Not all consumables are created equal!
Substances which are released from plastic consumables (leachables) may have an influence on laboratory experiments. When they absorb light in the UV range they can disrupt DNA and protein quantifications. The Eppendorf Tube 5.0 mL is manufactured without the use of slip agents, plasticizers and biocides –substances that have been shown to affect bio–assays and laboratory measurements– and thus offers a safe alternative for sample preparation and storage. Graph: Shown are UV absorbance spectra of pure water incubated (30 min. 90 °C) in tubes from different manufacturers. Data shown in the diagram were generated with 5.0 mL snap cap format – for additional information and protocol description please see Application Note 264.
