RAM Resonance Acoustic Mixer

The RAM® bench top biological mixer utilizes ResonantAcoustic® technology that applies low-frequency, high-intensity acoustic energy to agitate microbial cultures. The RAM® is a highly-efficient orbital-shaker replacement that dramatically enhances oxygenation and bulk mixing for bacterial and fungi cultures. Combined with the patented Oxy-Pump® stopper, oxygen transfer rates up to 6-fold higher than orbital-shaken cultures can be achieved.

The RAM® is an indispensible product for any cutting-edge biological laboratory.
