Drucker’s Performance Series centrifuges. Its standard horizontal rotor and carriers can accommodate up to 24 test tubes. The 755VES offers control over almost every aspect of the unit’s operation from variable acceleration and deceleration to easy time and speed input. High speed and force capability produces platelet-poor/free plasma and greatly reduces processing times.

Setup Location 1. Unpack the centrifuge and verify that all of the supplied equipment is present. 2. Choose a setup location which meets the following criteria: a) A bench top clearance height of 20” is required in order to open the lid. b) The clearance envelope is the space around the centrifuge which is required for safety.
Initial Setup Procedure (continued) 10. The ‘RUNNING’ indicator light will illuminate. 11. The test tube carriers will slide up into the horizontal position (horizontal rotor only) and the unit will accelerate to the current set speed. 12. Listen to the sound of the centrifuge. A smooth whirring sound should be heard. If there are any loud or unusual sounds, stop the centrifuge by pressing the ’OPEN / STOP’...
Tube Holder Configurations The next two pages will describe proper balancing and tube loading. Use the appropriate section for the rotor installed in your centrifuge. Improper loading can result in damage to the centrifuge or test tube samples. Six (6) Carrier Horizontal Rotor (standard) This rotor is designed to hold up to 6 tube carriers.
Six (6) Place 50 mL Fixed-angle Rotor (optional) This rotor is designed to hold up to six (6) 50 mL tube holders. Your centrifuge must contain a balanced load in order to work properly. To ensure that the load is balanced, keep these rules in mind when inserting test tube samples into the 6 place, 50 mL fixed-angle rotor: 1.
Control Panel Functions Time Adjustment and Timer Operation: The run time may be set from 30 seconds to 99 minutes and 30 seconds. Press the up and down arrow buttons next to the time display to adjust the run time. Adjustments may be made prior to a run or after a run begins.
Advanced User Settings (continued) Braking Rate: The user may adjust the braking rate from minimum (slowest deceleration, 0) to maximum (quickest deceleration, 9) using the following procedure: 1. While the centrifuge is idle, press the PROGRAM button. 2. Use the UP/DOWN arrow buttons next to the speed display until “BRAKE” is displayed in the speed display.
Memory Locations / Storing and Recalling The Performance Series centrifuges are capable of storing up to 10 user-defined presets. These memory presets contain all of the settings needed to define a specific run, (run time, speed, acceleration rate, braking rate, etc.). The user can use these memory locations to quickly configure the centrifuge for a specific test type and ensure that the test is run in the same way each time by recalling this same setting.
Care and Preventative Maintenance With proper care and maintenance your Horizon centrifuge will provide years of laboratory service. For proper care, the following steps should be taken: 1. Provide Adequate Ventilation: For cooling purposes, the Horizon draws in ambient air through the air intake cover on the top of the lid and exhausts this air in the rear of the base.
Troubleshooting: 1. Problem: The rotor does not spin freely. Solutions: • Make sure that nothing has fallen into the rotor chamber. • If there is nothing obstructing the rotor, the motor may be damaged. Contact your authorized dealer or Drucker Diagnostics for further assistance. 2.
