9mm Screw Closures

Aijiren produces headspace vials for the convenience of gas chromatographic analysis. Gas chromatographic analysis requires heating and other methods to vaporize the liquid in the vial and extract gas for detection and analysis through an automatic injection needle. Gas chromatograph requires the vial to have good airtightness and heat resistance. With strong stability and large capacity, the crimp top headspace vials produced by Aijiren perfectly meet these conditions.

The worker of Aijiren shown in the picture is inserting a 22mm Silicone/PTFE Septa into a 24mm Screw neck Cap. The worker wears finger cots and holds a tool to press harder to consolidate the tightness of the Cap and Septa. Since Aijiren’s automated merging of Cap and Septa machines is only suitable for the closure of 2ml autosampler vial, this large-volume closure requires manual combination by workers. Aijiren uses a dust-free workshop for production and packaging, so customers can be completely assured of hygiene issues.

24mm Silicone/PTFE Septa is matched with 24mm screw neck cap, suitable for 24mm screw sample storage vial. Aijiren has an exclusive production technology that can compound PTFE and Silicone without adding any adhesives, so Aijiren’s Septa is soft and not easily deformed.

Aijiren not only produces autosampler vial, but also accessories for autosampler vial. Cap with Septa, especially the production of Cap, needs to be exactly the same as Autosampler Vial. It must also produce different types of Cap with different necks. Aijiren is a high-quality company. Chromatography consumable manufacturers, there is no error between the PP Cap produced, and it can perfectly match Autosampler Vials

It is worth noting that Aijiren’s production workshop is a dust-free workshop, but after packaging and transportation, Aijiren recommends that customers perform pre-cleaning treatment before using it. If customers need sterile Vial, they need to perform sterile treatment by themselves before using it.

Aijiren’s 9mm Screw Cap with Septa is automatically produced by machines. The same batch specifications meet the needs of customers for experiments. And mass production can also meet the orders of customers around the world, and mass orders can also be satisfied. Because of this, Aijiren’s fast shipping speed and good product quality have enabled Aijiren to become a world-renowned supplier of chromatography consumables.

The picture is one of Aijiren’s production plants. It can be seen that each of Aijiren’s workshops has a large space, which can accommodate a large number of production machines and the storage of raw materials and finished products. The right side of the picture is the adhesive-free composite of Silicone and PTFE. The Septa raw materials are placed on the shelves.

But for autosamplers with blunt autosampler needles, Aijiren still recommends buying septa with pre-slit, because this can prevent the septa from being pushed into the vial by the autosampler and contaminate the sample. Septa with pre-slit can complete the function of guiding the automatic injection needle.

Aijiren is a manufacturer of chromatography consumables specializing in the production of glass products. Its products include Autosampler Vials, Headspace Vials, Sample Storage Vials, EPA Vials, COD Test Tubes, etc. High-quality glass products ensure that customers can analyze more conveniently Experiment.

Aijiren uses PP Boxes for packaging. Generally, Aijiren uses 100pcs/pack, and the box has strong anti-impact ability. It is not easy to cause the vial to break during transportation. Aijiren’s 2ml hplc Vial has three different calibers to choose from. Screw, crimp and snap, the openings are divided into 8mm-11mm, many types are convenient for customers to choose.

Aijiren’s 2ml hplc vial is suitable for most autosamplers, because this 2ml hplc vial has a standard thread/snap/crimp caliber pattern and a uniform shoulder distance, which is very convenient for the robot arm of the autosampler to grab it. As shown in the picture, Aijiren will prepare PP Boxes for Vial in advance, and wait for Vial’s production or printing before packaging and shipping.

The 24mm Screw Cap produced by Aijiren is often paired with 24mm Sample Storage Vial. This type of Vial is used to store samples and sometimes used in autosamplers. For example, 40ml Vial is often called EPA Vial, and the center hole on the Cap is here. It will be useful in time, the sampling tool can easily pierce through the septa for sampling without causing sample contamination.

In addition to producing Autosampler Vial, Aijiren is also rich in matching Caps. Usually Caps are made of high-quality polypropylene for use in automatic sample injection vials. Aijiren uses a unified standard to produce PP Caps in an assembly line project to ensure that the Cap lines between batches are consistent and there is no difference. It is convenient for the customer’s laboratory sampling operation.

Aijiren’s 9mm Autosampler Vial, Screw Threads neck fits perfectly with Closures, and the thread seal is also convenient for customers to operate. This type of vial is a hot selling model that can be applied to all models of Autosampler.

The 9mm Screw Closures produced by Aijiren have many advantages such as high quality, strong adaptability, resistance to cracking, high temperature resistance, chemical resistance, etc. Since 9mm Screw Closures have many different styles and materials, the demand for 9mm Screw Closures is very high. High and diversified options also allow customers multiple choices.

20mm PTFE Septa can overcome the degradation that occurs due to long-term high temperature, because it is very common in silicone rubber septa. Degradation causes baseline drift and extra peaks. Therefore, the 20mm PTFE Septa produced by Aijiren is usually fixed with the PTFE side facing the column packing. For most GC/MS and other high-sensitivity detectors, Aijiren recommends septa materials with the PTFE logo; these are the cleanest and highest performing products. The PTFE septum contains very low levels of contaminants, which minimizes interference with the analysis and guarantees excellent results on all major LC/MS and GC/MS instruments.

Septa-silica gel has strong repetitive sealability, and it can maintain good close performance after multiple injections; PTFE is a material with better chemical conditions at present, and it can withstand strong acids and alkalis. The two materials After compounding, the bottle can be used for various laboratory purposes such as sealed sampling, chemical storage and so on.

The PTFE layer of Aijiren’s 20mm PTFE Septa composite diaphragm is in contact with the reagent. It is chemically inert, resistant to acids, alkalis, temperature and adhesion. Even at high temperatures, it cannot work with concentrated acids, alkalis or strong oxidants. At the same time, the elasticity of the silicone rubber or silicone layer can ensure the sealing performance; Aijiren abides by strict production management to ensure the quality of the product. The product is clean and can be used directly without washing.

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.

The packaging of Sample Storage Vial produced by Aijiren uses PP Box, 100pcs is a box, Aijiren’s minimum order quantity is generally 10 boxes, because the order of too small quantity will cause the volume of the vial to be larger, and the shipping cost is more expensive than the product price. In order to avoid this situation, Aijiren set the sample storage Vial’s minimum order quantity to 10 boxes.

The Headspace Vials produced by Aijiren have two different calibers, one is Crimp Neck and the other is Screw Neck. Aijiren uses borosilicate hydrochloric acid glass to make Headspace Vials, because the borosilicate hydrochloric acid glass can ensure the stability of the reagent when it is inside the Vias. And it can also ensure the safety of Vials itself. The borosilicate glass used by Aijiren is resistant to high temperature, not easy to break, not easy to burst, and easy to use.
