These 15 mL and 50 mL centrifuge tubes are suitable for centrifugation in various fields such as cell biology, immunology, microbiology and molecular biology, as well as for sample preparation and sample storage. Easy-to-read black graduations of 0.5 mL increments on 15 mL tubes and of 2.5 mL increments on 50 mL tubes have an accuracy of ±2%. A large, frosted surface allows for identification and labeling and is resistant to alcohol wiping.
