20mm Crimp Caps squeeze the septum between the rim of the glass vial and the crimped aluminum cap. This forms an excellent seal preventing evaporation. The crimp cap vial requires crimping tools to carry out the sealing process.

Aijiren polypropylene screw micro vials can be used in most standard gas and liquid chromatography autosamplers. These lightweight, economical vials are made from durable polypropylene which has good chemical resistance.

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.

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.

Snap Vials are manufactured from Type 1 borosilicate glass(Class A, 33 expansion borosilicate glass), available in clear or amber, or from Polypropylene. Snap Vials accept both an Aluminum Snap Seal as well as a Polyethylene Snap Cap. Excellent for short-term storage. Deactivation, MS Certification is also available.

Aijiren provide 1mL 8x40mm Shell Vial Kit. Finding suitability to be used over a wide temperature range, these 1ml Shell vials come extensively tested so as to perfectly match up with the end user demands. Undergoing lab tests for ensuring defined quality standards.

PVDF syringe filters are made of hydrophilic PVDF membrane and a polypropylene overmold housing. Available in 13 mm and 25 mm diameters and 0.22 μm and 0.45 μm pore sizes.

Our 9 mm Wide Mouth Vials and Closures are our recommended screw thread vials. These vials are autosampler compatible and offer a 40% larger opening than 8-425 thread vials, simplifying pipetting and other routine functions. Aijiren Tech offers 9 mm screw thread vials in clear and amber glass, as well as polymeric options and mass spec quality glass.

Empty glass HPLC vial refers to a type of vial specifically designed for use in High-Performance Liquid Chromatography (HPLC) applications. HPLC is a technique used in analytical chemistry to separate, identify, and quantify components of a sample mixture.HPLC vials are made of glass to ensure chemical compatibility and to minimize sample contamination. These vials typically have a capacity ranging from 1.5 mL to 2 mL, although other sizes may be available. The vials have a narrow neck and a screw cap or crimp cap closure system to secure the contents and maintain the integrity of the sample during analysis.

Micro-vials are small containers or vials designed to hold very small volumes of liquid or samples. They are typically used in scientific research, medical diagnostics, and pharmaceutical industries, where precise and accurate measurements of small quantities of substances are required.Micro-vials are commonly made from materials such as glass or plastic, depending on the specific application. They are designed to be airtight and leak-proof to prevent contamination or loss of the sample. The vials often have a small opening or cap that allows for controlled dispensing or extraction of the liquid or sample.
