Designed for applications that require repeatable results and superior temperature
stability. These multi-purpose units are ideal for incubation and activation of cultures,
enzyme reactions, immunoassays, melting/boiling points, and a wide variety of other
laboratory procedures.
For best performance, the Mini Block Heater should be used in a stable environment.
The unit's environment should have no air currents, drafts or temperature changes
and it should not be placed in direct sunlight. The unit requires a stable electrical
supply that is free of voltage fluctuations. An unstable environment will adversely
affect the performance of the unit. For example, even minor air drafts or temperature
changes will adversely affect the unit's ability to maintain a stable temperature.
1. Getting ready:
a. Press the standby button to change the unit from standby mode. The
temperature display, time display will illuminate.
2. Setting temperature:
a. Press the up/down arrows under the temperature display until you reach the
desired temperature. Holding down either the up or down arrow will cause the
set temperature to change rapidly, a single pressing of either key will move
the set temperature by 0,1°C. When you release the button, the display will
blink off and then on, indicating the new set temperature has been accepted.
Once the set-point has been programmed and the keys are not being pressed,
press the on/off button under the temperature display to activate the heating
and time function. A green indicator light will illuminate next to the on/off button
indicating the heating function is on. The temperature display will show the
actual temperature. There are three (3) audible beeps to indicate the set-point
temperature has been reached.
b. Set-point temperature adjustments can be made without interrupting heating
using the up/down arrows under the temperature display. After the change
has been made and you release the button, the display will blink off and then on
indicating the new set temperature has been accepted.

c. To stop heating, press the on/off button under the temperature display.
d. Allow time for the temperature to stabilize. The actual temperature displayed
is the temperature at the bottom of the modular block. Once the displayed
actual temperature agrees with the set temperature, several minutes should be
allowed for the temperature to stabilize throughout the block evenly.
Overshoot protection: If the unit exceeds 130°C, the unit will automatically stop
heating.
3. Setting timed mode: Programmed time.
a. Press the up/down arrows under the time display until you reach the desired
time.
b. Time starts when the temperature is turned on. If a time is set the unit will run for
the selected time. When using the timer in conjunction with the heating function,
when the time display reaches zero (0:00), when using a programmed time,
four (4) audible beeps will indicate the time down function is complete. Both the
time and heating functions will shut off automatically and the time display will
default back to the set time. To repeat for the same time, simply depress the
temperature on/off button again.
c. Time cannot be interrupted without turning off the heater. To interrupt the time,
press the heater on/off button.
4. Setting time to zero (0:00) and continuous mode: Accumulated time.
a. Use the up/down arrows or press and hold both arrows to reach zero (0:00).
b. Pressing the heat on/off button will begin the time counting up. The up/down
arrows will become inactive while the heater is running. To stop timer, press on/
off button again..
5. Turning unit off:
a. To turn the unit off, press the standby button, the temperature and time displays
will be blank, the standby indicator light will turn on. To fully power down, unplug
unit.
