EPA vial, also known as an Environmental Protection Agency vial, is a type of sample vial specifically designed for environmental analysis, particularly in the context of water and soil testing. The EPA has established certain standards and regulations for environmental testing, and EPA vials are designed to meet these requirements.
EPA vials are typically made of inert materials, such as borosilicate glass, to minimize interactions between the sample and the vial. They are available in different sizes, typically ranging from 20 mL to 40 mL, to accommodate various sample volumes.

Our storage vials, also known as step vials or dram vials offer a great solution for storing solvents for extended periods of time. Our screw thread vials offer enough threads per inch to eliminate evaporaton with a solid top or lined cap.

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.

EPA vials are those that meet the requirements of the U.S. Environmental Protection Agency (EPA) for testing potentially harmful environmental contaminants in water or soil samples.

The screw cap vial is easy to handle. Tightening the lid with your hand and a mechanical arm will exert mechanical force, which will squeeze the septum between the glass vial and the lid. The screw cap forms an excellent seal and mechanically fixes the septum in place during the piercing process. No tools are required for assembly.

Aijiren is manufactured in the most advanced molding equipment using high-purity pure polypropylene.
PP is a material that complies with US FDA 21 CFR. Used to store PCR reagents, enzymes and other diagnostic reagents, as well as biochemical reagents or samples. The screw cap has leak-proof function and can be used at low temperatures.

Aijiren’s screw PP cover for sample storage vial is made of high-quality polypropylene. The color is usually black and white. You can choose whether to have a cap with a center hole. A cap with a center hole will make it easier for the syringe to be in the vial. Inject the sample or withdraw the sample.

Capacity ranges from 8mL to 12mL
Provide constant pH for duration of sample storage life
Chemically inert caps suitable for most chromatography and storage applications
Top grade PTFE/silicone septa used for cleanliness

15-425 Screw Sample Storage Vials made of high quality borosilicate glass for heating or autoclaving, instant syringe access to completely sealed reagents and standards. Aijiren Sample Storage Vials are available in two sizes for storage, heating and autoclaving.

Featuring rounded bottoms and a deep thread finish for an extra turn of security for those important jobs, these heavyweights are fully annealed for maximum strength.
The rounded bottom allows for the efficient transfer of heat and easier cleaning. 

Aijiren™ reusable media bottles are manufactured from high quality, borosilicate 3.3 glass. With their superior chemical resistance, these bottles are ideal for storage of reagents, culture media, biological fluids and a variety of other aqueous and non-aqueous solutions.

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.

Storage Vial is supplied by Aijiren. These vials are pre-sterilized and have a capacity of 60ml. 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.

Aijiren not only produces Vial for HPLC and GC, but also Sample Storage Vials for storing samples. Aijiren’s Sample Storage Vials are divided into amber and clear vials. Amber vial can protect the sample from ultraviolet rays.

The manufacturer’s lot number for each component of this product is tracked until all procedures are completed at which time a final lot number is assigned and documented. A randomly selected collection of vials from each completed lot are submitted to an independent validation laboratory for quality control purposes to confirm that the TOC vials comply with the quality specification. The vial, closure and dust cover undergo comply with stringent quality standards and specifications.

The storage vials are compatible with various laboratory storage methods, including refrigeration and freeze-drying. They can withstand a wide range of temperatures, allowing for long-term storage of samples under different conditions. The PTFE cap provides chemical resistance and ensures a tight seal, even during extreme temperature fluctuatio

EPA vials are those that meet the requirements of the US Environmental Protection Agency (EPA) for the testing of potentially harmful environmental contaminants in water or soil samples. To be used for environmental analysis, EPA vials must be clean and free of substances that might influence the analysis.

The Sample Storage Vial produced by Aijiren is suitable for environmental analysis and storage of samples. 15-425 has two different capacities, 8ml and 12ml, suitable for different types of samples.

Storage glass vials made of type 1, type A, 33 expanded borosilicate glass or 51A amber glass, with a capacity from 20mL to 60mL, provide a constant pH value to maintain the life of the sample, chemically inert caps are suitable for large For most chromatography and storage applications, top PTFE/silicone septa are used for cleaning.

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.
