Basic Data
The HLC by DITABIS Thermo Shakers and Block Thermostats are used for tempering and mixing of solutions in closed reaction tubes and plates. Please pay
attention that the target temperature of the samples should not exceed the
boiling point of the solution, which should be heated. Please consider this
when setting the target temperature via the software of the Thermo Shaker
or Block Thermostat. If there are any uncertainties regarding the liquids,
which should be heated or cooled, please contact DITABIS. The HLC by DITABIS devices are meant for indoor usage only. Please use only HLC by DITABIS
accessories or accessories recommended by HLC by DITABIS.
Safety
The systems comply with the standards and directives mentioned in the applicable CE declaration.
Please take note of the following safety measures:
Do only connect the system to an earthed mains power
socket of 230 V, 50 Hz.
Do not place hot blocks on inflammable or not heat-resistant
surfaces.
Make sure to only use containers in the block which are
suitable for the desired temperature range.
If liquid gets into the system, immediately pull out the plug
and contact our service department to ensure complete
safety.
Please do not touch or transport hot systems.
Contact with highly flammable fluids must be avoided.
The ventilation of the device must not be blocked. To ensure
the proper ventilation at all times please consider a minimum distance of 10 centimetres on each side of the device.
Damaged mains cable should only be replaced with equal
ones.

Warranty
All functions of the systems have been tested thoroughly. After that, the
system and the accessories were packed carefully in perfect condition. If,
however, any damages or defects are detected during installation or
setup, please contact your local dealer or the DITABIS service department.
The DITABIS contact information can be found at www.ditabis.de (see also
our Terms and Conditions at www.ditabis.com). If used under normal laboratory conditions according to the Operating Manual, DITABIS grants a warranty
of one year, starting with the day of shipment.
Disclaimer of warranty
In case of unspecified use of the device, the manufacturer assumes no responsibility.
Important information
This manual complies with the standards and directives mentioned in the EN
DIN 61010-1 Norm. IQ, OQ and PQ documents are available on request.
The systems are provided with a high-precision self-optimising
temperature controller. Due to the self-optimisation it might occur that the set temperature is exceeded in individual cases.
Please note, that by heating your samples dangerous gases may
be emitted. In this case, the device must be used with an extractor hood.
If the ThermoMixers are operated with a high shaking frequency,
the vibrations of the system might transmit to the underground.
Please do consider this when placing the system.

Contact with highly flammable liquids must be avoided. The exchangeable block may be hot.
The ventilation of the device must not be blocked. To ensure the
proper ventilation at all times please consider a minimum
distance of 10 centimetres on each side of the device.
Environmental conditions
The ideal area of operation of the devices is achieved at 80% relative air
humidity at most and lays between +3°C - +50°C ambient air temperature.
This range should not be underrun or exceeded.
Temperature accuracy
Every HLC by DITABIS system is calibrated with a gauged high-precision temperature measuring device to temperature accuracy and reproducibility. This
calibration is performed at a room temperature of +20,0°C at 10 different
temperature calibration points and oil as a reference liquid. HLC by DITABIS
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 displayed block temperature.

First Steps
Setup
Plug the mains cable in the IEC socket on the back of the system and connect
it with the mains power 230 V, 50 Hz via a Schuko socket. Please make sure
that you are using earthed mains power sockets.
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
fixed 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.
Switch on the system with the mains switch on the back of the system. The
start menu will be displayed. The green LED turns on, on the right sight of the
touch panel, as soon as a process is running.
