laboratory chromatography consumable supplier

The Crimp Top Chromatography Vial is the most commonly used gas sampling vial on the market at present. Features of crimping top-quality sample bottles: Strict quality assurance provides dimensional consistency between batches, optional ceramic writing points with filling marks can be selected, and they are certified and fully compatible with autosamplers.

Micro Insert is used to ensure the most accurate and reliable analysis of your lab samples. Micro-inserts are manufactured of clear glass. Micro inserts, when used in conjunction with autosampler vials, allow for maximum sample recovery and easier sample removal because the conical shape decreases the surface area inside the vial.
Micro inserts can be used with screw tops, crimp tops, or snap-top vials. All conical styles of inserts are offered with the traditional pulled point as well as the improved mandrel point. Pulled point inserts are more economical, but mandrel point inserts provide a more pointed and uniform tip that enables better sample recovery. Micro-inserts can be used on all 1.5ml vials. Effectively relieves the pressure of the syringe. PolySpring inserts are self-aligning.

Chromatography septas can be pre-slit. A pre-slit septum is an ideal choice in applications requiring 20% or more of the sample injection each time from the vial so that suction is avoided. The slit allows ambient gas to equalize the gas in the vial so that a vacuum is not created in the vial from the tight seal around the needle. If coring or clogging from a narrow needle or needle deflection from highly durable septa material is a concern, then choosing a pre-slit septum is a better choice.
A PTFE/Silicone with a slitted septum allows for easier needle penetration as well as to release the vacuum that forms when a large volume of sample is withdrawn from a vial. This septum provides chromatographic characteristics similar to that of a septum without a slit except that the ability to withstand exposure to aggressive solvents is slightly lessened. Pre-slit septa are highly recommended for improving injection-to-injection reproducibility with autosamplers withdrawing greater than 50µL of sample from a 2mL vial, due to possible cavitation (vacuum).

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 a 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.

Aijiren 18mm 20ml Screw Headspace Vial is a high-quality laboratory glassware designed for gas chromatography analysis, featuring a robust round bottom for withstanding high pressures during heating and a precision screw-thread closure for secure sealing.

GC (gas chromatography) and GC-MS (gas chromatography-mass spectrometry) are two analytical techniques commonly used to separate and identify volatile compounds.

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.

2ml Amber Screw HPLC Vials, caps, septa, and inserts working as a whole to prevent sample degradation and loss of samples caused by evaporation. Screw thread closures N9 (9mm) 2ml vials and closures are universally suitable on most autosamplers, convenient in handling and available in a broad selection of different cap colors and septum materials.

Crimp Vials squeeze the septum between the rim of the glass vial and the crimped aluminum cap. This forms an excellent seal preventing evaporation. The septum stays seated during piercing by the autosampler needle. The crimp cap vial requires crimping tools to carry out the sealing process. For low volume settings, manual crimper tools are the choice. For high volume settings, automated crimpers are available.

Advances in glass vial manufacturing now produce the type of threads that are needed to properly seal the vial and cap under pressure, producing a Screw Top Headspace System that works well together.
