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 offers proven autosampler vials and consumables for the chromatographer. The standard opening 2ml clear hplc vials have more threads per inch, so there is less likelihood that volatile solvents will evaporate over time.

Crimp caps squeeze the membrane between the edge of the glass bottle and the crimped aluminum cap. This creates a good seal and prevents evaporation. Crimp cap vials require a hand crimper tool to perform the sealing process.

The Hand Decrimper is typically designed to work with two common crimp cap sizes, which are 11mm and 20mm. These sizes correspond to the diameter of the crimp caps, indicating their compatibility with specific vial sizes. This tool is typically made of durable materials such as stainless steel or high-quality aluminum. These materials are chosen for their strength and resistance to corrosion, ensuring long-lasting performance. The decrimping features a handle, often designed with ergonomic considerations for comfortable and efficient use by laboratory personnel. The handle provides a firm grip for precise control during the decrimping process.

In HPLC analysis, the particle size of the chromatographic column packing is small and it is easy to be blocked by impurity particles. Therefore, samples and solvents need to be filtered in advance to remove particulate contaminants and protect the instrument. Ion chromatography, which is commonly used in environmental analysis, also requires that no inorganic pollutants be introduced in sample pretreatment. Syringe filters can be used in HPLC analysis and IC analysis to filter sample solutions, which is an important step in the sample pretreatment process.

Aijiren laboratory 500ml media bottles are widely used because of consistent performance & better quality. The PP cap and pouring ring of the Aijiren 500ml media bottle can be autoclaved to 140°C.

Snap Cap Vials are an extension of the crimp cap system of sealing. A plastic cap is stretched over the rim of the vial to form a seal by squeezing the septum between the glass and the stretched plastic cap. Plastic has memory and wants to return to the original dimension. This tension in the cap to return to its original size is the force forming the seal between glass, cap and septum. The advantage of a plastic snap cap is no tools are required to assemble. The snap-top cap is a compromise sealing system.

These polypropylene caps have excellent sealing characteristics and offer good chemical resistance including acids, alcohols, alkalis, aqueous products, cosmetics, and household oils. Polypropylene Hole Caps are known for good impact strength, cost effectiveness, and pliability. Septa sold separately.Polypropylene hole caps are available preassembled with separate septa or without septa. We also feature polypropylene hole closures with bonded septa to provide assurance that the septa will not slip away from the cap while injecting.

Aijiren screw thread top sample 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 a autosampler vial. And this sample vial is extremely compatible. The 1.5ml sample vial we usually say is the 2ml volume sample vial. The design of Aijiren screw thread top vials are developed from Europe and the United States, and the design feature is easy to use, especially the use of automated sample introduction system. Aijiren screw thread top vials also known as autosampler bottles.

500ml media bottle with Screw Cap offered are mechanically strong, chemically resistant, and are provided with plastic Pouring rings for drip-free operation.

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).

Teflon and silicone rubber or ultra-pure silicone are used as raw materials to ensure that the septum is non-toxic; the glue-free bonding process does not require the introduction of adhesives, and the septum retains the excellent resilience performance of silicone rubber or silicone, which is better than the glue-based process The septa are softer.

The 11mm crimp top chromatography vials is generally broken down into low boron and chromium, but the difference is that the content of boric acid and the physical and chemical properties of the glass are also different. Aijiren offers 11mm crimp top chromatography vials in the boric acid glass.
