Eppendorf Safe-Lock Tubes combine all the experience of over 45 years of constant improvement and development. The original Eppendorf Safe-Lock Tube gives your sample outstanding stability during centrifugation, perfect sealing and evaporation protection. Trust in the original Eppendorf Safe-Lock Tube because your samples deserve the best treatment!

Always recognize the Eppendorf Safe-Lock tube by the "ep" in the lid. The hinged lid on Eppendorf® Safe-Lock tubes provides outstanding protection against accidental opening of tube lids ensuring absolute sample protection. This feature is especially important when working with precious samples or hazardous materials (e.g., radioactive probes, virus samples), or buffers containing detergents such as SDS.

• Hinged Safe-Lock lid prevents accidental lid opening and allows contamination-free lid opening
• Polypropylene provides high resistance to chemicals, mechanical stress and temperature extremes
• 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
