3. General information

MM-1000 Overhead stirrer Multi Mixer is designed for mixing solutions of different

viscosity.

Multi Mixer MM-1000 provides three types of motion: 1) rotational motion, 2)

reciprocal motion and 3) vibro motion, according to the microprocessor protocol. The

protocol enables making not only programs that include mixing motion of one particular type,

but also programs that alternate mixing motions of different types cyclically.

Rotational motion

Simple even rotation with an option of shifting direction (clockwise/counter

clockwise) after set time. The speed adjustment range is from 40 to 1000

rpm with 10 rpm increment. The motion time can be set in 0 to 250 s range

or non-stop.

Reciprocal motion

Reciprocal motion direction changing, limited by the turning angle. The

turning angle adjustment range is from 0° to 360° with 30° increment. The

speed is the same as set for rotational motion. The motion time can be set in

0 to 250 s range or non-stop.

Vibro motion Intensive mixing at high speed with small adjustable turning angle. The

turning angle adjustment range is from 0° to 5° with 1° increment. The motion

time can be set in 0 to 5 s range or non-stop. Reciprocating and Vibro motion

types can be replaced by a pause.

These 3 motions are combined in a cycle

and can be used:

separately (only 1; 2; or 3);

in combinations by two;

all three in one cycle (fig. 1).

A timer with the working range from 1 min to

96 hr is used to control the total time of operation.

By combining the provided motion types a

researcher gets unlimited options for choosing the

mixing parameters.

Apart from the unique operation modes, MM-1000 Multi Mixer offers user-friendly

interface, which provides options not only for changing the program during the operation, but

also for simultaneous control over different steps of mixing protocol realisation.

The external power supply ensures the electrical safety of the device.

5. Operation

5.1. Connect the external power supply to the mains.

5.2. Dip the stirrer inside the vessel with the liquid being mixed. The stirring element

should be completely dipped into the liquid.

5.3. Turn on the red power switch on the front panel. Display shows following indications:

Upper line: rotation speed (fig. 3/2), reciprocation angle (fig. 3/4), vibration angle (fig.

3/5), overall timer (fig. 3/7);

Lower line: rotation, reciprocation and vibro timers (fig. 3/1, 3/3 and 3/6), status

(STOP, fig. 3/8).

5.4. Set the required program and operation time (see section 6. Program setting).

5.5. Press the Run Stop key (fig. 3/11) to start the program.

5.6. The stirrer motion will begin and the corresponding indication, RUN (fig. 3/8) and the

changing time values (fig. 3/1, 3/3, 3/6 and 3/7) are be shown on the display.

5.7. If the overall operation time is not set and the Time indicator (fig. 3/7) shows 0:00,

pressing the Run Stop key will start continuous operation of the unit until the Run

Stop key is pressed again.

5.8. If the operation time is set then the unit will stop after the set time interval elapses.

Flashing indication STOP (fig. 3/8) is shown on the display and a repeating sound

signal for the end of operation is heard. Press the Run Stop key to stop the signal.

5.9. Press the Run Stop key to repeat the preset program.

5.10. The unit can be stopped at any time during operation before the set time elapses if

necessary by pressing the Run Stop key. Pressing the Run Stop key again will start

the program from the beginning (timer will be restarted).

5.11. After finishing the operation, turn off the power switch.

5.12. Unplug the external power supply from the mains.

6. Program setting

6.1. The program consists of cycles. Each cycle includes motions of three different types

(rotational, reciprocating and vibro) set one after another with the duration from 0 to

250 seconds for rotational and reciprocal motion types and from 0 to 5 seconds for

vibro motion.

6.2. Changing parameters. Press the Select key (fig. 3/9) to choose the parameter to

change, each consecutive press activates the next parameter in cycle. Active

parameter is flashing. Use the ▲ and ▼ keys (fig. 3/10) to set the necessary value.

Pressing the key for more than 2 s increases value changing speed.

6.3. All parameters except overall timer can also be changed during the operation. Unit

automatically saves and applies changes to the current work program.

6.4. Following parameters are available: rotation and reciprocation speed, reciprocation

and vibro turning angle, time for each motion type and overall operation timer.

6.5. Skip a motion. If the time for a type of motion is set to zero (indication OFF), this

type of motion will be skipped in the cycle.

6.6. Pause. If the turning angle for reciprocating or vibro motions is set to zero (indication

0), unit will interpret this as a pause. The stirring element will not move in this mode

during the operation and the overall timer will be counted down.

6.7. The overall timer (fig. 3/7) is used to control the operation time. The timer can be set

for the period from 1 min to 96 hours (increment 1 min). If the timer is set to 00:00,

unit operates non-stop, see 5.7.

6.8. Table 1 shows possible motion combinations in the cycle.

6.9. Further examples illustrate program setting for both separate motions and their

combinations in the cycle.

6.9.1. Rotational motion. Set the speed (40-1000 rpm, fig. 3/A) and time (1-250 s, fig. 3/B)

of rotational motion. Turn off reciprocal andvibro motions by setting their motion times

to zero (indications OFF, fig. 3/C and 3/D).

MM-1000 is programmed to change the direction of rotation when the motion timer is

restarted, i.e. if the rotation time is set to 30 s, then the direction is changed every 30

s as shown on figure 4, where positive RPM is clockwise motion and negative -

counter clockwise.

Figure 3. Figure 4.

6.9.2. Rotational + Reciprocal + Vibro motions. Set the speed (40-1000 rpm, fig. 5/A)

and time (1-250 s, fig. 5/D) of rotational motion. Set the angle (30-360º, fig. 5/B) and

time (1-250 s, fig. 5/E) of reciprocal motion. Reciprocal and rotational motions have

the same speed. Set the turning angle (1-5º, fig. 5/C) and time (1-5 s, fig. 5/F) for

vibro motion. Graph in figure 6 shows motion in this mode.

Figure 5. Figure 6.

6.9.3. Rotational + Reciprocal motions + Pause. Set the speed (40-1000 rpm, fig. 7/A)

and time (1-250 s, fig. 7/D) of rotational motion. Set the angle (30-360º, fig. 7/B) and

time (1-250 s, fig. 7/E) of reciprocal motion. Reciprocal and rotational motions have

the same speed. Set the turning angle of vibro motion to zero (fig. 7/C). Set the time

of vibro motion (1-5 s, fig. 7/F) - this is the duration of pause. Graph in figure 8 shows

motion in this mode.

Figure 7. Figure 8.

6.9.4. Vibro motion + Pause. Turn off Rotational motion by setting time of rotational motion

to zero (OFF, fig. 9/C). Set the turning angle of reciprocal motion to zero (fig. 9/A)

and set the time for reciprocal motion (1-250 s, fig. 9/D) - thisis the duration of pause.

Set the turning angle (1-5º, fig. 9/B) and time (1-5 s, fig. 9/E) for vibro motion. Graph

in figure 10 shows motion in this mode.
