hplc vial septa

Aijiren uses Silicone and PTFE to produce Septa suitable for Autosampler Vial. Aijiren will compound PTFE and Silicone together in a binder-free compounding method. This Septa is softer and suitable for automatic injection needle puncture. Before laser cutting, there is a process, which is to dry in the dryer to dry the moisture in the raw materials, so as to ensure the texture and application of Septa.

Aijiren presses Silicone and PTFE composite into the picture, and cuts them into rectangular sheets of similar size. Because PTFE is easy to curl and deform, the raw materials in the picture are all curled. Wait for it to enter the dryer to dry the moisture. Keep it level. Aijiren uses a mechanical laser to cut Septa, and guarantees the integrity and chemical nature of Septa.

The Septa produced by Aijiren is suitable for Autosampler Vials. Septa is to help Autosampler Vials to seal. The design of Cap with Septa facilitates the sampling of autosamplers. Aijiren, as a manufacturing enterprise, also requires Autosampler Vial accessories, Cap with Septa. It is produced carefully, using first-class equipment and exclusive craftsmanship. In the picture, Septa is drying.

Aijiren is a production-oriented enterprise with its own production plant and production workshop. Aijiren is committed to producing Autosampler Vial and its supporting Cap with Septa. Aijiren uses high-quality raw materials to produce Septa. The raw materials are free of impurities and pollution. They are processed in a dust-free workshop. Customers can buy with confidence, Aijiren supports factory inspection, welcome to Aijiren.

Aijiren’s 8mm Septa is made of Silicone and PTFE raw materials. Aijiren cuts Pre-slit on Septa for the convenience of customers. The pattern is a font and a cross. The cross-shaped pre-slit septa is the best. It is convenient for the automatic injection needle to puncture. If the customer uses a blunt needle, you can consider buying a cross-type pre-slit septa.

As a factory specializing in the production of chromatographic consumables, Aijiren has hundreds of workers for production, especially Septa. Aijiren has exclusive septa composite technology, so the requirements for the workers in the septa workshop are very high. The workers in the picture are using cutting machines for Silicone and PTFE composite material for cutting work.

The Silicone/PTFE Septa produced by Aijiren uses high-quality raw materials and an exclusive compounding process. This process does not require any adhesives to compound Septa and Silicone to achieve no cracking, no falling off, and a perfect fit for autosampler vial and antosampler.

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.

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 polypropylene caps produced by Aijiren are known for their good sealing effect. There are two types of caps, which are used to store samples in a sealed state and have a center hole to facilitate sampling with an autosampler. Aijiren polypropylene bottle caps are widely used in chromatographic analysis and are often used with screw vial.

8-425 screw caps and vials are usually used in combination with Shimadzu, Spectra-Physics, Varian and other autosamplers. The vials are made of transparent type A type 1 type A or amber type B type B clear glass, and contain Adhesive label for sample identification.

HPLC sample vial Septa is one of the most important part in chromatography consumable. Septa for HPLC has high temperature resistance and corrosion resistance. Quality and service in a controlled production environment is trusted by customers. The Caps are made of high quality polyproylene to exact manufacturing tolerances and lined in a controlled manufacturing environment, The color of the #HPLCvial cap can be customized according to customer needs. Aijiren’s septa use only the highest quality materials to ensure proper function and can be pre-slit to ease needle penetration.
