Ultra Centrifuge Instructions
Installation and User Manual
Introduction:
The Ultra-8 centrifuge is available in three models: the Ultra-8F (fixed speed), the Ultra-8V (variable speed) and the
Ultra-8 Select (4-speed selector).
The Ultra-8F is the lowest-cost unit, designed for blood separations at 3300 rpm’s only. The Ultra-8V will separate
blood at 3300 rpm’s, and can be slowed to separate other fluids at lower G-forces such as urine specimens as outlined
by C.L.I.A. regulations. The Ultra Select offers pre-set speeds at 800, 1500, 1800, and 3300 rpm’s for accuracy and
simplicity.
Features:
30 minute timer, on/off switch (indicator light), variable speed control (not on U8F), 8 tube capacity (3-15 ml), locking
lid, safety switch in lid (unlatching the lid turns the centrifuge off), one –piece metal housing, high impact plastic view
port allows for observation of samples and strobing for speed calibrations.
Installation & Setup:
7.
Remove the centrifuge from the shipping container and inspect for any possible shipping damage. If the
centrifuge appears to be damaged from shipping, please contact your distributor immediately.
8.
The large plastic tube shields (ITTS-15ML) are designed for large tubes up to 15 ml, and smaller tube
shields (ITTC-1375) are included for shipping shorter tubes (75 mm length). Special size rubber tube
cushions can be ordered from GIMA for a small cost. Verify that all tube shields are installed and
balanced (see /6 below).
9.
Verify that the power (timer) switch is in the “OFF” position and plug the line cord into an approved and
properly grounded 220V AC outlet. Do not insert specimen tubes at this time!
10.
Close the lid and latch, turn the centrifuge on, and turn the timer to 5 minutes. If there is a smooth
whirring sound and the unit accelerates with little or no vibration, your Ultra-8 centrifuge is ready to
operate. If there are loud or unusual sounds, or if you experience excessive vibration, DO NOT
OPERATE – Contact your dealer or GIMA.
11.
Spin only balanced loads. Make sure that all tube shields are filled with equal weight tubes. Tubes of equal
weight and size should be placed opposite each other. Use water-filled tube to provide balance. Proper
sample balancing will improve sample separation and will extend the life of the centrifuge. Out of balance
loads may break glass test tubes.
Care & Maintenance:
With proper care and maintenance, the Ultra-8 centrifuge will provide years of laboratory service. Please follow the
following recommended guidelines:
•
Use only quality test tubes. Lower quality glass tubes may fracture and release their contents into the tube
chamber, even under the normal vibrations and stress loads experienced in typical laboratory centrifugation.
•
Never force a tube into the tube shield. The tube shields were designed to hold the most common sized tubes,
Vaccutainers, and SST’s. Some plastic, conical, and glass test tubes are too large and should not be used in the
Ultra-8.
•
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 from GIMA.
•
Motor and electrical maintenance: The Ultra-8 utilizes a brushless induction-type 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 GIMA.
Warranty:
Your Ultra-8 model centrifuge is covered by a limited one year warranty on parts and labor. If the centrifuge or any of
its parts should fail during this period, simply contact GIMA for a “Return Merchandise Authorization” number for
repair or replacement. Any attempts to repair the centrifuge or replace any of its parts without authorization from GIMA
may void the warranty.
