Details:

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