Laboratory Bottle 10ml 20ml Screw Headspace Amber/Clear Glass glass Vials with Aluminum cap
10ml 20ml laboratory bottles and vials are commonly used in scientific research and various laboratory applications.
Headspace vials are a specific type of laboratory vials designed for the analysis of volatile compounds in gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS).
It seems you are referring to two types of laboratory vials:
10ml and 20ml screw headspace vials made of either amber or clear glass, with aluminum caps.
1.The purpose of headspace vials is to facilitate the analysis of volatile or gaseous components present in a sample.
2.The septum acts as a barrier between the sample and the headspace above it, preventing the escape of volatile compounds before analysis.
3.Clear glass vials allow for easy visual inspection of the sample.
4.Amber glass vials provide protection against light.
