Eppendorf Safe-Lock Microcentrifuge Tubes-EPP 022363247

The patented hinged lid on Safe-Lock Microcentrifuge Tubes eliminates any danger of leaks. Safe-Lock Tubes ensure absolute safety when working with expensive or toxic samples, radioactive substances, or DNA. The 0.5 mL, 1.5 mL, and 2.0 mL test tubes have volume graduations and etched marking surfaces. A small hook on the patented* hinged lid clips around the rim of the test tube. Tubes can be autoclaved when open (121 °C, 20 min.). Can be opened easily using one hand l Etched marking surfaces. The lid hook prevents the tube from opening accidentally (e.g. during temperature control processes). Rated to 25,000 x g for excellent mechanical stability during centrifugation.
