Aijiren screw thread top autosampler vials design is characterized by universal ease of use, especially the use of automated sample introduction systems, so this type of vial is also called an autosampler vial. Aijiren 10mm 2ml hplc auotsampler vial is generally made of high-quality imported expanded borosilicate glass tube. The high cost performance of this material is the first choice for throughput analysis.

The choice of autosampler vials may seem much less important compared to the significance chromatography instruments many laboratories use. However, the wrong choices of HPLC or GC vials, caps, septas and inserts might well lead to lower experiment productivity and reproducibility or even mechanical damage to the autosampler.

The default is 25 pcs/foam box. If you need 100 pcs/carton, please contact the product manager.

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. They fulfill all requirements with regard to tightness and analytical purity for GC as well as for HPLC. Due to the relatively thin septa penetration is safe and easy.

Aijiren vial inserts are the perfect fit for HPLC and GC instrument platforms across a wide variety of applications, including pharmaceutical, environmental, energy and fuels, forensics, materials science, biopharmaceutical, proteomics, and metabolomics.

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 GC  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.

A 2ml snap autosampler vial is widely used in HPLC applications and can be used almost as universal sample vials for autosamplers, including sample vials with automatic operation. The vial features an 11mm snap ring closure, which provides a secure and leak-proof seal. These 2ml snap autosampler vials are recommended for short-term sample storage and non-volatile samples because the seal is not as secure as a crimp or screw thread seal. Vials have a 40% larger opening than standard aluminum seal vials for easier sample filling and to reduce the chance of bent or broken needles during sampling. Compared with crimp top vials, snap vials can be capped and uncapped easily without tools, making it more convenient to use.

Aijiren Tech 20ml gas chromatography vials are manufactured to provide uniform glass thickness which ensures even heat distribution for consistent sampling reliability.

Short Thread Bonded Caps for screw thread vials are available with either an open hole for autosampler use and standard addition or with a solid top for sample storage. Teflon and silicone rubber or ultra-pure silicone are used as raw materials to ensure that the septa are non-toxic; Adhesive-free bonding process, without the introduction of adhesive, the septum retains the excellent resilience performance of silicone rubber or silicone, softer than the septum of the adhesive process, which can provide better needles for the autosampler. protection of. Strict production management ensures product quality. The Bonded Caps with Septa are clean and ready to use without cleaning.

The material of 20ml amber vials is low extractable Borosilicate glass with low expansion rate, high-temperature resistance, high strength, high hardness, high light transmittance, and high chemical stability.

Preassembled polypropylene snap-top closures with a 6mm center hole, including  PTFE/silicone septa. To use with 11mm snap-top vials. Snap caps provide a secure seal, minimizing evaporation even with volatile samples. Snap ring closures N11 should only be used in HPLC, as the punctual compacting pressure of the septum against the vial rim by the four pins in the cap does not achieve the same level of tightness as the evenly applied pressure through a screw thread or by crimping.
