The RSM7DC Rotary mixer is suitable for many applications where an end over end action is required, including blood and sample mixing. The tilting head allows for the disc to be held at any angle from horizontal to vertical enabling a wide range of different mixing actions. Loaded evenly with the locking screw removed the disc can rotate and be stopped by hand without switching off the drive, making tube placement and removal a simple operation. A centre locking screw is provided for heavier and unbalanced loads. The RSM7DC is supplied with a disc that has 20 threaded inserts and clips for tube diameters to suit customer specifications. Individual clips can be removed and replaced if required.
