Lab Use Glass Test Tube with Screw Cap 13mm & 16mm

EPA vial also known as an Environmental Protection Agency vial, is a specialized type of sample container used for environmental analysis and testing. It is designed to meet the requirements and guidelines set by the U.S. Environmental Protection Agency (EPA) for the collection and storage of water samples.
EPA vials are typically made of glass or high-quality plastic materials such as polypropylene. They come in various sizes, commonly ranging from 20 milliliters (mL) to 40 mL, although larger sizes may also be available.
The vials are often equipped with a screw cap or a snap cap to securely seal the sample inside and prevent any leakage or contamination.These vials are specifically used for the collection of water samples to be analyzed for various parameters, such as the presence of organic and inorganic pollutants, contaminants, or other substances that may impact water quality.

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.

Our storage bottles (also called ladder bottles or dram bottles) provide a good solution for long-term storage of solvents. Our threaded vials provide enough threads per inch to eliminate evaporation with a strong top or lined cap.

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.

 EPA vials are 24mm screw top and suitable caps are sold separately. 24mm EPA caps are pre-assembled with a variety of septa, to suit a number of different applications.
