Model 755E - 12 Place Centrifuge

The Horizon Model 755e is a continuous-duty, electronically-controlled, single speed, laboratory centrifuge with a lid safety interlock system. The unit is controlled by an electronic push-button timer that is variable from 1 to 30 minutes, for precise spin times and ease of use. Samples can be safely viewed through the transparent lid. Entry into the machine is restricted during operation by the safety interlock system. The Horizon features a lighted control panel that displays the status of the machine, easily viewable from a distance. Finally, a cycle counter keeps a count of the total number of machine runs for servicing and maintenance records.

Indicator lights:
‘RUN’ green -lights when power is applied to the motor
‘LATCH’ yellow -lights when the lid is closed and latched
‘UNLOCKED’ red -lights when the lock system is deactivated
