The Stuart SSM4 Rocker by Cole Parmer has a bright LED display. The adjustable digital timer automatically stops after the set time (1 to 9999 minutes, 1 second to 90 minutes or 1 minute to 9 hours).  Select the speed between 5 to 70 rpm; both are set using the encoder control knob, allowing repeatability of mixing.

Movement is a see-saw rocking action, generating a wave motion through samples, ideal for the gentle mixing of live culture flasks and Petri dishes. Suitable for use in incubators or environmental chambers up to 40°C, maximum humidity 80%.

A non-slip mat and platform lip secure vessels. The SSM4 is the mini model and has a platform size 235 x 235mm, ideal for small laboratories where bench space is limited or for personal use. Triple the capacity by adding the optional accessory tier system, which uses a magnet assembly to provide two stacking platforms. Fitting does not require tools, and the tier system can be dismantled for cleaning.
