22 Multi Mix Rotator


The MTR22 Multi-Mix has the capability to perform three 

modes of mixing, all of which are programmable and can

all be used in the same "run". Or, if you just want to

rotationally mix, set the unit to rotate.

It is very simple to operate and program, runs

can be programmed in seconds. You can mix many
different sizes of tubes ranging from 1.5 ml to 50 ml with the
two interchangeable mixing platforms that come standard with
the unit. Tubes are held in-place with unique rubber flexible
grippers; that surround and firmly hold tubes of varying


The MTR22 can mix in the following motions:
1. Rotate 360°, forward or reverse, and forward, then reverse
2. Reciprocating Rocker, back and forth like a traditional rocker
3. Vortex, (cavitate)


• RPM: Variable from 5 – 30 RPM
• Timer: Up to 999 Seconds, max mixing time: 12 hours
• Reciprocating Timer: Up to 999 Seconds
• Rotation Angle in Reciprocation Mode: 15° - 90° (in 15° increments)
• Turning angle vortex mode: 1 to 5
• Vortexing times: 1 to 5
• Maximum timer: 12 hours
• Power: 110 / 220 V




Barnstead/Thermolyne Multi-Tube Rotator


Ideal for use in hematology, blood-chemistry, and other applications where a continuous, gentle rocking motion is necessary.

Features bi-directional rotation. Provides a circular motion and a rocking pattern to keep liquids and solutions mixed without the potential for shearing or other damage. Rotator's four rubber feet provide stability. Double-sided, non-skid platform surface is made of white silicone and can hold 7mL, 10mL, or 15mL tubes firmly in place. Lightweight metal body is compact and is easy to transport. Angle of rotation is 20° from the horizontal plane.
