Nalgene* Polysulfone and Polypropylene Oak Ridge Centrifuge Tubes

Poly sulfone with polypropylene screw closure. Strong and tough like polycarbonate and much more acid- and base-resistant. Can be used up to 50,000 x g in refrigerated or non-refrigerated centrifuges. NALGENE sealing caps are available for all sizes. Before autoclaving, just set closure on top of the tube without engaging the threads. Must be filled to 80% of the total capacity.
