V. Cautions
Mixing
The RT10 is a variable speed, rotating mixer. It can vary speeds from about 4 to about 50 rpm. The
speed control is open loop without a speed control feedback system. Be sure to monitor the speed setting
from time to time to be sure your samples are mixed correctly. The speed control has an off detent fully
counterclockwise. When turned on, the rotating speed will increase as the control is turned clockwise.
Electrical
These units operate on 12 volts dc from an external power supply provided. There are two power supplies
for this unit. One takes inputs of 115VAC, 60Hz, and the other 230 volts AC, 50Hz . Be certain that your
voltage matches the unit. Check the voltage on the bottom label for the voltage setting on the unit. Take
the normal care and precautions one would use with any electrical appliance. The units are supplied with
an external power supply for the country of use.

VII. Installing the Tube Racks
The RT10 is supplied with a 4-sided rack for holding 50-0.5ml centrifuge tubes and 48-1.5ml or 2.0ml
centrifuge tubes. The rack has 4 covers, one for each side of the rack. They are provided with stainless
steel pins in them to couple the cover to the magnets in the rack which keeps the tubes from falling from
the racks as they rotate. The covers should be placed with the pin flush-mounted side down when using
tubes with snap-on caps. For screw down caps on tubes, flip the cover over. Additionally, there are 2
accessory racks available. One for 16-15ml centrifuge tubes (RT10-100), and the other for 6-50ml
centrifuge tubes (RT10-101).
To mount the rack provided, or either of the accessory racks, open the thumb screw on the rod holding
the rack so that the hole in the end of the rod is clear. Then be certain the screw at the end of the metal
chassis is backed-out to be flush with the chassis. Carefully lower the rack into the chassis and place the
hole on the end of the rod with the screw onto the motor shaft sticking out of the motor housing. Lower
the other end of the rod to align it with the screw on the other end of the chassis. Turn the screw opposite
the motor housing until it is fully into the hole on the rod. Next, align the thumbscrew with the flat side of
the motor shaft and tighten the thumbscrew on the rod to the shaft of the motor. Do not over-tighten. It
need only be snug. The mounting is complete.

VIII. Cleaning and Maintenance
This unit is subject to spills. They should be wiped off quickly to prevent discoloration of the plastic tube
rack. Wipe spills with a soft cloth or paper towel. If a cleaning solution is necessary, use a mild soap or
detergent solution and a soft cloth. Be sure not to use solvents. They could damage the plastic.
Maintenance
There is no preventative maintenance required on these units other than to keep them clean. All
components are solid state and will work until they fail. If they fail, they can be replaced easily. A simple
inspection should be done whenever the unit is to be used. This simple inspection should include:
1. Checking that the AC cord is not frayed or burned.
2. Checking that the unit is not dirty to a point where proper performance is impaired.
3. Be certain to store the unit properly, when not in use, in an area that will not have items placed on top of
the unit, and covered in a way that will keep dirt and other foreign bodies out of the unit..
