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, pharma­cology, 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-MULTI­DISPLAY. 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 to DIN 12876-1: 2000 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.

5

Operator responsibility – Safety instructions

 Make sure all persons tasked with operating, installing, and maintaining the unit have

read and understand the safety information and operating instructions.

 When using hazardous materials or materials that could become hazardous, the unit

may be operated only by persons who are absolutely familiar with these materials
and the unit. These persons must be fully aware of possible risks.

If you have any questions concerning the operation of your unit or the information in
this manual, please contact us!

Safety recommendations for the operator

 You received a product conceived for industrial use. Nevertheless, avoid strikes to

the housing, vibrations, damages to the keypad foil (keys, display) or contamination.

 Make sure the product is regularly checked for proper condition. Regularly check (at

least every 2 years) the proper condition of the mandatory, warning, prohibition and
safety labels.

 Take care that the mains supply features a low impedance to avoid any negative

affects on the instrument being operated in the same mains.

 This unit is designed for operation in a controlled electromagnetic environment. This

means that transmitting devices (e.g. cellular phones) should not be used in the
immediate vicinity. Magnetic radiation may influence other units with components
susceptible to magnetic fields (e.g. a monitor). We recommend to keep a minimum
distance of 1 m.

 Permissible ambient temperature: max. 40 °C, min. 5 °C.
 Permissible relative air humidity: 50 % (40 °C).
 Do not store in an aggressive atmosphere. Protect from contaminations.
 Do not expose to sunlight.

Appropriate Operation

Only qualified personnel is authorized to perform configuration, installation,
maintenance and repairs of the water bath.
Routine operation can also be carried out by untrained personnel who should however
be instructed by trained personnel.

Use:

Insufficient ventilation may result in the formation of explosive mixtures. Only use the
unit in well ventilated areas. The unit is not for use in explosive environment.

JULABO water baths have been designed for temperature application to water in a bath
tank.

Shaking Water Baths

The bath may not be filled with flammable materials. Fire hazard!
Only use non-acid and non corroding bath fluids.

When using hazardous materials or materials that could become hazardous, the
operator must affix the enclosed safety labels to the front of the unit so they are highly
visible:

If this unit is intended for use within the United States of America, all 3 warning labels
must be affixed to the housing of the unit prior to use.
Directions for the positioning of the individual warning labels are enclosed with the
warning labels included in the delivery. Warning labels must be easily visible to users.
