Vortex Mixer Introduction
Your Vortex Mixer is ready for most one-handed applications. The Vortex Mixer operates by mixing tubes just prior to testing.
Operating Tips
These units are not intended for continuous use over extended periods of time. A built-in temperature sensor will prevent the unit from
overheating by shutting the motor down. If this occurs, allow the motor to cool down and the unit will be able to resume normal operation.
Decrease the duration of the time unit is used between rest periods.
See page 10-11 for 'Head/Accessory Installation Instructions'.
Fixed Speed Vortex Mixer Operating Instructions
The Fixed Speed Vortex Mixer runs only at 2500rpm.
1. Plug the power cord into a properly grounded outlet. The unit is now on and in a standby mode.
2. The vessel you are using must be pushed down on the head attachment to achieve motion. To get the desired mix, vary the angle of
contact and pressure against the head.
3. The mixer will return to standby mode when the vessel is lifted off the head.
4. The unit can become warm to the touch with constant use. There is nothing wrong with it. At high performance settings the motor (UL
recognized component) simply puts out more heat. IMPORTANT: DO NOT use large accessories on the Fixed Speed Vortex Mixer. This
unit is designed for use with cup head or 7,6cm head with 7,6cm rubber head cover only.
5. To completely cut off power to the unit, disconnect the power cord from the wall outlet.
Analog Vortex Mixer Operating Instructions
1. Make sure the 3-way rocker switch is in the center, off position. Plug the power cord into a properly grounded outlet.
2. For continuous operation, push the rocker switch to the right, on position. For intermittent/touch operation, push the rocker switch to
the left, auto position.
3. In either case, turn the speed knob to 1. In the on position, you will see the head in motion immediately. In the auto position, the vessel
you are using must be pushed down on the head attachment to achieve motion. To get the desired mix, vary the speed, using the speed
knob, and/or vary the angle of contact and pressure against the head.
4. When finished with either continuous or intermittent operation, return rocker switch to the center, off position.
5. The continuous, on mode is for the larger accessories. In continuous on mode, DO NOT run the unit above 900rpm (analog speed
setting of approximately 5).
6. The intermittent, auto mode is intended for short mixing times of one (1) minute or less at full speed. A rest period of two (2) minutes
is recommended to minimize the possibility of overheating the motor. The unit can become warm to the touch with constant use. There is
nothing wrong with it. At high performance settings the motor (UL recognized component) simply puts out more heat. IMPORTANT:
When using larger accessories (Insert Retainer with foam inserts or Ampule Tube Holders), DO NOT run the unit above 900rpm, (analog
speed setting of approximately 5). UNIT DAMAGE WILL OCCUR.
7. To completely cut off power to the unit, disconnect the power cord from the wall outlet.
NOTE: Actual speed is subject to operating conditions and application. When selecting the ideal analog speed setting for your application,
please evaluate loading and duty cycle as these may impact the unit's actual motor speed.
