Shaking Water Baths

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 products of JULABO ensure safe operation when installed, operated, and maintained
according to common safety regulations. This section explains the potential dangers that may
arise when operating the circulator and also specifies the most important safety precautions to
preclude these dangers as far as possible.
The operator is responsible for the qualification of the personnel operating the units.
The personnel operating the units should be regularly instructed about the dangers involved
with their job activities as well as measures to avert these dangers.
