Testing of water supplies for potentially harmful chemicals such as pesticides, herbicides and polycyclic aromatic hydrocarbons requires controlled sample collection and processing
Chromacol produces a range of vials for environmental water analysis with Environmental Protection Agency (EPA) certification.
This is defined by cleanliness and sampling volume.
Chromacol EPA vials are available in two sizes of 20ml and 40ml capacities with a standard 28mm outer diameter.
They are available in clear or amber glass that meets ASTM Type I Class A and USP Type I standards.
To reduce possible contamination, the vials come pre-assembled with caps and septa manufactured from high purity polypropylene lined with silicone/PTFE injection septa.
Cleaning conforms to EPA standards with three levels of certification class - 100, 200 and 300; with Class 300 comprising batch certification for analysis of VOA components to less than 0.5ppm.
Furthermore, pre-applied bar coding of class 100 vials can be provided to customer specification.
