9mm PP Screw Neck Caps with Center Hole

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.

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 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 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.

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.

Screw cap vials are a practical packaging solution for sample-size health, beauty, and pharmaceutical products. Glass screw cap vials are impermeable and don’t undergo chemical leaching, so your products stay pure. Uses for Screw Cap Vials. Use glass screw cap vials to package sample products or as full-size product packaging options.

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

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 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.

Aijiren focus on improving the safety and integrity of our samples. Aijiren provide innovative 9mm thread caps and 9mm 2ml Hplc Screw Vials to ensure consistent productivity in all separation processes. These vials are the best choice for the latest autosampler. Standard open screw vials are made of borosilicate glass with a maximum filling volume of 2ml.

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.

Aijiren’s 9mm Screw Neck Autosampler Vial is one of Aijiren’s most popular products. The screw neck and 2ml capacity are very compatible with the specifications of the autosampler, especially Aijiren’s 100pcs/pack, which is very convenient for customers to use. It is well received, has strong stability and is not easily affected by other reagents.

The 0.3ml PP Clear or Amber Micro Vial with a 9mm Screw Neck is a versatile and compact solution for laboratory sample storage and analysis. These micro vials are made of high-quality polypropylene (PP) material, ensuring excellent chemical resistance and sample protection. Available in clear or amber options, they offer visibility and light protection for different sample types.

Capacity: 1.5/2ml
Temperature: -60—200℃
Material: bottle (domestic borosilicate); gasket (Teflon/silicone); lid (polypropylene)
Color: bottle (transparent/amber), cap (blue)

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.

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

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 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.

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.

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.
