Edmund Buhler RM 2 Tube Roller Laboratory Shaker

A gentle rolling and tilting motion

The Edmund Buhler RM 2 combines a rotating and tilting motion (3 degree fixed tilt) to resuspend samples without generating foam.

This mode of agitation particularly suits blood tubes, cell cultures, and shear-sensitive samples.

Removable rollers and vessel compatibility

The unit is fitted with 6 removable plastic rollers, each 300 mm long and 32 mm in diameter. They accept any standard tube, flask, or vessel up to 80 mm in diameter.

The removable spill tray under the rollers makes cleaning easy in case of spillage.

Speed and runtime

Speed runs from 5 to 80 rpm in steps of 5, with a 15 mm stroke at the roller end and a fixed 3 degree tilt angle.

Maximum load of 2 kg on the 200 x 300 mm surface
Runtime from 0 to 99 hours 59 minutes, or continuous
Ambient operating temperature from 5°C to 45°C

Small footprint and vertical accessory

With a footprint of 244 x 465 x 115 mm and a weight of 7.3 kg, the RM 2 takes up little bench space.

An optional overhead rack (0060 003), with 12 holes of 29.5 mm diameter, turns the unit into a vertical rotation (overhead) mixing system.
