9mm PP Screw Neck Caps with Center Hole

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.

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.

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.

While most liquid chromatography autosamplers use 12 x 32 mm vials, the most common HPLC vials are 9 mm screw vials. 9 mm screw vials have openings that are large enough for easy pipetting, but the necks (and closures) are still compatible with most autosamplers in use today.

The 2ml 9mm HPLC Autosampler Vials also offers a variety of closures, including crimp/snap or threaded closures. Screw-type closures can also be of different sizes identified by the outer diameter of the vials. If you use an autosampler, choose the 2ml 9mm HPLC Autosampler Vials for your specific equipment brand. 2ml 9mm HPLC Autosampler Vials work with Aijiren autosamplers.

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 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 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.

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.

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.

The 9mm hplc vial provided by Aijiren has a high recovery type, which can effectively recover samples and reduce sample residues. This high recovery 9mm hplc vial is made of extremely inert borosilicate hydrochloric acid glass, which is not easy to react with chemical reagents.

The Autosampler Vial produced by Aijiren is often used in autosamplers. Whether it is Aijiren or other brands of autosamplers, Aijiren Autosampler Vial can be perfectly adapted. It is precisely because of this that Aijiren Autosampler Vial can be so well-known and become A well-known manufacturer of chromatography consumables in the world.

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.

Polypropylene Screw Cap with Septa – Polypropylene screw cap with precision-fit septa provide an evaporation-proof seal. Bi-layer include silicone and PTFE. Silicone septa for multiple injections.

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

The large opening reduces the risk of bent autosampler needles during sampling. When choosing a 2mL Glass Screw Top Autosampler Vials, the product material is of paramount importance.
