    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 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 OEM instrument manufacturer’s specifications. Aijiren Tech screw GC vials are available in 10ml, 20ml versions.

    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. 

    Available in clear and amber USP1 borosilicate glass with screws and crimp top. 

    The round bottom vial distributes the internal pressure generated under the high temperature of the glass surface, and it is easier to handle the vial being lifted from the tray by the robot arm. 

    The screw-head empty vial has 18mm Magnetic cap, which is suitable for autosampler using magnetic transportation, while crimping the top bottle to be used with aluminum cap

    The 18mm Screw Neck Vials with Magnetic Screw Seals for CTC is novelties in the crimp neck dominated Headspace market. However, especially for the hard to crimp magnetic caps, screw closures are a convenient alternative.

    The vials are preferentially used on instruments : CTC PAL , Varian, Gerstel, Atas, Shimadzu, Agilent.

    The caps with an aluminium skirt and a magnetic central disk, are easy to crimp and decap.

    18mm Screw Headspace Vial 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 series bottle 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.
