WARNING: For the safety of both the operator and service personnel,
care should be taken when handling substances that are known to be toxic,
radioactive or contaminated with pathogenic microorganisms when using
this centrifuge. When Risk Group II materials are used (as identied in the
World Health Organization “Laboratory Bio-Safety Manual”), a Bio-Seal should
be employed. The rotor and rotor accessories should not be considered as
Bio-Seals. More than one level of protection must be provided in the case of
materials of a higher group. The use of ammable or explosive materials as
well as those materials which chemically react vigorously is prohibited.
Model Description
The Horizon Model 842VES is a continuous-duty, digitally-controlled centrifuge
designed for the separation of uid samples. The 842VES oers 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 reduce processing times. The exclusive Drucker horizontal
rotor allows for quick and easy sample loading and complete horizontal separation.
Save settings in one of 10 memory locations and recall them at the touch of a
button.
Intended Use
General purpose laboratory centrifuge for sample
seperation.

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 16” is required in order to open the lid.
b) The clearance envelope is the space around the centrifuge which is required for
safety. Choose a setup location which will allow for a clearance envelope of at least
24” x 24”, (with the centrifuge at the center). No person or hazardous material shall
be permitted in the clearance envelope during operation. The operator time within
the envelope shall be limited to the time necessary for loading, unloading and
centrifuge operation only.
c) Proper ventilation is necessary to prevent the overheating of samples as well as
premature failure of the centrifuge. Choose an area which will allow unencumbered
air ow.
d) The centrifuge is designed to rest on its four rubber feet. No adjustment is necessary
for leveling the centrifuge, however, the surface should be at and level.
e) Be sure the outlet is always within reach as the line cord is the means of
emergency disconnection!
Initial Setup Procedure:
If any problems are found during the initial setup procedure, refer to the troubleshooting
section. For further assistance, contact The Drucker Company at 814-342-6205 or 814-342-6205.
1. Plug the female end of the line cord into the rear of the centrifuge. Plug the male end into
an approved electrical outlet. For electrical safety, the unit must always be properly
grounded.
2. For operator safety, the locking system is always active; requiring power and direction
from the user to disengage it (the lid also automatically unlocks at the end of a run when
it is safe to do so). To unlock the lid (in order to access the rotor chamber) press the
‘OPEN / STOP’ button on the control panel. The ‘UNLOCKED’ indicator light should
illuminate. If it does not, refer to the section on troubleshooting. The lid will remain
unlocked for 15 seconds after pressing the ‘OPEN / STOP’ button.
3. Turn the latch counterclockwise and open the lid.
4. Spin the rotor by hand; check for free and level rotation. If the rotor does not spin freely,
refer to the section on troubleshooting.
5. Place the test tube holders inside the rotor and verify that they are seated properly.
6. Close the lid. Rotate the lid knob clockwise to its complete stop position. The
’LATCHED’ indicator light should be illuminated. If it is not, make sure that the lid is
latched properly. The centrifuge will not run unless the lid is latched properly and the
’LATCH’ indicator light is illuminated.
7. Use the up arrow button next to the RPM display to set the speed to 4000 RPM.
8. Initiate a test run by pressing the ‘START’ button.
9. The ‘RUNNING’ indicator light will illuminate.
10. The test tube carriers will slide up into the horizontal position (horizontal rotor only) and
the unit will accelerate to the current set speed.
11. 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’ button
immediately and refer to the section on troubleshooting.
12. Press the ‘OPEN / STOP’ button to terminate the test run. The rotor will decelerate to a
complete stop and the lid will then unlock automatically for sixty (60) seconds.
13. Take time now to familiarize yourself with the various additional user settings. Turn to
page 11.
14. The centrifuge is now ready for operation.
