Water BathThe 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.

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.

Installation and SafetyVerify that the location selected is leveledAvoid 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

MaintenanceMonthly Quarterly1. Remove the water used for

heating2. 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

1. Check the thermometer or temperature controls every three

2. months using known standards.

1.0 The water bath is not getting hot.

The temperature control not set.

The element(s) is/are defective.

The limit control is not set

Set the temperature control.

Change resistor(s).

Set the limit control.
