1 Description of the product
1�1 Overview:
Exchangeble thermoblocks
Display Control panel
1�2 Explanation:
Control panel:
Program up to 9 complete programs with 30 program steps and temperature curves in total - exactly tailored to your application. The application variety is rounded out by the short mix function e.g. for vortexing as wel as interval shaking. The
direction of rotation is switchable by the software.
Display:
There is a constant overview of your process at any time. With the detailed information on the display
you always have an overview of the following values:
* Actual and set temperature
* Actual and set shaking frequency
* Actual and set time
* Program number, cycle, step
Exchangeble thermoblocks:
There are more than 40 exchangeble blocks. Quick and simple handling: they are simply inserted and xed on top of the
heating and cooling units. The blocks are suitable and exchangeable for all Thermo shakers and Block thermostats. Our
blocks have consistent outside dimensions of 14,5 x 10,2 cm. The usable area here is 12,5 x 8,5 cm. The height varies
with each block.

Temperature accuracy:
Every Hettich Benelux system is calibrated with a gauged high-precision tem-perature measuring device to temperature
accuracy and reproducibility. This calibration is performed at a room temperature of +20,0°C and with oil as a reference
liquid. Hettich Benelux reaches a very high accuracy by measuring the block temperature directly inside the block. It can,
however, not be avoided that the room temperature affects the sample temperature in case of a large temperature difference between room and block temperature. The anti-condensation plate reduces this effect. We recommend using the
anti-condensate plate BA 24 / BA 96 or the tempering tub BT 01 / BT 02. When setting a process time, please note that
the sample temperature is always reached a little later than the dis-played block temperature.
The TK 23 and the TH 21 are not be able to shake.
Sound level:
The noise that the device makes is caused by the cooling fan. The cooling fan runs faster as the device consumes more
power. If the device warms up or cools down to its set temperature, it will produce more noise than when it reaches the
set temperature.
This is designed to make the device as quiet as possible.

the mains.
Keep packaging materials away from children. Plastic can be a choking hazard to children. Please return the
packaging to an ofcial collection point.
9�2 Installation
The equipment can be used on a at and stable surface. Make sure the suction feet are clean and dust free before placing the device on the desired place. Test if the device is xed on the desired place by pulling it up. A clear “plop” sound
assures you that the surface is not porous.
Be ware that there are many blocks that are suited for the device. Please ensure that you adjust the mixing
speed of the device, to make sure that it remains at its place.
The device still could move because of the shaking motion. Make sure it is impossible for the device to fall
from the table.
Make sure that the ventilation openings of the device are not blocked. To ensure proper ventilation at all times,
a minimum distance of 10 centimetres on each side of the device is required.
9�3 Changeable blocks
At delivery, the changeable blocks are packed separately. Place the blocks on the tempering plates and take care of the
proper alignment of the central threaded bolt and the two small corner bolts ensuring that the block lays accurately on the
tempering plate. Then attach the block with the enclosed socket screw tightly at the bottom of the tempering plate to get
the block xed for shaking and to obtain even better temperature accuracy. Check the tight attachment of the block by
pulling it up
Never start the process without the block being tightly attached. Do always use two blocks for two-block systems, even if
only one of them is used. This ensures safety as well as a smooth shaking operation.

13 Troubleshooting
The display remains blank
Please check if the mains switch on the back side is switched on.
If it is switched on and voltage is present at the socket, check the micro-fuse and replace if required. (IEC 127-2/III, 250 V,
6.3 A time-lag).
This fuse and a spare fuse are located in the IEC-bushing (in which the connection cable is plugged). The fuse box can be
pulled out with a screwdriver.
The system does not cool, heat or shake as set
Check whether the display indicates the correct system type name at power-on. If not, please contact your local dealer or
the Hettich Benelux service de-partment.
There are excessive temperature uctuations
Check the seat of the changeable block by pulling it up. If it is too loose or if the block exhibits roughness, e.g. contamination, the heat / coolness is not transferred correctly.
Information on the capacitive touch display
The touch display reacts on nger pressure, even when wearing thin latex gloves, but not on stylos.
Due to its glass surface, the front panel is insensitive to dirt, chemicals and mechanical damage. Please avoid scratches in
the coating since they can cause malfunctions. Please take note of the following cleaning instructions.
