UNICO 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
diameters.
