The easy-open, easy-close design of our Flex-Tube provides convenient and reliable sample preparation, centrifugation and storage.  The Eppendorf Flex-Tube is manufactured without the use of slip agents, plasticizers and biocides—substances that have been shown to leach from plastic consumables into the sample and negatively affect bio-assay results.

The Eppendorf Flex-Tube features precise lid sealing for minimal evaporation rates during long-term storage and g-Safe™: Exceptional centrifugation stability of up to 30,000 x g prevents tube breakage. This prevents sample loss and provides the extra safety when working with hazardous samples.
