Centrifuge Tube, Conical Bottom, PP/HDPE, 50mL, Sterile, Amber, Pack of 500

Details:

These polypropylene tubes come with blue HDPE leak-proof screw caps. The tubes and caps feature specially designed flat threads for vacuum-type closure, which provides a leak-free seal at pressures exceeding 700mm Hg. The highly smooth, hydrophobic internal surfaces minimize the wall effect. Additionally, silk-screened graduations and a frosted surface make writing easier.
