Analytical Vials. Vials play a significant role in analytical analysis and result reproducibility. Vials must be inert and free of extractables or leachables to prevent affecting results. Using certified, application-specific, contaminant-free vials can significantly reduce risk. We offer a broad spectrum of Supelco ® products including

The HPLC test detects trace levels of chemicals used in the manufacturing and packaging process.
All Waters clear glass vials are Type 1, 33-expansion glass. Type 1, 51-Expansion Glass More alkaline than 33-expansion glass and is adequate for many laboratory uses. It has an expansion coefficient of 51x10–7 ˚C and is composed primarily of silicon and oxygen, with trace amounts of boron. All Waters amber glassware is Type 1, 51-expansion
Depth filters made from glass fibers with a 0.7-um pore size are used to filter samples for analysis of organic compounds because they can be precleaned with organic solvents or baked at 450 C. Depth filters have a high-loading capacity, making them more suitable for filtering the larger sample volumes (1 to 3 L) are needed for organic analysis.

samples for waste-indicator compound analysis were collected in either 250mL or 1L amber glass bottles. Water samples for pesti-cide and PPCP analysis were collected in sterile 40mL amber glass Volatile Organic Analysis (VOA) vials. Samples were immediately transported on ice to the laboratory and stored at 4 C until further analysis.
6.1 SAMPLE CONTAINERS - Clean, amber volatile organic analysis (VGA) vials fitted with PTFE-faced silicone septa and polypropylene screw caps (I-Chem Cat. No. S146-0040 or equivalent). Prior to reuse, wash vials and septa (if not punctured) with detergent and rinse with tap and distilled water.

For many years, stream samples for analysis of volatile organic compounds have been collected without specific guidelines or a sampler designed to avoid analyte loss. In 1996, the U.S. Geological Survey's National Water-Quality Assessment Program began aggressively monitoring urban stream-water for volatile organic compounds.
Thermo Scientific™ Premium Pack Amber Glass Vials with Closed-Top Cap are Certified to meet EPA Performance Based Specifications for Volatile Organic Analysis, and are recommended for light sensitic analytes—available in 20mL or 40mL sizes.
