EPA VOA Vials Supplier

HPLC autosampler vials  are generally categorized by vial diameter, vial height, and thread finish. Clear glass and amber glass have similar inert properties. Amber glass is used to protect sensitive samples from UV light. Markings on the vials provide sample identification information. Autosampler vials can be used to inject samples from an autosampler.

High recovery vials are optimal for manual and automated compound or biological sample applications. High Recovery Vials allow maximum sample extraction without need for separate inserts

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.

All of Aijiren vials are excellently fitted for autosamplers and have good chemical compatibility and super cleanliness. The crimp top sample vial is the most commonly used gas sampling vial on the market at present. 2ml volume sample vial especially suitable for laboratory use. At the same time, some vial bottoms are designed with round bottoms, so that it has a flat bottoming function and compatibility with automatic sampling equipment.

Aijiren Crimp Top vials are excellently fitted for autosamplers and have good chemical compatibility and super cleanliness. The crimp top sample vial is the most commonly used gas sampling vial on the market at present. 2ml volume sample vial especially suitable for laboratory use. At the same time, it has a flat bottoming function and compatibility with automatic sampling equipment.

Aijiren strongly recommends to use only ready-made sealing caps, whose lining matches the bottle cap completely, and has been automatically inserted under strict sanitary conditions.

The Crimp Vial produced by Aijiren has a standard 11.6x32mm shape and is compatible with 11mm aluminum sealing caps. Hand Crimper is required for crimp sealing and Decrimper for unsealing. Aijiren provides supporting 11mm Hand Crimper and Decrimper, which are easy to operate and well sealed.

11mm crimp vial is a FDA “white listed” materials,USP VI-certified compound. It can be resealed after multiple punctures. There is no flash or parting line. Various composite hardness testers are provided. Easy to puncture. Customized design to suit each application design. High capacity supply capacity , A wide range of sizes.

The 4ml screw neck glass vial produced by Aijiren is often used in Autosampler. The 4ml 13mm opening is convenient for automatic injection needle injection. The Cap has a center hole. PTFE and Silicone are compounded on both sides to ensure that one side of PTFE faces the reagent inside Vias, ensuring that the stability of the reagent is not destroyed.

One piece polypropylene cap and membrane are also available. These pierceable screw thread caps are designed for one time use and reduce sample preparation time as there is no cap and seal to assemble.

“Aijiren Vials have a standard 11.6x32mm profile and are compatible with convenient 11mm snap cap or aluminum seal closures
The “Step” design ensures proper centering of limited volume inserts, eliminating missed injections
Aijiren Vials have a 40% larger opening than standard aluminum seal vials for easier sample filling and to reduce the chance of bent or broken needles during sampling”

High recovery Vials are manufactured from heavy wall, low extractable, borosilicate glass providing excellent chemical resistance and durability during packaging and transportation.

The 150ul, 250ul, and 300ul Micro Inserts for HPLC Autosampler Vials are essential accessories designed to enhance the functionality of HPLC sample vials. These micro inserts are made of high-quality materials, such as borosilicate glass, providing excellent chemical resistance and minimizing sample contamination.

2mL Amber Glass Screw Top Autosampler Vials are available in a variety of neck finishes and opening diameters. Large mouth or wide ID vials have approximately a 40% wider mouth opening than standard opening vials. The large opening reduces the risk of bent autosampler needles during sampling. When choosing a 2mL Amber Glass Screw Top Autosampler Vials, the product material is of paramount importance.

Snap caps provide a secure seal that minimizes evaporation, even with volatile samples. Snap caps are often more convenient than crimp caps as they can easily be applied and removed by hand. An audible click ensures a secure seal has been formed and that the cap is correctly aligned. Snap/crimp vials can be closed with either snap caps or crimp caps.
