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

From Eppendorf, these amber micro test tubes in a 0.5 ml format are designed for the secure handling of small-volume samples in research and diagnostic laboratories. The signature hinged Safe-Lock lid is engineered to prevent unintentional opening during incubation and storage while remaining easy to open when needed.

Manufactured from polypropylene without the use of slip agents, plasticizers or biocides, the tubes offer high chemical and mechanical resistance. They provide precise sealing for minimal evaporation during long-term storage and demonstrate centrifugation stability of up to 30,000 × g, helping to prevent sample loss through tube breakage. The polypropylene is finished with a frosted lid and side surface to support easy labeling.

Functionality is guaranteed from -86 °C to 100 °C, and the tubes can be autoclaved when open at 121 °C for 20 minutes. They are batch certified in Eppendorf's PCR Clean or Biopur purity grades for sensitive molecular biology applications.
