Eppendorf tubes

This 1.5mL Eppendorf Safe-Lock  tube has a patented hinged lid that eliminates any danger of leaks, ensuring absolute safety when working with expensive or toxic samples, radioactive substances, or DNA. The hinged lid features a small hook that clips around the rim of the test tube to prevent the tube from opening accidentally (e.g. during temperature control processes), though it can be easily opened using just one hand. The tube can be used in a temperature range from -80 degrees C to +100 degrees C (tube lid is more likely to pop open at temperatures greater than 95 degrees C), and can be autoclaved when open at 121 degrees C for 20 minutes to sterilize. The tube also has volume graduations and frosted labeling surfaces.
