20mm Crimp-top Aluminum Rubber Septa typically refers to a type of closure system used in laboratory settings. It consists of an aluminum cap combined with a rubber septa.
The aluminum cap is designed to seal the opening of a container, such as a vial or bottle, and is typically made of aluminum or aluminum alloy.
It provides a secure closure to prevent leakage, contamination, or evaporation of the contents.
The aluminum cap ensures a secure fit, while the rubber septa provide a barrier against leaks, contamination, and sample evaporation.

Aijiren Crimp Top vials are excellently fitted for autosamplers and have good chemical compatibility and super cleanliness. The crimp top sample vial is the most commonly used gas sampling vial on the market at present. 2ml volume sample vial especially suitable for laboratory use.

The Cap of Closures in the picture has a Center Hole, which is convenient for Autosampler to perform needle sampling. If you are worried about the difficulty of automatic injection needle sampling, you can also consider purchasing a pre-slit septa. This type of septa is divided into a cut and a cross The two types of incisions are especially useful for blunt circular injection needles.

COD testing is a good better indicator of organic pollutants in industrial wastewater containing cyanides and heavy metals. COD testing affords rapid response to changing conditions before critical problems develop.

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.

As a production company, Aijiren has its own independent production plant and independent laboratory. This laboratory exists to test the quality of Aijiren’s products, especially 2ml HPLC Vials. As Aijiren’s popular product, Aijiren is right Its quality control has always been very strict, requiring laboratories to conduct actual experiments for testing.

11mm Snap Top Closures are made of PP. The translucent Cap design allows users to see the fixed card slot. The inside of the Snap Cap has 4 protrusions for fixing in the lateral groove of the Vial Neck.

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.

Equipped with Silicone/PTFE Septa, and can also be used with slit septa. Usually the available cap color is silver, but other special colors can also be produced accordingly. There is a 9.5mm center hole in the center of the cap for automatic sample injection.

Aijiren Vials have a standard 11.6x32mm profile and are compatible with convenient 11mm snap cap or aluminum seal closures.
Aijiren Vials have a 40% larger opening than screrw vials for easier sample filling and to reduce the chance of bent or broken needles during sampling.

The production process of high-performance total organic carbon (TOC) sample bottles is kept clean, and the workshop and production process are guaranteed to be clean, which can reduce instrument background and ensure top-level system performance for low-level monitoring.
It is equipped with a polypropylene cap with an open top and a PTFE/silicone low-leakage gasket bonded to the cap. The level 1 vials have been assembled and quality checked before leaving the factory.

Aijiren 2ml sample vial is made of transparent Class 1 Class A or Amber, Class 1 Class B, borosilicate glass. The Aijiren vial has a standard graduated patch for easy filling and identification
The PP Snap cap used with the Aijiren Vial system is a convenient alternative to the aluminum seal. The snap cap does not have a good sealing performance without the aluminum seal. It is recommended only for short-term sample placement.
