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.

The classification of HPLC autosampler vials is generally done based on the diameter of the vial body, vial height, and thread finish.Our 2ml Screw HPLC Vials are the perfect fit for HPLC and GC instrument platforms across a wide variety of applications.

Autosampler vials for HPLC are generally grouped depending on the diameter of the vial, the height of the vial, and, the thread finish. Both clear glass and amber glass are highly inert.

Polypropylene vials are an economical alternative to glass for some applications. The vial is primarily constructed from high-quality, durable polypropylene or polymethyl pentene (PMP). This plastic is typically chosen for its chemical resistance, inertness, and transparency. Polypropylene is the most popular plastic material. Polypropylene vials have heat resistance of up to 135 degrees Celsius and are commonly used in chromatographic experiments. PMP has higher heat resistance – up to 175 degrees Celsius – and is transparent, increasing the sample’s visibility inside the sample bottle. The vial typically has a standard 9mm outer diameter, making it compatible with a wide range of autosampler systems commonly used in laboratories.

The vial has an outer diameter of 9mm and is designed especially for use with Agilent’s and other rotating or robotic arm samplers. The vial features a short thread design with threads on the neck of the vial. This design allows for a secure and reliable closure when used with compatible screw caps or septa. Caps are made of high-quality polypropylene to exact manufacturing tolerances and lined in a controlled manufacturing environment. Available cap colors include yellow, red, green, and blue. Our septa use only the highest quality PTFE and silicone to ensure proper function and can be pre-slit to ease needle penetration.

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.

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).

Founded in 2007, Zhejiang Aijiren, Inc.15 years export experience, exprot to more than 70 countries, 2000+ customs around the world; IS0, GMP & Bureau Veritas certificated, this is how we keep good quality and competitive prices for global valued customers.

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; to ensure excellent functions, it is particularly suitable for gas chromatography, and to ensure that the septum does not fall into the sample vial during the injection process.
The adhesive-free bonding process is used to combine the polytetrafluoroethylene membrane and the silicon rubber or silicone bond together to maintain the excellent characteristics of the two materials. The polytetrafluoroethylene layer of the composite septum is in contact with the reagent. It is chemically inert and resistant to acid, alkali, temperature, and adhesion. It does not work with concentrated acid, concentrated alkali, or strong oxidants even at high temperatures. At the same time, the elasticity of silicone rubber or silicone layer can ensure sealing performance.

Aijiren has own R&D Center and Quality Controll Center to keep products in high quality. All materials are produced at 100,000 grade clean room. Passed ISO9001:2015 quality management system certification, RoHS compliance can also be provided.

There are many differences between butyl and natural rubber. The main advantage is that butyl rubber has better chemical stability and aging resistance than natural rubber. It has the elasticity of natural rubber and does not contain protein ingredients, but it does not have butyl. Chemical inertness and aging resistance

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.

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 are suitable for headspace analysis of volatile solids and gases.

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 an autosampler vial. And this sample vial is extremely compatible.The 1.5ml sample vial we usually say is the 2ml volume sample vial.

Aijiren COD Test Tube is made of borosilicate glass, which can reduce pH changes and pollutants that may be leached from soda lime glass. The glass digestion test tube can be used for analysis at temperatures higher than 130 degrees Celsius. It is manufactured from laboratory storage for a variety of general purposes and can hold almost anything. The SEPTA is made of PTFE silicon rubber gasket, which has a strong sealing performance and can resist various chemical corrosion. Used for municipal wastewater testing; industrial wastewater and process control testing; and environmental water testing. The used COD Tubetests contain strong sulfuric acid and other chemicals, so reagents must be handled carefully. The contents of the pipe should be disposed of in accordance with the requirements of local authorities.
