WARNING: Care should be taken when handling substances that are known to be toxic, radioactive or contaminated with pathogenic microorganisms when using this centrifuge for the safety of both the operator and service personnel. When Risk Group II materials are used (as identiﬁed in the World Health Organization “Laboratory Bio-Safety Manual”), a Bio-Seal should be employed. More than one level of protection must be provided in the case of materials of a higher group. The use of ﬂammable or explosive materials as well as those materials which chemically react vigorously is prohibited.

Model Description:

The Horizon Model 755 is a continuous-duty, electronically-controlled, single or variable-speed, horizontal

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. The imbalance detection system safely terminates a run cycle in the event that a severely imbalanced load is present. 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.

Intended Use:

General purpose laboratory centrifuge for sample preparation.

Begins a new run, (the lid must be closed, see pg. 6).

Allows access into the rotor chamber by disengaging the locking mechanism. Entry is only permitted when the rotor is stopped. Pressing this button during operation will terminate the run and unlock the lid after the

rotor has come to a stop.

This counter increments once for each run of the centrifuge. This count is used for both warranty purposes and for routine maintenance.

The lid safety switch prevents the centrifuge from operating while the lid is open. If the knob is not turned completely clockwise to its stop position the centrifuge cannot operate. Programming functions are accessed by ﬁrst opening the lid safety switch.
