Our centrifuge tubes are used to contain liquids during centrifugation, which separates the sample into its components by rapidly rotating it around a fixed axis. With conical bottoms, any solid or heavier parts of the sample being centrifuged can be collected. Our centrifuge tubes have large white writing areas and clear black graduations and are guaranteed free of human DNA, PCR inhibitors, RNase and DNase. They can be safely used up to 12500 rcf, with a temperature range from -80℃ to 120℃.
