The water bath is an instrument used in the laboratory for carrying out serological, biomedical, and pharmaceutical tests at specific temperature ranges.

1. Water Bath
 The water bath is an
instrument used in the
laboratory for carrying out
serological, biomedical,
and pharmaceutical tests at
specific temperature ranges.
 normally used range
between room temperature
and 60 °C. Temperatures of
100 °C can be selected, using
a cover
 with chambers of a capacity
ranging from 2 to 30 liters.

3. Theory of operation
 Water baths are made of steel and are generally




covered with electrostatic paint with high adherence
and resistance to environmental conditions
One or more heating elements are used to heat the
water
Immersion type and External type heaters are used.
A thermostat or similar controlled used to turn off the
element when water reached to the predefined
temperature.
There are some stirring method to distribute
temperature evenly.

4. Installation and Safety
 Verify that the location selected is leveled
 Avoid placing the water bath where there are strong air
currents which can interfere with its normal operation
 Avoid the use of the water bath in environments where
there are flammable and combustible materials
 Always connect the equipment to an electrical outlet
with a ground pole to protect the user and the
equipment from electrical discharges

5. Maintenance
Monthly
Quarterly
Remove the water used for heating
2. Remove the thermal diffusion grid
located at the bottom of the tank.
3. Disassemble the circulator and clean to
remove scale and potential algae
present.
4. Clean the interior of the tank with a
mild detergent. If there is any
indication of corrosion, use substances
for cleaning stainless steel. Rub lightly
with synthetic sponges or equivalent.
Avoid using steel wool to remove rust
stains as these leave particles of steel
which could accelerate corrosion

Check the thermometer or
temperature controls every three
2. months using known standards.

6. 1.0 The water bath is not getting hot.
The temperature control
not set.
 Set the temperature control.
The element(s) is/are
defective.
 Change resistor(s).
The limit control is not
set
 Set the limit control.
