Culture tubes are designed for the Total Organic Carbon (TOC) testing and sampling.

• USP method 643 testing
• Off-line and grab sampling of high purity water
• Low background is perfect for preparation and storage of standards
• Cleaning validation is simplified and costs are reduced by using the TOC method of testing

All containers have open-top caps, unless otherwise specified, and fluoropolymer resin-lined septa.

Manufactured, tested and packaged by exacting standards, Thermo Scientific™ TOC Certified Containers are certified to contribute <10 ppb or <20 ppb TOC as background.

Vials feature a septum designed to stay inside the cap while sampling and are appropriate for use as autosampler vials or for sampling.
