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

These 0.5 ml blue micro test tubes from Eppendorf feature a hinged Safe-Lock lid designed to prevent unintentional opening during incubation and storage, with a precise seal that minimizes evaporation during long-term storage. The polypropylene construction provides high chemical and mechanical resistance, and the tubes are manufactured without slip agents, plasticizers, or biocides. A frosted lid and side surface allow easy labeling.

For laboratory use, the tubes offer centrifugation stability up to 30,000 × g, helping prevent sample loss due to tube breakage and providing extra safety when handling hazardous samples. They are guaranteed to function across a temperature range from -86 °C to 100 °C and can be autoclaved when open at 121 °C for 20 minutes.
