9mm Silicone and Teflon Septa for Screw Cap

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.

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.

9mm screw autosampler vial is widely used in laboratory chromatographyanalysis. Aijiren as one of largest chromatography consumable supplier, supplies 9mm screw HPLC vial in wholesale price. This 9mm screw vial package can reduce screw vial mouth touch to prevent contamination of sample. At the same time, the package box can be used as a vial rock, it is save the cost. Welcome to inquiry us about chromatography consumable.

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 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.

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.

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.

Chromatography 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

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.

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.

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

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.

Chromatography sample 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.

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

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.

High recovery vials are optimal for manual and automated compound or biological sample applications. High Recovery Vials allow maximum sample extraction without need for separate inserts

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.

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.

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.
