NALGENE® 3148 Conical Oak Ridge Centrifuge Tube, polypropylene copolymer; polypropylene screw closure

These conical centrifuge tubes combine the better separation/pelleting capabilities of a conical tube with the superior sealing capabilities of Oak Ridge tubes. Graduations silkscreened from 5 to 35mL in 1mL increments. Accommodate NALGENE® sealing caps (NALGENE 3132-0024) and require conical tube adapter (NALGENE 3147-0050). Molded of PPCO for better chemical resistance. Tubes are translucent but contact clear for easy liquid viewing. Before autoclaving, just set closure on top of tubes without engaging the threads. Autoclavable/Leakproof.
