Centrifuge Tube, 15mL & 50mL, Graduated, Rainbow Screw Cap

SpectraTube™ is a new twist on a staple in the life science laboratory. We’ve taken the proven design of the 15 and 50mL conical tube and configured them conveniently in a foam rack with five different colored caps to make sample identification a breeze. These tubes are perfect for any lab conducting multiple studies, or any experiments requiring multiple sample types or solutions. All five cap varieties are flat, brightly colored, and frosted to make them easy to write on.

These conical 15mL and 50mL centrifuge tubes are made of premium polypropylene, with exceptionally uniform wall thickness for clarity and centrifugal strength. Tubes and caps may be used for sample storage at temperatures as low as -45°C. The maximum centrifugal forces are 12,000xg for the 15mL tubes and 15,000xg for 50mL version.* Tubes and caps are suitable for stem cell research and certified sterile, RNase, DNase, and Pyrogen free.
