10ml 20ml Crimp-top glass headspace GC vials for Gas chromatography

Disposable non-sterile syringe filter devices are designed to provide fast and efficient filtration, premium quality and economy. The membrane could be PTEF, PVDF, PES, Nylon, MES, PP, CA, and can be suitable for different situations.

Headspace vials are available in clear or amber glass with a round or flat base, a crimp seal with a beveled or square edge finish, or a screw-thread finish. Headspace vials, septum, and caps can be purchased in various quantities separately or together as convenience kits to fit your laboratory needs.

Aijiren screw thread top sample vials design is characterized by universal ease of use, especially the use of automated sample introduction systems, so this type of vial is also called a autosampler vial. And this sample vial is extremely compatible. The 1.5ml sample vial we usually say is the 2ml volume sample vial. The design of Aijiren screw thread top vials are developed from Europe and the United States, and the design feature is easy to use, especially the use of automated sample introduction system. Aijiren screw thread top vials also known as autosampler bottles.

If the weight, damage, surface inertness, and/or disposal costs of the glass vial are concerned, the vial manufactured from polypropylene is an alternative to consideration. The benefits of polypropylene materials include low extraction rates, compatibility with many solvents, ideal for working with proteins, ideal for ion chromatography applications, ideal for pH-sensitive sample storage, and eliminate the need for inserts during microsampling.

Aijiren’s Caps all come with Septa, and 9mm Cap is the most popular choice, because 9mm Cap with Vial are Aijiren’s hot-selling products. The screw Neck design ensures the consistency of the seal and the pattern, and the seal is good, and it is convenient for manual operation. The operation meets the needs of laboratory personnel, and the packaging of 100pcs meets the convenience of experimental use.

The micro insert is designed to ensure precise and accurate sample dispensing. Its tapered bottom allows for smooth and controlled sample aspiration and injection, minimizing the risk of sample loss and improving the reproducibility of your HPLC analysis. Achieve precise results with confidence using our Lab Use Micro Insert.

Storage Vial is supplied by Aijiren. These vials are pre-sterilized and have a capacity of 5ml. These vials can be used for storing biological material, human and animal cells. The cap is provided with a built-in seal ring which makes the vial leakproof. The base of the vial has longitudinal grooves which gives it a non-twisting character when placed in a vial rack.

COD digestion vials are specialized containers used in chemical analysis for determining the chemical oxygen demand (COD) of a water sample. COD is a measure of the amount of oxygen required to chemically oxidize the organic and inorganic compounds present in the water.
These vials are typically made of high-quality glass or borosilicate glass, which is resistant to chemical reactions and can withstand the high temperatures necessary for the COD digestion process. The vials are designed to hold a specific volume of the water sample and the reagents required for the COD test.

Aijiren manufacturer’s 11mm Snap top cap with Ptfe silicone septum is used for 2ml sample bottles. The neck of the vial has two horizontal lines, which is convenient for snapping the cap. The snap cap is very convenient to seal, but it is not suitable for storing samples. Only suitable for short-term storage of samples.

This COD test tube is designed with precision and functionality in mind. It features a rugged construction that can withstand the rigors of COD testing, including high temperatures and exposure to various chemicals.

The Aijiren reagent bottles are designed and manufactured in China.
Made of premium Borosilicate glass, these bottles offer maximum possible chemical resistance with minimal thermal expansion, making them the best choice for laboratory applications.
PP Cap and Pouring ring autoclavable to 140°C.

The Non-sterile Disposable Syringe Filter is a versatile filtration device used in laboratories for sample preparation and clarification. It consists of a polypropylene housing with a membrane filter, providing efficient filtration of particulate matter and microorganisms. These syringe filters are available in various pore sizes and diameters to suit different filtration needs, and they come in non-sterile packaging.

Open COD test tube, hold it at an angle and slowly add
2.0 mL of the pretreated sample solution from the reaction tube without mixing so that two separate layers
are formed.
Screw cap securely on to test tube, hold tube by the cap, place tube into the safety bottle and shake
(Caution, test tube becomes hot). Place tube into the heating block. Start heating programme.
After 2 h remove test tube from heating block, allow to cool down to room temperature and shake gently
several times.
Clean outside of test tube and measure.
Adjust photometer to zero by using blank value “NULL”

Crimp closures N11 are also universally suitable with regard to autosampler compatibility, however, they are not as safe and convenient in their closing technique as the screw closures N 9 (9mm) 2ml vials and closures.

0.3 ml clear glass micro insert fixed in 2ml glass vial. Conical base micro  insert vial can saving samples while during injection.  Wide opening top for better needle injection.

1.5ml 9mm Screw Neck Vial for automatic samplers is made of low metal type 33 and 51 COE borate glass to prevent sample instability or leaching. By selecting the cap and pad, we provide the best sealing solution for the sample.

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

Aijiren Storage vial is an ideal device for general laboratory use and storage of diverse samples due to excellent sealability and chemical tolerance. Besides, chemically inert caps are a good choice for most chromatography and storage applications. Top grade PTFE or Silicone septa are adopted to ensure cleaning production and consistent quality of sample vials.

Our 18 mm 10 mL screw-top bottles are made from premium borosilicate glass to withstand the rigors of GC and headspace analysis, ensuring the long-term integrity and stability of your precious samples

9mm thread caps, septums, 9mm 2ml HPlc screw vials are specifically designed for use with THERMO FISHER and other rotating or robotic arm samplers. 9mm2ml Hplc screw vials are manufactured in transparent glass, Type 1 Class A or Amber, Type 1 Class B borosilicate glass and contains a write patch for sample identification. Amber glass prevents exposure to UV light and protects sensitive samples.

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.

A disposable HPLC (High-Performance Liquid Chromatography) syringe filter is a specialized type of syringe filter designed specifically for HPLC applications. HPLC is a widely used analytical technique in chemistry and biochemistry for separating, identifying, and quantifying components in a liquid sample. These filters ensure that the sample is free from particles that could clog the column or interfere with the analysis

0.22 um 25 mm PVDF 0.22 um 25 mm (Polyvinylidene fluoride) syringe filter is a type of syringe filter that utilizes a hydrophilic membrane made from PVDF material. PVDF is a synthetic polymer known for its excellent chemical resistance, high thermal stability, and low protein binding properties, making it suitable for various filtration applications.The hydrophilic PVDF membrane used in these syringe filters has been modified to enhance its affinity for water and other aqueous solutions.

The crimp type vial, bottom diameter is 11.6mm, the height is 32mm, the neck diameter is 11mm. Actual capacity 2mL, standard capacity 1.5mL

Aijiren’s Headspace Caps often use metal material aluminum, which is soft and convenient for Hand Crimper and Decrimper for sealing. Not only that, the Septa produced by Aijiren is also made of high-quality silicone and ptfe, and is pressed with an exclusive process. This kind of septa is not easy to deform, break, and fall off, and it can also ensure the tightness of the vial.
