Polypropylene tubes include blue HDPE leak-proof screw caps. The tubes and caps feature specially-designed flat threads for vacuum-type closure that is leak-free at a press of >700mm Hg. Highly smooth hydrophobic internal surfaces minimize wall effect. Silk-screen graduations and a frosted surface make writing easier.
- Autoclavable at 121°C and 15 psi for 30 minutes (tubes only, caps are NOT autoclavable)
- Radiation sterilized
- DNase, RNase, Pyrogen and latex-free
- Maximum RCF 14000
Amber colored tubes are suitable for light sensitive applications because they do not allow any light to pass through the samples.
