cheap headspace vials

This is referring to the screw-thread caps (18 mm) and crimp caps (20 mm) for 10 mL headspace vials.We don’t just recommend screw cap headspace vial or crimp cap headspace vial by “feel” or price, running a little experiment to compare the performance of the two kind of headspace vial caps.

A headspace vial is used in the process of top gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to evaporate them at the top. Since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial.

Headspace vials are made of Aijiren’s borosilicate glass. The 18 mm screw-neck headspace vials with magnetic screw seals for CTC are new in the headspace market where crimped necks dominate.

Headspace vials are common consumables generally used in gas phase experiments.  Headspace vials have different capacity specifications, including 6ml, 10ml, 20ml, etc. Use a standard sample vial to ensure sufficient headspace. Usually, the reserved volume should be at least 50% of the sample volume.

Headspace vials can withstand the higher temperatures and internal pressures required for volatile gas analysis. With very low metal content, extractables and leachables, they meet high standards to meet your regulatory requirements. These headspace vials have been specification certified for physical dimensions and autosampler compatibility.

Headspace vials are common consumables generally used in gas phase experiments. Headspace samples are usually prepared in vials containing sample, dilution solvent, matrix modifier and headspace.

The headspace sample vial is used for the headspace analysis, especially for the volatile samples. The cap of the headspace sample vial must be properly and tightly pressed so that it will not affect the use of automatic instruments during the operation.

A headspace vial is used in the process of top – gas chromatography. The material of Headspace Vials is low extractable Borosilicate glass with low expansion rate, high-temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. Headspace Vials suitable for headspace analysis of volatile solids and gases.

Headspace vials are made of Aijiren’s borosilicate glass. You can choose from clear or amber colors. Screw-threaded headspace bottles have an average wall thickness of 1.25 millimeters, providing greater reliability as internal pressure increases. The screw headspace vials with 18 mm magnetic caps are suitable for autosamplers that use magnetic transport, while the crimp headspace vials can be used with aluminum caps.
