Gerstel headspace crimp vials are available in clear glass with 10 mL or 20 mL volumes for standard headspace applications. A 20 mL vial with a thicker neck is available for SPME applications. Twister headspace vials are available for use in Headspace Sorptive Extraction (HSSE). Gerstel headspace crimp caps are 20 mm and made from either

20mm crimp headspace vial is widely used in Headspace and GC, GCMS application. 20mm Aluminum Crimp Cap Seals and Vials ensure that a proper seal is made for this demanding application Vials are manufactured of borosilicate glass and include a write-in patch for sample identification. Caps are made of high quality laquered aluminum, 0.010" thick

High levels of total suspended solids can affect turbidity, increase water temperatures and decrease dissolved oxygen (DO) levels. This can cause the water to heat up more rapidly because the suspended particles absorb more heat and deplete oxygen, which can adversely affect aquatic life.

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.
