Description
The VWR 89094-204 is a high-purity 40 ml sample vial specifically processed for Total Organic Carbon (TOC) analysis and other sensitive environmental testing. Part of the TraceClean specialty line, these vials are manufactured from Type I borosilicate glass and undergo a rigorous cleaning process in an ISO-certified facility. This ensures the vials are virtually free of organic contaminants, making them the industry standard for USP 643 testing, high-purity water sampling, and environmental volatile organic analysis (VOA).
Technical Performance and Design
-
TOC-Free Certification: Each lot is cleaned and certified to contain less than 10 ppb (parts per billion) of Total Organic Carbon, ensuring the integrity of low-level organic measurements.
-
Type I Borosilicate Glass: Constructed from chemically inert clear glass that minimizes pH shifts and prevents the leaching of inorganic ions into the sample.
-
Secure Septum Closure: Equipped with a 24-400 open-top polypropylene cap and a bonded PTFE/Silicone septum. The silicone provides a reliable reseal after puncture, while the PTFE face ensures chemical resistance.
-
Dust-Free Packaging: Vials are assembled and shrink-wrapped in a controlled environment to prevent secondary contamination during shipping and storage.
