Heidloph Reax control. With small holder plate test tube shaker - circularly vibrating. Exact speed display with indication of the speed. Improve your results with an electronic speed control - even in the low range and even with load changes, the speed remains constant. The strong 5 mm orbital agitator achieves uniform distribution reliably and quickly, even with solids and highly viscous media. Use the device in the short-term mode: In this mode, the shaking motion is triggered by pressure on the recording plate. You can switch to continuous operation - this mode guarantees a permanent shaking movement. Fastest mixing due to the high speed of 2,500 rpm. A mounting plate for tubes up to 20 mm in diameter is already included. An optional mounting plate for vessels up to 50 mm in diameter extends your scope of application. UPGRADE.
