COD (Chemical Oxygen Demand) digestion vial is a specialized laboratory glassware used for the determination of chemical oxygen demand in water samples. COD is a measure of the amount of oxygen required to chemically oxidize organic and inorganic substances present in water.
COD digestion vial typically consists of a glass or plastic vial with a tight-fitting screw cap. The vial is designed to withstand high temperatures and chemical reactions that occur during the COD digestion process.

Headspace vials can withstand the higher temperatures and internal pressures required for volatile gas analysis. With very low metal content, extractables and leachables, they meet high standards to meet your regulatory requirements. These headspace vials are specification-certified for physical dimensions and autosampler compatibility.

The 18mm Screw Headspace with caps with electromagnetic screw seals used for CTC is novel in the headspace vial market dominated by crimping necks. Especially for magnetic caps that are difficult to crimp, screw caps are a convenient choice. 18mm Screw Headspace with caps with aluminum skirt and magnetic center plate, it is easy to crimp and remove the cap. 18mm headspace vial with cap is preferred for the following instruments: Shimadzu.
How to choose whether to buy the Headspace Vial with round bottom or flat bottom? The round bottom is stronger, so it is more resistant to the high pressure in the sample Vial during heating. In addition, the vial is easier to slide into the heating block when transported by the magnet. When the vial must run in the instrument with a slight downward trend, a flat bottom may be required.Select the correct Headspace Vial at the bottom and use modern instruments to prepare the entire experiment with highly repeatable samples for accurate analysis.

Some reagent bottles are tinted amber (actinic), brown or red to protect light-sensitive chemical compounds from visible light, ultraviolet and infrared radiation which may alter them; The bottles are called “graduated” when they have marks on the sides indicating the approximate (often with a 10% error) amount of liquid at a given level within the container. A reagent bottle is a type of laboratory glassware.?

The sterile syringe filter provided by Aijiren has a cellulose acetate or PES filter membrane. A sterile membrane with a pore size of 0.2um is an ideal material for sterilization and filtration, while a pore size of 0.45¦Ìm can be used for clarification. The sterile needle filter is sterilized by gamma radiation, which avoids the toxic residue caused by other sterilization methods

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.

High quality Aijiren 9mm glass vial for HPLC/GC analysis. Amber glass makes it compatible with sunscreen samples. 0.3 ml clear glass micro insert can be fixed in a 2ml 9-425 amber glass vial. The size of the insert bottle is 6 * 29mm. The vial is compatible with all types of 9-425 bottle caps, with a 9mm wide opening screw top, which can better perform syringe injection.

4ml borosilicate glass vials are commonly used in high-performance liquid chromatography (HPLC) for sample storage and analysis. Borosilicate glass is preferred in HPLC because it offers excellent chemical resistance and thermal stability, making it suitable for handling a wide range of solvents and temperature conditions.When working with water samples in HPLC, borosilicate glass vials are a suitable choice due to their resistance to water and other polar solvents.

HPLC Chromatography 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.  Screw Glass vial For autosampler instrument is made of borosilicate glass.

syringe filter is a small, disposable filter device that is commonly used in laboratory settings for the filtration of liquids. It is designed to be attached to a syringe, allowing the liquid to be passed through the filter membrane under pressure.

Features of the syringe filter: Luer lock inlet provides a sealed syringe connection, with various filter types, porosities and diameters. Color coding is easy to identify. Rugged polypropylene shell. Can be autoclaved to 121℃ for 15 minutes. The quantity exceeds the minimum order quantity to save more.

With the Aijiren COD tube test, each user can easily perform highly sensitive and accurate water detection.
The time required for the measurement process is significantly shortened, especially for standard analysis and series measurement, while significantly reducing the workload.
The COD Test tube contains a precise dose of reagent. Therefore, excessive chemical inventory is avoided and work safety is improved.

Torticollis headspace sample vial, 10mL or 20mL volume, flat-bottomed or round-bottomed 20mm crimp top vial cap to ensure consistent safety sealing.

Aijiren provides pre-assembled caps & septa, the dual-track cover pad assembly machine, used for the assembly of vial caps & septa, double tracks can greatly increase production efficiency; the pre-assembled vial closures can greatly reduce your experiment preparation work and improve experiment efficiency

The 2ml and 4ml Borosilicate Glass Autosampler Vials are meticulously designed for precise sample analysis in laboratories. Made from high-quality borosilicate glass, these vials offer exceptional chemical resistance and durability. They feature secure screw caps for a tight seal, ensuring sample integrity during storage and analysis. These vials are compatible with most autosamplers, providing seamless integration into laboratory workflows.

With PES syringe filter membrane mechanically strong character, it can handle high-temperature liquids, with great flow rate (better than PTFE), and low protein binding. With these features, PES syringe filters offer superior performance for use with biological samples and media culture. Workable pH range ~3-14.

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.

The 9mm screw cap produced by Aijiren has a center hole to facilitate the sampling of the injection needle of the autosampler. The injection needle will penetrate the septa and enter the interior of the vial for extraction. The thread pattern of the 9mm screw cap fits closely with the vial. Septa is slightly squeezed between the cap and vial to fill the gap, so the sealing is extremely high.
