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.

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.

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.

Aijiren can provide storage vials of various specifications, mainly used for water and soil analysis. This type of storage vial may also be called an EPA vial, specifically the 40ml screw cap EPA vial. The storage capacity of EPA screw-top bottles is 20ml-60ml, such as 20ml, 30ml, 40ml, and 60ml.

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.

2mL Amber Glass Screw Top Autosampler Vials are available in a variety of neck finishes and opening diameters. Large mouth or wide ID vials have approximately a 40% wider mouth opening than standard opening vials. The large opening reduces the risk of bent autosampler needles during sampling. When choosing a 2mL Amber Glass Screw Top Autosampler Vial, the product material is of paramount importance.
Screw-top vials also come in different sizes, with vial caps made of either aluminum for crimp seals or plastic. Amber glass vials are available in 2-60 ml volumes with a screw top. Inserts work in conjunction with any autosampler and fit either standard or wide openings vials.

Polypropylene screw cap with septum-The polypropylene screw cap with septum provides an anti-evaporation seal. The double layer includes silicone and PTFE. The silicone septum can be injected multiple times. Screw caps lined with PTFE are used for organic samples. The screw cap provides an inert, air-tight seal and can be directly pierced through the sample with a syringe needle.

It can also be used in cosmetic liquids, essential oils, etc. All bottle caps have screw-in black polypropylene caps. Easy to carry, easy to place in the family. With screw cover, it is well sealed to avoid leakage. Used to store small amounts of chemical solutions and fumes

Our Screw Sample Storage Vial adheres to industry-standard specifications, ensuring compatibility with a wide range of laboratory equipment. The 15-425 thread size is commonly used, making it compatible with various autosamplers and sample handling systems.
