Digital Roller Mixer - Forward/Reverse Tube Roller - 20-99 rpm - 6 Rollers, 25 mm Amplitude

The Master Science Digital Roller Mixer is designed for mild mixing and for keeping biological samples in suspension. Typical uses include preventing blood coagulation, latex agglutination diagnostics and immunoprecipitation.

Six 280 mm rollers rotate at 20 to 99 rpm with a combined rolling and swinging motion of 25 mm amplitude, carrying up to 4 kg. Digital displays show speed and time, and the Master Science Digital Roller Mixer can automatically switch between forward and reverse rotation at intervals from 30 seconds to 99 minutes 59 seconds for even more uniform mixing.

Problems the Master Science Digital Roller Mixer Solves

Samples that settle or clot can ruin results. The Master Science Digital Roller Mixer helps with:

• Sedimentation in tubes: Continuous rolling keeps particles suspended.
• Uneven mixing in one direction: Automatic forward/reverse rotation mixes more uniformly.
• Unattended long runs: The timer runs up to 99 hours or continuously.
• Over-vigorous mixing: Low speeds from 20 rpm protect delicate samples.
