Safe-Lock micro test tubes, 0.5 ml, colourless, 500 pcs.

Eppendorf Safe-Lock micro test tubes are designed for reliable sample protection in laboratory workflows. The hinged Safe-Lock lid prevents unintentional lid opening during incubation and storage, the result of 50 years of continuous improvement and development. A g-Safe® rating provides exceptional centrifugation stability up to 30,000 × g, helping prevent sample loss due to tube breakage and offering extra safety when working with hazardous samples.

The tubes are made from polypropylene, delivering high resistance to chemicals, mechanical stress and temperature extremes, and are manufactured without the use of slip agents, plasticizers and biocides — substances that have been shown to leach from plastic consumables into samples and negatively affect bio-assay results. Precise lid sealing supports minimal evaporation rates during long-term storage, and a large frosted lid and side surface allow easy labeling.

Functionality is ensured from -86 °C to 100 °C, and the tubes are autoclavable when open at 121 °C for 20 min. The 0.5 ml colourless tubes are also available in lot-certified PCR clean, Eppendorf Forensic DNA Grade and Biopur® quality grades for tested purity, as well as in Eppendorf Protein and DNA LoBind material for maximum recovery of valuable samples, and in Amber for light-sensitive samples.
