Eppendorf Safe-Lock Tubes are the result of 50 years of continuous improvement and development. The original Safe-Lock tubes protect your sample with excellent centrifugation stability, feature optimized sealing properties, and reliably prevent sample evaporation. Trust in the original Eppendorf Safe-Lock Tubes, because your samples deserve nothing but the best.
Safer than ever!
Tests at 30,000 × g have shown that vessels can break during centrifugation. Eppendorf Safe-Lock Tubes are guaranteed to withstand very high centrifugation forces. Depending on the Safe-Lock Tube variant (see table), forces up to 30,000 × g are possible – allowing you to safely centrifuge without sample loss.
