Centrifuge Tube, Conical Bottom, PP/HDPE, 15mL, Sterile, Pack of 500

Details:

Polypropylene tubes come with blue HDPE leak-proof screw caps. The tubes and caps feature specially designed flat threads for vacuum-type closure, which is leak-free at pressures greater than 700mm Hg. Their highly smooth hydrophobic internal surfaces minimize the wall effect. Silk-screened graduations and a frosted surface make writing easier.
