Screw cap vials are universal. When screwing on the cap, a mechanical force is applied that compresses the septum between the rim of the vial and the cap. Screw closures provide an excellent seal and mechanically hold the septum in place during piercing. No tools are required for assembly.

The steep conical High recovery interior bottom provides exceptional downward drainage while allowing maximum retrieval of contents by syringe. High recovery Vials are perfect for specialty pharma, biotech, pharmaceutical and diagnostics packaging applications.

The staff in the picture is disassembling the assembled 9mm Screw Neck Cap with Septa. These are 9mm Screw Neck Closures randomly selected from different machines. Since Aijiren produces more machines, many samples need to be checked. Solution to check whether Septa and Cap are damaged, if they are not sturdy, Septa may fall off or fall off easily. Aijiren’s strict quality inspection guarantees the quality of the product.

The Screw Caps that are inlcuded with this kit are knurled on the sides for excellent gripping and comfort when applyting to the vial. The silicone rubber / PTFE septa used were designed to provide the right amount of resistance to autosampler needles during the injection process so that they penetrate the vial properly without damaging the septa or the injection needle. Too much or too little resistance to the needles can damage the septa, compromise resealing, cause needle blockage from coring of the septa material and even damage your autosampler. These septa perform even when using a wide range of needles: fine, blunt or even dull. Low sample or solvent evaporation performance even after multiple injections have been observed when using aijiren caps.

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.

Screw thread vials and caps provide low evaporation, reusability, less hand injury during manipulation than crimp seals and require no special tools. All screw threads vials and caps are differentiated by their thread finish as defined by the Glass Packaging Institute, GPI. For screw thread vials, a two part number is assigned. For example, 8-425 neck finish represents a vial with a diameter of 8 mm across the outside of the threads and a thread style of 425. Screw thread vials and caps are more expensive than crimp seals.

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.

The 9mm 1.5ml Short Thread HPLC Vials exhibit excellent chemical compatibility, making them suitable for a wide range of sample matrices and analysis methods. They can withstand exposure to organic solvents, acids, bases, and other chemicals commonly used in HPLC analysis. This chemical resistance ensures sample integrity and reliable analysis results.

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.

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

High recovery vials offer precision vials made from low expansion borosilicate glass and designed with a unique interior bottom, solid glass vial of a Microliter-Vial with inner cone, allowing for maximum retrieval of contents by a syringe.
