2.2.8 Sample racks
There are several racks available for working with the DancerPlus. All racks contain bores enabling each one to
be screwed to the shaking plate. You may also choose the FAST option to connect the rack to the shaking plate
without having to use screws.
The racks are manufactured from anodized aluminium. Flawless functioning of the device can only be guaranteed
if original racks are used.
Self-built racks or setups that are not approved by the manufacturer or its national representative
will result in the voiding of the guarantee on the shaking plate and drive.

The R0121 rack for the DWP (3 pieces) or microtiter plates are not suitable for the FAST option
for the shaking plate.
When the rack is removed, the temperature sensor must first be removed from the hole and laid
aside in order to prevent the PTFE sleeve of the temperature sensor or its cable from being bent
or scraped.
If the temperature sensor is bent, the sensor itself may become broken and the device will no
longer function as a result.
If the PTFE sleeve is scraped, this may cause a leakage which will prevent the vacuum pump
from being able to reach the final value. In both cases, the guarantee on a new temperature
sensor, its installation and potential transport costs will become void.

Page 19
2.3 Installation
2.3.1 Location
The DancerPlus must be structurally stable for operation.
In order to ensure a sufficient fresh air supply, the ventilation slots (Fig. 6 no. 1 or Fig. 8 no. 3)
must not be blocked or obstructed with materials, paper, a folder etc., and a minimum distance
of 20 cm from an impediment must be maintained. The fan should always work in parallel with
the IR lamp (Fig. 7 no. 2) when the lid is closed.
The DancerPlus and the vacuum pump shake when in operation, which means that these devices
must not be on the same working surface as, for example, a microbalance, microscope, HPLC,
sensitive analysis devices, sample and cell culture storage areas, etc.
2.3.2 Operation with inert gas, vacuum pump, cold trap
For operation with inert gas, e.g. nitrogen, the inert gas line is connected at the release inlet (Fig. 6 no. 3) in order
to ventilate or fill up the vacuum chamber (Fig. 7) during the vacuum relief process with inert gas. This is
recommended during the evaporation of solvents, e.g. ether, benzene etc. with a low flashpoint or ignition point.
Install a pressure reduction valve with a manometer featuring a display range of 0 bar to 6 bar
and set the pressure to 2 bar (29psi).
As nitrogen is heavier than air, open the cover carefully and slowly so that the samples in the
vacuum chamber remain shielded in the inert gas build-up.
The security guidelines relating to inert gas in general, and in particular following a power
interruption or defect, must also be observed.
Diaphragm and rotary vane pumps are all suitable for operation with the DancerPlus. We recommend that you
use a Vacuubrand® PC3003 Vario diaphragm pump for the careful constriction or evaporation of solvents. This
will allow pumping to be carried out at time-controlled gradients, as well as with automatic boiling pressure
detection and tracking. A rotary vane pump is better suited for the evaporation of solvents such as DMSO, or for
the drying of powders or silica gel.
A diaphragm pump and rotary vane pump with a switchover valve may be used for the
evaporation of various solvents and for different working processes.
We recommend pre-connecting a cold trap, e.g. the PoleStar, to aid the vacuum pump in the evaporation of
solvents. This not only saves time during the evaporation process, but also provides relief to the vacuum pump,
ambient air, the persons present in the area and the environment due to the hazardous substances being
effectively contained.
The vacuum pump should be installed opposite the PoleStar cold trap at a slight increase in height, and is
connected to the tube connection. The operating instructions of the PoleStar cold trap and the vacuum pump
must be observed.
2.3.3 When using a Vacuubrand® diaphragm pump and PoleStar cold trap:
Fit the external vacuum sensor (Fig. 9) with the corresponding fittings so that the sensor protrudes
from above with an angle of 45° ±15°; this will prevent condensation and liquid build-ups on the
sensor. This will result in an incorrect pressure measurement.
Fit the metal tube of the DancerPlus vacuum connection to prevent liquid build-ups or siphons in
the metal tube

Hettich AG, Seestrasse 204a, 8806 Baech, Switzerland Operator Manual_DancerPlus_EN_rev, 1.1
Page 20
2.3.4 When using a Vacuubrand® diaphragm pump without the PoleStar cold trap:
Fit the external vacuum sensor (Fig. 9) with the corresponding fittings so that the sensor protrudes
from above with an angle of 45° ±15°; this will prevent condensation and liquid build-ups on the
sensor. This will result in an incorrect pressure measurement.
2.3.5 When using a Vacuubrand® rotary vane pump and PoleStar cold trap:
Fit the metal tube of the DancerPlus vacuum connection to prevent liquid build-ups or siphons in
the metal tube. The outlet of the rotary vane pump contains oil particles; this is not permitted in
a cleanroom environment, i.e. the rotary vane pump must be installed outside the cleanroom. For
installation in a normal laboratory facility, we recommend extracting the rotary vane pump exhaust
air.
2.3.6 When using a Vacuubrand® rotary vane pump without the PoleStar cold trap:
The outlet of the rotary vane pump contains oil particles; this is not permitted in a cleanroom
environment, i.e. the rotary vane pump must be installed outside the cleanroom.
For installation in a normal laboratory facility, we recommend extracting the rotary vane pump
exhaust air. When solvents are evaporated with the DancerPlus, the mixture of gas, oil and air
constitutes an explosion hazard and the direct extraction of exhaust air is therefore mandatory.
Attention: The extraction may not be carried out via a normal exhaust system, as these are usually
not explosion proof; this means a special exhaust system is required.
2.3.7 Installation of the rack and shaking plate
Without the FAST option, the rack is screwed to the shaking plate; this ensures that the hole for the temperature
sensor is in the rear right area. Carefully insert the rack with the shaking plate into the vacuum chamber so that
all feet of the shaking plate fully fit into the corresponding recesses in the vacuum chamber (for the magnetic
drive). Insert the temperature sensor into the corresponding hole, see Fig. 3 and Fig. 4.
With the FAST option, the shaking plate is carefully inserted into the vacuum chamber with the already fitted rack
pins (see Fig. 2) so as to ensure that all feet of the shaking plate fully fit into the corresponding recesses in the
vacuum chamber (for the magnetic drive).
The rack is now carefully lowered over and parallel to the rack pins, ensuring that the temperature
sensor hole is in the rear right area and that the rack does not tilt against the rack pins.
During the initial commissioning, the DancerPlus must not be left unattended before it has
reached a steady state.
Please be aware that the devices described here are not explosion proof (they do not fulfil
guideline VBG 24 of the German Employer’s Liability Insurance Association). Explosive mixtures
of gas and air must not be present within the immediate vicinity of the device.
Significant dust formation or aggressive vapours in the environment of the DancerPlus may lead
to debris within the device’s interior, consequently causing short-circuiting or damage to the
electronics. Sufficient measures must therefore be taken to prevent significant dust formation and
aggressive vapours in the immediate vicinity of the device.
