Durable and reusable, these polycarbonate, conical-bottom centrifuge tubes were designed for use with the Raven Environmental Process Centrifuge. The shoulder of the tubes fit directly in the rotor trunnion rings of the centrifuge for easy insertion and removal. They are brightly marked with white graduated scale from 0.2% to 50% and 100% which allows very small amounts of solids compacted in the bottom of the tubes to be measured.Specifications:
