The classification of HPLC autosampler vials is usually based on the diameter of the vial body, the height of the vial and the thread finish. Clear glass and amber glass are similarly inert. Amber glass is used to protect sensitive samples from UV rays. The mark on the vial is useful for sample identification information.
8-425 screw caps and vials are usually combined with Shimadzu, Spectra-Physics, Varian and other autosamplers. The sample bottle is made of transparent A type 1 type A or amber type B type B transparent glass, and has a sticker for sample identification.
The 9 mm wide opening amber glass screw MS certified sample bottle is made of high-quality 33 expanded borosilicate clear glass (Type 1, Type A) glass, and sample bottles in assembled and non-assembled kits are available. For LC/MS, GC/MS and chromatography high sensitivity applications, please use certified clean, low particle, low background vials.
The 10mm Screw Neck Vial has a wide aperture of 10mm, which is convenient for the automatic injection needle to take samples. It is larger than the opening of the 9mm screw vial. If the sample is relatively rare or precious, you can consider using Micro-Insert and micro-insert Made of inert glass, effectively saving samples.
The 2mL amber glass screw-top autosampler vial has a variety of opening diameters to choose from. The caliber of large-caliber or wide-inner-diameter sample bottles is 40% larger than that of standard-caliber sample bottles. The large opening reduces the risk of the autosampler needle bending during sampling. When choosing 2mL amber glass screw-top autosampler vials, the product material is critical.
