The snap vials are less prone to breakage during decapping because more glass is used in the neck of the vial. The snap seal neck finish is compatible with either crimp or snap seals and no special tools are required to remove the cap. These vials are recommended for short-term sample storage and non-volatile samples because the seal is not as secure as a crimp or screw thread seal.

Screw Cap Vials are universal. Screwing the cap applies a mechanical force that squeezes the septum between the glass rim and the cap. Screw caps form an excellent seal and mechanically hold the septum in place during piercing. No tools are required for assembly.

The snap-on vials produced by Aijiren are made of Type 1 borosilicate glass (Grade A, 33 expanded borosilicate glass), with transparent or amber color, or made of polypropylene. The snap vial can accept either aluminum snap seal or polyethylene snap cap. Very suitable for short-term storage.

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.

Polypropylene Screw Cap with Septa – Polypropylene screw cap with precision-fit septa provide an evaporation-proof seal. Bi-layer include silicone and PTFE. Silicone septa for multiple injections. PTFE-lined screw cap for organic samples. Screw caps provide an inert, airtight seal and direct puncture-access to samples with a syringe needle.

Caps with solid PE liners offer good chemical resistance and low moisture vapor transmission rate and is great for nail polish remover and higher concentration acids & alkalis. Good for non-oil products filled at room temperature. Because this lining system is paperless, your samples will not be contaminated with fiber or paper particles from the closure. Available in Phenolic caps.

Aijiren’s HPLC Vial is divided into two types: clear glass and amber glass. The clarity of clear glass is more obvious. The reagent changes in the vial can be clearly seen. The amber glass can protect the sample in the vial from deterioration due to ultraviolet radiation.

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.

We provide septa and caps to fit our autosampler crimping the top vial to provide PTFE protection and silicone resealability. The cap includes a double-sided PTFE septum with silicone in the middle.

2ml Snap Top HPLC Vial is made of Type 1 borosilicate glass. Comparing with 9mm screw vial, this 2ml Snap Top HPLC Vial mouth is wider opening. So 2ml Snap Top HPLC Vial is easier to fill and provides a larger target area for the autosampler needle. That means, the 2ml Snap Top HPLC Vial can protect the needle.

Let me introduce the material of 8-425 2ml autosampler vials, 33 Expansion borosilicate glass USP Type I Class A made of clear vial, or 51 Expansion borosilicate glass USP Type I, Class B made of Amber vial.Our glass uses neutral borosilicate and low borosilicate, but our neutral borosilicate can reach the standard of high borosilicate, and our low borosilicate can reach the standard of neutral borosilicate. We use excellent raw materials to make 8-425 2ml autosampler vials.

Features of the Crimp Top Sample Vial
Rigorous quality assurance ensures consistency of dimensions between lots
Optional ceramic writing spot with fill mark
Full warranty compatibility certification with autosampler

All of Aijiren 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. At the same time, some vial bottoms are designed with round bottoms, so that it has a flat bottoming function and compatibility with automatic sampling equipment.

Micro Insert is used to ensure the most accurate and reliable analysis of your lab samples. Autosampler vial inserts are available with polyspring conical, pulled point conical, or flat bottom insert formats

These vials are made of high-quality materials, such as borosilicate glass, providing excellent chemical resistance and sample stability. The clear glass construction allows for easy visibility and inspection of the sample, while the 8-425 thread ensures convenient sealing and unsealing of the vial during sample preparation and analysis.

The 150ul, 250ul, and 300ul Micro Inserts for HPLC Autosampler Vials are essential accessories designed to enhance the functionality of HPLC sample vials. These micro inserts are made of high-quality materials, such as borosilicate glass, providing excellent chemical resistance and minimizing sample contamination.

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.

1 mm shell vials typically refer to small, cylindrical vials with a thin outer shell. They are commonly used for chromatography applications, such as gas or liquid chromatography. Micro-vials generally refer to very small vials with a reduced volume capacity. They are often used for storing small quantities of samples or for high-throughput analysis in laboratories.Integrated screw snap crimp vials combine the features of screw vials and crimp vials. They typically have a threaded neck that allows for easy screwing of a closure, such as a screw cap, and also feature a snap-top design that allows for secure crimping.
