AUTOMATIC VACUUM MIXER Compact in size, powerful and reliable, Dentalfarm vacuum mixers are ideally suited to blend in plaster, investment materials, alginate and silicon compounds (in this case the optional 200cc mixing bowl is ideally suited). Operation can be manual or automatic controlled over an electronic built-in timer with an alarm at the end of cycle. The MIX-R PROGRAM offers the feasibility for fully customized cycles with adjustable rotation speed, slow start-up and reverse rotation.
