Description

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.

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.

Aijiren Tech 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 OEM instrument manufacturer’s specifications. Aijiren Tech vials are available in 6ml, 10ml, 20ml versions with Screw and Crimp type.

18mm Screw Headspace Vial Features

1. 20ml precision screw headspace vial, 18mm, round bottom, top space vial, strong adsorption

2. The 20ml precision threaded headspace vial is used for the threaded vial (10ml+20ml) and magnetic screw cap of CTC and TriPlus autosampler.

3. It is convenient to use and does not require any additional tools such as capper and decapper.

4. The sample is available on site Transfer, no need to transfer samples in the laboratory.

5. The precise screw thread ensures the air tightness between the vial and the cap.

6. The magnetic screw cap can be widely used in various SPME and headspace analysis.

7. The round bottom vial is stronger, has higher pressure tolerance when the sample bottle is heated, and is easier to slide into the heating hole.

Advantages

1. Material: USP1, Borosilicate Glass

2. Box packaged tpo minimize sample bottle damage.

3. Manufactured under strict quality, which ensures dimensional consistency from lot-to-lot

4. Suitable for headspace analysis of volatile solids and gases.

5. Store volatile samples to prevent sample evaporation

6. High temperature resistance and corrosion resistance

7. Mainly used in gas chromatography analysis for headspace analysis.

8. No risk of incorrectly sealed vials as is the case with crimping

9. More convenient to close and open, especially as magnetic crimp caps are very hard to crimp

10. Lower coring and protection for the needle due to thinner septa

11. Universal use for Headspace and SPME due to thinner septa

12. Special pre-cut septa (silicone layer is slitted but PTFE remains intact) for safe penetration of the sensitive SPME phase with hardly any coring

13. Tested and approved by CTC for their Combi PAL (Gerstel, Atas, Agilent), also recommended by Agilent for their G1888A samplers, by Shimadzu for AOC5000 and for PerkinElmer TurboMatrix autosamplers 

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, they 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 vial 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.
