9mm Screw Neck PP Cap are Manufactured

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.

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. 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.

The 2ml 9mm Screw HPLC Vials provided by Aijiren can be added with a writing area, which is convenient for customers to mark
samples during experiments and to distinguish samples. Aijiren’s 2ml 9mm Screw HPLC Vials also accept logo customization. If
the customer needs, we can print the customer’s brand logo on the vial. We provide customized services to facilitate customer needs. If you need 2ml 9mm Screw HPLC Vials or customized service, please contact us.

Autosampler vials are available in a variety of sizes, with 2 mL vials being the most common size. During the injection process, the autosampler needle pierces the cap and extracts the desired amount of analyte from the vial. There are different types of vials for chromatography applications.

The non-pre-slit septas help to reduce carryover from vial to vial because the resealing characteristics of the septum act as a squeegee to wipe solution from the outside of the needle. Typically, a non-slit septum exhibits resealing capabilities for a limited number of needle punctures but for long-term storage in the vial, using a new non-punctured septum is best practice.

Chromatography autosampler vials are widely used in chromatography, chemistry, medical and other fields. Autosampler vials are generally made of hydrolytic glass or borosilicate, with various specifications. Different vial mouth designs meet different actual needs.

Chromatography vial is a glass vial used by automatic samplers and headspace samplers such as liquid chromatography, gas chromatography, mass spectrometry, etc. for chromatographic automatic sampling. Its basic requirements are accurate volume, ability to withstand a certain pressure, good sealing performance, and no adsorption to samples.

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.

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

The vial is made of colorless Class 1 A or amber Class 1 B borosilicate glass. The automatic sample vial is produced from high-quality raw materials. It has high-temperature resistance and corrosion resistance. Controlled manufacturing environment quality and service have won the trust of customers.

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.

screw vials are also available in different sizes, and the cap is made of PP for sealing. The glass vial has a maximum capacity of 2ml and has a screw cap. The insert can be used with any autosampler and fits standard or wide-mouth vials.

Although most laboratories have switched to 9 mm screw thread vials for a wider opening while still being autosampler compatible, some labs use 8-425 vials for storing solvents. The standard opening 8-425 vials have more threads per inch, so there is less likelihood that volatile solvents will evaporate over time.

These vials are the preferred choice for modern autosamplers. With a focus on improved sample security and integrity, we now offer innovative 9mm closures and 9mm screw top vials for consistent productivity on every separation.
