9mm Screw Neck PP Caps

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.

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.

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.

The Lab Use 9mm 2ml HPLC Autosampler Vial for Supply is a specialized vial designed for high-performance liquid chromatography (HPLC) applications. With a 9mm thread size, these vials ensure a secure and leak-proof seal, preventing sample contamination and maintaining sample integrity during analysis.

9mm Closures are formed by the combination of Cap and Septa. Screw Neck guarantees the tightness of 9mm Closures. Generally speaking, one end of PTFE faces the sample surface, because PTFE is highly inert and difficult to react with chemicals. Aijiren also supports separate orders for Cap and Septa.

Aijiren’s 2ml Glass Vials can be applied in a wide range of fields. Many projects that require chromatographic analysis need to use 2ml Glass Vials, such as environmental analysis, soil analysis, pharmaceutical analysis, food analysis, etc. The aim of Aijiren is to provide high-quality chromatographic consumables for customers of chromatography.

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.

The 9mm 2ml Screw Autosampler Vial for HPLC is a vital component for precise and reliable liquid chromatography analysis. With a capacity of 2ml, these vials provide ample space for sample storage.

Screw Cap Vials are universal. Screwing the cap applies a mechanical force that squeezes the septum between the glass rim and the cap. Screw caps form an excellent seal and mechanically hold the septum in place during piercing. No tools are required for assembly.

Polypropylene screw cap with septum – Polypropylene screw cap with precision fit septum provides anti-evaporation seal. Two layers include silicone and PTFE. Silicone septum for multiple injections. PTFE lining screw cap for organic samples. The screw cap provides an inert airtight seal and holes directly into the sample with a needle.

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.

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.

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.

Aijiren understands that 2ml HPLC vial are as important as chromatography columns or instruments. As a result, Aijiren 2ml HPLC sample vial are designed to meet the highest standards you can expect. So 2ml HPLC vial can be exported to 32 countries.

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.

If the weight, damage, surface inertness, and/or disposal costs of the glass vial are concerned, the vial manufactured from polypropylene is an alternative to consideration. The benefits of polypropylene materials include low extraction rates, compatibility with many solvents, ideal for working with proteins, ideal for ion chromatography applications, ideal for pH-sensitive sample storage, and eliminate the need for inserts during microsampling.
