1.5ml 9mm Screw Neck Vial for automatic samplers is made of low metal type 33 and 51 COE borate glass to prevent sample instability or leaching. By selecting the cap and pad, we provide the best sealing solution for the sample.

PTFE-lined screw cap for organic samples. Screw caps provide an inert, airtight seal and direct puncture-access to samples with a syringe needle.

The Lab 9mm 2ml Screw Top HPLC Autosampler Vial features a precision-engineered design, ensuring a secure and leak-proof seal. It is compatible with various autosamplers, making it a versatile choice for HPLC applications.

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.

9mm screw thread caps, septa, and vials are designed especially for use with Aijiren’s and other rotating or robotic are samplers

Short Thread Caps with Septa for 9mm 1.5ml HPLC Vial often come with multiple septa options to accommodate different analytical requirements. Depending on the specific application, researchers can choose from various septa materials, such as silicone, PTFE, or bonded septa, to optimize sample compatibility and performance.

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.

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.

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 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.

With its 9mm screw thread design and capacity of 1.5mL, this vial makes for easy handling and integration into autosamplers. Ideal for applications requiring limited quantities. The vial comes equipped with various finishes and closure options, such as screw caps and snap caps, so researchers can select their ideal choice according to their unique research needs.

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 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.

Polypropylene caps are known for good impact strength, cost effectiveness, and pliability. They can be remelted after they are formed. Aijiren Polypropylene cap is widely used in chromatography analysis.

 9mm Screw conical micro-vial for lab chromatography experiment, the micro-vial size is 11.6x32mm.  High quality glass vial for HPLC/GC analysis. 0.3 ml clear or amber  glass micro insert fixed in 2ml glass vial.

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.

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
