10-20mL 18mm Screw Thread Headspace ND18 Supplier
10mL & 20mL screw neck ND18 rounded bottom headspace vials with matched 18mm magnetic precision screw metal caps, 17.5mm PTFE/silicone septa. Aijiren Tech screw headspace vials are manufactured to provide uniform glass thickness which insures even heat distribution for consistent sampling reliability. All Aijiren Tech headspace vials meet or exceed the OEM instrument manufacturer’s specifications. Aijiren Tech screw GC vials are available in 10ml, 20ml versions. Headspace vials are a kind of laboratory vials for top space analysis, with the features of high-temperature resistance and corrosion resistance. 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 vaporize them at the top. In this process, 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.

Feature
1. The material of screw 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 are suitable for headspace analysis of volatile solids and gases.
2. The Aijiren screw headspace vial has a beveled neck for safe sealing, uniform glass thickness for uniform heating distribution and stability, and a sturdy design that is easy to use.
3. Mainly used in gas chromatography analysis for headspace analysis.
4. More convenient to close and open, especially as magnetic crimp caps are very hard to crimp
Application
The vials are preferentially used on instruments: CTC PAL, Varian, Gerstel, Atas, Shimadzu, and Agilent.
Matching bottle cap and gasket
The 18mm septa uses only the highest quality materials to ensure proper function, and is especially suitable for gas chromatograph applications, ensuring that the septa will not fall into the sample vial during sample injection. The septa are made of PTFE/silicone fusion, are made of TFE/silicone fusion, and have excellent inertness, and can be used for multiple injections. The thickness of the septum is 1.5mm.
The screw headspace series vials caps combine innovation with time-saving convenience, precise manufacturing tolerances, and a controllable manufacturing environment. The bottle cap produced by this patented method truly combines the septum and the cap at the molecular level to avoid excessive evaporation and keep the sample bottle properly sealed.
