Operating manual
1. Intended use
JULABO shaking water baths have been designed for temperature application to specific fluids
in a bath tank. Fastened on the shaking carriage, samples contained in a sealed container can
be brought to the desired temperature and simultaneously agitated.
JULABO water baths are not suitable for direct temperature control of foods,
semi-luxury foods and tobacco, or pharmaceutical and medical products. Direct
temperature control means unprotected contact of the object with the bath
medium (bath fluid).
1.1. Description
JULABO shaking water baths of the series SW22 and SW23 are ideally suited for laboratory
applications and research in the fields biology, biochemistry, pharma- cology, chemistry and
general medical technologies. They are likewise suited for routine laboratory tasks and long-
term unattended operation. The JULABO shaking water bath SW 23 with constant bath liquid
circulation, ensures a constant water temperature with a maximum deviation of 0.02 C .
Julabo shaking water baths feature a stainless steel bath containing heater, temperature
sensor and the overtemperature protection safety element. The shaking carriage is totally
removable.
The units are operated via a water protected foil keypad with integrated mains switch.
Microprocessor technology enables selection and storage of different temperature
values and operating times, and display of them in the LED-MULTI-DISPLAY. The self-
optimizing electronic PID-control circuit automatically adjusts the heat supply to the value
required by the bath.
The RS232C port permits modern process engineering without additional interface,
directly on-line, from the waterbath to your application equipment.
The overtemperature protection is a safety feature with a fixed safety value of 105 C. It
functions independent of the regulator circuit.
2. Operator responsibility – Safety instructions

The installation site should meet the following conditions:
1. The base of the installation site should be level to ensure
proper functioning of the safety features.
2. The laboratory table, for example, should be sturdy
enough, to where the shaking frequency cannot cause
vibration of the table. Consider that the masses moved
may be in the order of several kg.
Keep a wall distance of minimum 80 mm.
Do not cover the ventilation openings on the floor and
rear side of the bath.
Installing and removing the shaking carriage:
Holding screw (17) can be removed without the use of
tools. Retain plastic washers (18) on both sides of the
push rod.
The shaking carriage can be completely removed.
Samples can be added to the carrier trays while outside
of the bath.
Then put the shaking carriage back into place. Use the
holding screw and plastic washers (18) to screw the
push rod onto the shaking carriage (15).
Tighten the holding screw securely.
Caution:
The shaking frequency may cause a laboratory table to oscillate.
At operation, the vibration may cause items on the table top to fall off under
extreme unfavourable circumstances.
Carefully choose the setup location.
Shaking frequency is adjustable. After readjusting shaking frequency,
always observe other objects near the shaking water bath and remove them
to a different location if necessary.

Caution:
Potential hazards from the samples
Proper use of shaking water baths includes immersion of samples contained in
test tubes, Erlenmeyer flasks, or other containers for the purpose of controlling
their temperature.
We do not know which substances are contained within these vessels.
Many substances are:
inflammable, easily ignited or explosive
hazardous to health
environmentally unsafe
i.e.: dangerous
The user alone is responsible for the handling of these substances!
Always properly seal all sample containers.
Notice:
There is a danger of electrochemical oxidation or corrosion when using
test-tube racks or samples made of non-ferrous metal.
Avoid using these types of racks or samples.
Use only original JULABO test-tube racks.
5.2. Bath liquid
Recommended bath fluids: soft/decalcified water.
Caution:
Poor water quality may result in corrosion in the bath.
The quality of water (tap water) depends on local conditions.
Due to the high concentration of lime, hard water is not suitable for
temperature control because it leads to calcification in the bath.
Ferrous water can cause corrosion - even on stainless steel.
Chloric water can cause pitting corrosion.
Distilled and deionized water is unsuitable. Their special properties cause
corrosion in the bath, even in stainless steel.
JULABO takes no responsibility for damages caused by the selection of an
unsuitable bath fluid.
Please contact JULABO before using other than recommended bath fluids.
Do not use flammable bath fluids!

Preparations

5.3. Filling / Draining
Filling:
Maximum filling level: 6 cm below the bath rim
Minimum filling level: 7 cm (level approx. 3 cm above
surface (16) for the placement of items/fixtures)
Note:
The working filling level depends on size and number of the
items (fixtures) to be placed inside.
Fill to minimum level only. Insert the complemented shaking
carriage and correct the filling level (adding or removing liquid)
as required
Use the water bath cover to keep temperature losses to a
minimum:
Lift-up Makroloncover see page 20
Draining:
Switch off the shaking water bath with the mains switch and
move the equipment to the table edge.
Place a suitable collecting bucket or tub underneath the
equipment for draining the used liquid.
To drain the liquid open the dainage screw (11) on the side
of the water bath.
After the liquid has been fully drained, securely tighten the
drainage screw (11) again.
Warning:
There are thermal dangers when opening the bath cover:
Burn, scald, hot steam, hot parts and surfaces that can be touched.
Do not drain the bath fluid while it is hot!
Check the temperature of the bath fluid prior to draining
(by switching the unit on for a short moment, for example).

5.4. Maintaining a constant water level / Counter cooling
For cooling tasks near the ambient air temperature the liquid
level/cooling set can be used for counter cooling.
By special pipe routing, cool faucet water is continuously
supplied to the water bath, while at the same time, the heated
water is drained via the overflow connection of the
Level/Cooling set.
A specific water flow rate of 100 ml/minute is sufficient to
compensate for the characteristic temperature.
Caution:
Securely attach all tubing to prevent slipping.
Observe the laws and regulations of the water distribution company valid in the
location where the unit is operated.
Use of the liquid level/cooling set for a continuous supply of
faucet water:
1. to keep the water level constant, especially for applications
up to the boiling point (supply of faucet water only in the
amount of evaporation losses).
2. for countercooling of cooling tasks near the ambient
surrounding temperature (cool faucet water is continuously
supplied to the water bath, while at the same time, the
heated water is drained via the overflow connection of the
liquid level/cooling set).
