorosilanes. PTFE/Thermoseal (maximum temperature 300 °C. An improved grade of silicone septa that can be used at higher temperatures. Affected by many organic solvents. Viton (maximum temperature 315 °C). Resists mineral oil

Gas Chromatography These high performance wide opening SureStop™ screw thread vials are made from superior quality 33 ... Septa, Silicone/PTFE, Ø: 24 mm. UOM ...

Gas chromatography uses helium, hydrogen or other gases to separate, identify, and quantify sample mixtures with reliable results. This technique is widely used in the food, environmental, and chemical industries but also has many other applications.

Vials are available in all capacities, materials like plastic vials or glass vials, and in a variety of colors to meet any collection, storage, or analysis need. Tailor vessels for specific media with various translucent manufacturing and different sterility options for precise test results.

Designed to use separating organic and inorganic compounds for analysis, chromatography vials come in different finishes to guarantee chemical compatibility. Autosampler compatible closures come in different colors, sizes, and septa materials. Offered with a write-on patch, possible identification errors are eliminated.

These high performance wide opening SureStop™ screw thread vials are made from superior quality 33 expansion borosilicate clear (Type 1, Class A) or 51A amber (Type 1, Class B) glass, and meet all US, EU and JPN Pharmacopia standards.

Figure 3 - Typical mass chromatogram of volatile residue in hexane caused by PTFE/silicone septa: a) hexane extract of a piece of septum; b) vial septum was punctured once by a syringe to sample 1 μL hexane for GC analysis; c) hexane in the last vial was reanalyzed after 3 days; and d) analyzed immediately after 100 μL hexane was added from one vial to another (the septum was punctured 10

These vials are built with Advanced Vial Closure System (AVCS). This innovation not only prevents septa push through, but provides a stop point for the cap to prevent over- or under-tightening and provide an optimal, consistent seal every time. Vials are made from superior quality 33 expansion borosilicate clear (Type 1, Class A) glass, and meet all US, EU and JPN Pharmacopia standards.
