Product Description
Screw-cap headspace vials let you skip the crimper while still running heated, pressurized samples. These 10 mL and 20 mL vials have an 18 mm screw thread finish and rounded shoulders and bottoms for even heating and safer operation at higher pressures.
This listing is for Wheaton catalog number W225287: Screw Thread Headspace Vial, Amber, 20 mL, Case of 100. They are converted from Type I borosilicate glass tubing in clear or amber, the amber helping to protect light-sensitive samples. Pair them with 18 mm magnetic or standard headspace screw caps. Vials are packed 100 per case. Their uniform tubular construction gives consistent dimensions for reliable autosampler handling and sealing from vial to vial. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
