Apr 8, 2021 · Step 1: Determine Vial Closure Style. Screw Thread Vials. Screw thread vials are typically used for HPLC and LCMS analysis. Screw thread vials do not require additional tools for attaching the cap, nor for removing the cap. Crimp Vials. Crimp Vials are commonly used as a GC Vial for gas chromatography analysis.
Headspace gas chromatography requires headspace vials and caps because they can withstand the pressure from the gas. Chrom Tech has a wide selection of high-quality crimp and screw thread headspace vials available in clear or amber glass with associated 18-and 20-mm headspace closures. 2 ml vials with caps in amber for HPLC and GC

What Types of Test Tubes are Available? • Thin-walled test tubes, medium-walled test tubes, or thick-walled test tubes. • Round-bottom test tubes predominate, others have flat or conical bases. • Rimmed test tubes for easy pouring, or rimless test tubes. • Screw-top test tubes, plain-top test tubes, or test tubes with ground glass sockets.
Thermo Scientific™ 20 mm Headspace Vials, Septum, and Caps Headspace vials are available in clear or amber glass with a round or flat base, a crimp seal with a beveled or square edge finish, or with a screw-thread finish.
The Aijiren Automatic Liquid Sampler (ALS) provides dependable, fast, and precise injections for Aijiren GC and GC/MS systems. The modular design allows this autosampler to grow with your lab. You can start with a 16-vial injector tower then expand to the 150-vial tray and add a second tower for dual simultaneous injections to increase
These vials have a thicker glass wall to withstand higher temperature and internal pressure for the analysis of volatile gas in the vial’s headspace. Headspace vials with 20 mm crimp tops and 18 mm screw tops in sizes ranging from 6 mL to 20 mL are available in clear or amber glass.
Chromatography vials typically have crimp, snap, or screw finishes. Closures may be pre-assembled with septa or the septa purchased separately. Vials with closures are also sometimes sold in pre-assembled sets. Crimp top finishes are used with aluminum crimp seals to create a more permanent closure.

Headspace vial caps are available in a variety of materials including aluminum, bimetal, and steel; headspace vial cap septa are available in PTFE/silicone, molded PTFE/butyl, and high-temperature varieties. Our headspace vial caps come in either 11 mm, 18 mm, 20 mm or 22 mm sizes. Most used headspace vial caps are crimp cap style.
The milled biscuits were added to the 120 mL screw cap glass vial containing a stirring bar (40 × 0.9 mm, 200 rpm). For AA extraction, 10 mL of water were added. The screw cap glass vial was closed and the suspension was stirred for 15 min at room temperature to soak and swallow the solid matrix and facilitate AA extraction (Figure 1, step 1).
