Rated 4.8/5 based on 381 customer reviews


- The 18 mm screw-necked magnetic screw-sealed vials for CTC are new to the market for headspace where crimped necks predominate. However, especially for magnetic caps that are difficult to press, the screw seal is a convenient alternative. - Vials are preferred for instruments: CTC PAL, Varian, Gerstel, Atas, Shimadzu and Aijiren.  

18mm Screw Headspace Vial Features

The screwed interface technology is more convenient and easier to open and tighten. Samples can be removed in the field, eliminating the need for disassembly in the laboratory; particularly suitable for use with the CTC Combi PAL, TriPlus and Shimadzu AOC5000 or other similar instruments. The center opening is designed for both SPME and headspace analysis, and provides sufficient magnetic area for transferring sample-filled vials.
