Care and Maintenance
Specifications
MKT-7.5.3-L-156 | Rev 5
With proper care and maintenance, the E8 centrifuge will provide years of laboratory service. Please follow the
following recommended guidelines:
Use only quality test tubes which are rated for 1534 g-force or greater.
Never force a tube into the tube shield. The tube shields were designed to hold the most common sized tubes, Vac-
cutainers, and SST’s. Some plastic, conical, and glass test tubes are too large and should not be used in the E8.
Keep the tube shields clean. If a tube does break, either dispose of the entire tube shield (and remove the opposite
shield for proper balance) or safely dispose of the sample and broken glass and thoroughly clean and disinfect the
inside and outside of the tube shield. Additional tube shields are available for purchase from LW Scientific, Inc.
Motor and electrical maintenance: The E8 utilizes a PMDC motor and its bearings are permanently lubricated. It
should not need servicing for the life of the centrifuge. Likewise, the electrical components were designed for high
reliability and should not need regular service. However, if repairs should be needed, please contact LW Scientific,
Inc.
Because of the safety issues with high g-forces in a centrifuge, it is recommended that rotors and tube sleeves be
inspected every 6 months for corrosion and fatigue. If there is any indication of wear, the rotor and sleeves should be
removed from service. Contact LW Scientific for return instructions so the rotor and tube sleeves can be evaluated
by an LW Scientific technician for repair and replacement. It is also recommended that after 2 years of service, rotors
and tube sleeves be returned to LW Scientific for inspection. Following these procedures will ensure safety of lab
personnel as well as extend the life of the centrifuge.
