Screw Neck Cap Manufacturing

Aijiren has strict production requirements, meets ISO9001 certification, and the quality of the 2ml amber vial’s raw materials is high, which can protect light-sensitive samples from deterioration due to UV interference.

Aijiren adopts septa’s automated production, which guarantees Aijiren’s batch and efficient production. It is precisely because of this production that Aijiren has become a chromatographic consumable supplier in more than 200 regions around the world. If there is any need for chromatographic consumables, please Contact Aijiren.

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.

Purchasing Aijiren’s 9mm hplc sample bottle requires the purchase of 9mm Screw Cap with Septa. Aijiren’s Caps are made of high-quality polypropylene. You can choose whether to have a center hole cover. The septum uses a double-sided combination of PTFE and silicone. The assembled lid and septum are very convenient for customers to use.

PTFE/silicone septa are most commonly used in HPLC applications, and pre-cut septa are easier to pierce with a needle. The cap color is generally black, but other special colors can also be produced accordingly. Easy to apply and easy to remove. Pre-installed caps and septa are very convenient. Aijiren 13mm Screw Closures are commonly used in 4ml Screw Top HPLC Vial. Aijiren can recommend the most suitable Closures for your HPLC Vial.

The septum is made of the highest quality material to ensure the normal operation of the auto-injector.

Aijiren has its own production factory. There are many production machinery and tools in the factory. Aijiren’s assembly line machine production needs to rely on molds with consistent specifications. The screw cap is shaped by pressing high-quality polypropylene into the mold. Aijiren needs to be polished. Molds, customized high-quality molds can guarantee the high standards of product production.

The special packaging used in the 2ml vial in the picture, 100pcs in a box with a partition to separate the vial. This kind of packaging is not only more compact and beautiful, but also can better alleviate the vibrations that occur during transportation and protect the vial. At the same time, it can also bring the brand logo printed on the box, Aijiren can meet the customer’s packaging customization plan, only need to communicate the details in place and pay the corresponding packaging costs.

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.

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 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.

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.

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.

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.
