  • Page 3: General Description Of Operation

    Section 1 General Description of Operation This centrifuge is generally used in biological and biochemical research laboratories where small samples must be subjected to high RCF (g-force) for relatively short time intervals (usually thirty min- utes or less). Designed to accept popular micro-test tubes with captive caps in a high speed rotor, this centrifuge will provide centrifugal forces as high as 16,000 times the power of the earth's gravity (16,000 x g)* The major functional components of the centrifuge are as follows: Motor...

  • Page 7: Service Instructions

    Section 4 Service Instructions MAINTENANCE Beginning after the first 300 hours of use, and periodically thereafter, a qualified electronics technician should inspect the centrifuge. Cleaning & Lubrication The rotor, rotor chamber and centrifuge casing must be kept clean. Using a cloth damp with water or mild detergent, the casing and chamber should be wiped clean and kept in "like- new"...

  • Page 8: Rotor Screw

    Section 4 Rotor screw The rotor screw must be kept tight enough that it cannot be removed by hand. If it has become loose, tighten it firmly, clockwise, by hand and subsequently torque an additional 1/8 turn using a wrench or other appropriate tool. Speed calibration After every 100 hours of use (or more frequently if required by other agencies) the maximum rotor speed should be...

  • Page 9: Service Procedures

    Section 4 9) Adjust the low speed pot (front-most) so that the rotor speed measures 1,000rpm, plus or minus 100rpm on the tachometer. 10) Replace the metal chute The unit is now calibrated. SERVICE PROCEDURES Take care when performing the following service procedures. Always disconnect the unit from power source before attempting any service operations.

    Section 4 2) Unplug the motor connection from the PCB. 3) Loosen the ground nut and remove the motor ground lead (figure #4, pg 14). 4) Remove the 4 motor nuts on the bottom of the base- plate (figure #5, pg 15). Remove motor assembly and 4 star washers under the isolators from unit, noting the orientation and routing of motor and ground leads.

    Section 4 2) From the bottom of the unit, remove the 2 PCB mount- ing screws and nuts that secure the PCB brackets to the baseplate (see figure #6, pg 16). 3) One at a time, remove each of the 3 plug in connectors from the old PCB and install into the same location on the new PCB.
  • Page 12 Section 4 After removing, turn the upper casing so that the inside of the front panel is visible (figure #7, pg 17). If power to the solenoid is present, but the solenoid does not move, it should be checked and/or replaced. Other potential latch faults could be the result of poor wiring connections, poor alignment of the lid latch catch, sticking or jamming of the lid latch strike or no contact at the...
