32*12 mm, 2ml, screw neck, It is dimensionally equivalent to 11mm crimp top vials and 10-425 screw vials. The 9mm screw vials can be used in any autosampler which used 11mm crimp top vials and 10-425 screw vials. Compared to 11mm crimp top type, the 9mm screw one can be much applied as hand removing convenient.

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 clear glass vial inserts, polypropylene vial inserts, and high recovery vials ensure you extract the maximum possible amount of your precious sample.

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.
