Water Bath

Laboratory Water Bath is a device used in laboratories to incubate samples in water maintained at a constant temperature over a long period of time. It is ideal for handling tasks of conducting experiments in different industries. These baths work above 100°C and need the presence of liquid for their operations. Further, the baths that work below ambient come with an internal/ external cooling system and those working below freezing water point come filled with a suitable anti-freeze solution. The variation in the range of Laboratory baths includes- Unstirred water baths, Stirred water baths, Shaking water baths, Cooled water baths, Boiling water baths and Cooling circulators. For durable performance, these Laboratory baths have stainless steel interiors with chemically resistant plastic/ epoxy coated steel exteriors.


Double-walled in construction, inner chamber SS and outer made of M.S. with powder coating, temperature range from 5°C above ambient to 95°C accuracies 2°C.  Capillary type thermostat for temperature control, top lid with concentric rings made of stainless steel, the gap between the inner and outer chamber is filled with glass wool insulation to minimize heat loss. An immersion type heater should be provided. Long-lasting elements Concentric rings to use flask from 50 ml to 500 ml capacity.

All water baths have a digital or an analogue interface to allow users to set the desired temperature. Utilizations include warming of reagents, melting of substrates or incubation of cell cultures. It is also used to enable certain chemical reactions to occur at high temperature. Water bath is a preferred heat source for heating flammable chemicals instead of an open flame to prevent ignition.


  • Water Bath Rectangular Single Walled is made of Heavy Gauge Stainless Steel with Concentric rings.
  • Water Bath Rectangular Single Walled fitted with Heating Element for uniform heating throughout.
  • Applied in research laboratories, Bio-Chemical industries and many other industries.


The water bath has evolved from a simply heated vessel to a precision instrument that is carefully calibrated and engineered to offer accuracy and reliability. Recently, waterless lab baths using small beads instead of water have become popular. Waterless baths avoid the contamination that can be a problem with traditional water baths, use less energy, and have a reduced risk of causing burns or injury.


  • Do not start the heater if there is no water in the Water Bath so the water bath should be filled with purified water only.
  • Always check the water bath to see if it is turned on, set at the right temperature, and filled with water. If you are using the water bath for an experiment you should check the temperature frequently to make sure that the water bath is maintaining the proper temperature.
