5. CAUTIONS

This unit uses a bench top universal power supply that provides 12 volts DC to
the unit. The power supply plugs into the AC line with the cord provided. Be
certain that the cord is not placed where it can be damaged by heat or traffic.

Also, the unit can spin the sample disk as high as 60 rpm. Be sure the sample
disk if secured to the rotator and that the samples are secured to the disk.

6. GENERAL DESCRIPTION

The Cole-Parmer Roto-Torque Rotator is supplied with the motor/control
housing, stand, power supply and AC line cord. However, the unit is used with
one of three rotating disks that are purchased as accessories. The rotator unit
contains a motor, speed control with ON/OFF detent fully counter-clockwise,
indicator LED, DC input jack, and a shaft coupler for the disks. The Multipurpose
disk (No. 07637-23) includes small clips, large clips and mounting hardware.

The Roto-Torque Rotator combines functional features with its attractive
packaging. It can be used for very low to moderate agitation. It has a stepless
electronic speed control, which can vary the speed from about 3 to about 80rpm.
Even with heavier loads on and around the rotating disk, the disk will have a
smooth rotation without cogging. The unit has an adjustable tilt housing that can
be set by the operator to the correct angle desired for a particular test.

The Multipurpose disk can accept different sizes of clips. They can hold test
tubes, flasks and bottles. Clips around the periphery of the disk are placed at an
angle. And the user may adjust the angle. Any test tube placed in this clip will
move through a figure 8 motion causing a sloshing effect and mixing of its
contents.

The unit can be tilted forward or backward to about 45 degrees. Stops are
placed on the stand to prevent the rotator module from tipping too far forward or
backward for safety.

7. ASSEMBLY AND GENERAL INFORMATION

Install the motor/control housing assembly on the base bracket using the top
slots in the sides of the base bracket. Be sure to orient the base so that the side
bracket with the pointer/stop pin on it is to the side of the base with the two
stopper-pins. It may be necessary to pull the sides of the base bracket apart for
this installation.

4

Place the fiber washer and the curved washer on the threaded shaft (side axle)
outside of the base bracket. Use the side knob on the threaded shaft (axle).
Determine the required tilt of the housing and tighten the side knob. The tilt
angle of the housing can be changed by loosening the side knob.

Now the rotator disk can be mounted on the shaft on the top of the unit. Be sure
to align the guide pin and the mounting hole, and then tighten the disk to the
shaft until snug. An Allen wrench can be used to tighten the screw more.

Two sizes of clip are supplied with the disk. They can grip diameters of 10 to
20mm. The clamping diameters can be varied somewhat by slightly bending the
clips. An extra large clip (20-25mm) and giant clip (20-40mm) are available as
accessories.

The clips can be attached on the periphery or the flat surface of the disk. Thirty
mounting holes on the periphery and sixteen holes on the front of the disk are
provided for the mounting clips.

8. SOME APPLICATIONS

The Rotator can be used for:
Micro-diffusions determinations
Semi-micro extractions
Washing precipitates
Blood reconstruction
Dissolving of separations from chromatography paper
Gas saturation of blood
Moderate agitation in tubes, flasks and bottles

9. OPERATING CHARACTERISTICS

The rotator comes with a powerful DC gear motor that provides high torque even
at low speeds. It is designed to run smoothly, but it is still a good idea to try to
balance the load on the disk. The dial graduations on the control are for
reference only and are not calibrated to any set speed. The speed control has
an OFF detent fully counterclockwise. This also turns-off power to the unit.-

Note: Cole-Parmer reserves the right to make improvements in design,
construction and appearance of this unit without notice.
