The easy-to-open, securely closing, Flex-Tube® offers comfort and dependability for sample preparation, centrifugation, and storage. One vessel for all applications in molecular biology, chemistry, and biochemistry.
Safer than ever: Flex-Tube® is designed for centrifugation up to 30.000 x g!
Eppendorf consumables incl. the Flex-Tube® are made exclusively from high quality, ultra pure polypropylene, which complies with FDA guidelines 21 CFR § 177.1520 »Olefin Polymers«, and 21 CFR § 178.2010 »Antioxidants and Stabilizers for Polymers«. Extensive quality checks are in place prior to and during production. Furthermore, the final product is examined for functionality. The functionality tests for tubes include lid closure security in a boiling water bath, centrifugation stability and vapor tightness. These quality controls and tests ensure the sustained high product quality across the entire production phase – lot by lot. Please see APPLICATION NOTE No. 056 for details: The best material for original Eppendorf Tubes® and Plates: Properties and chemical resistance of polypropylene
Highest sample integrity!
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 or measurements, e.g. nucleic acid quantification by photometric measurements at 260 nm.
