Laboratory Digital Water Bath

A laboratory water bath is a constant temperature equipment which is used for providing heat to the devices which need heat. It is used for keeping water at a constant temperature for the incubation of samples in a laboratory.

Working Principle – The sensor in a digital water bath converts the temperature of water to a resistance value, which is then amplified and compared by an integrated amplifier. After that, it outputs a control signal that effectively regulates the electric heating tube’s average heating power and keeps the water at a consistent temperature.

However, a Laboratory water bath is an excellent option for balanced high-temperature heating.

How to Use Laboratory Water Bath

Laboratory water baths are used for heating samples. Heating flammable chemicals, maintaining cell lines and that could catch fire if left near an open flame are two applications of a Laboratory water bath. A laboratory water bath comprises a stainless-steel chamber containing the water and samples, a heating unit and a control interface. Moreover, Additional functionality is provided by other types of water baths, such as circulating water baths are used for the maintenance of a more consistent temperature and shaking water baths are used to keep the samples moving while they are heated. 

There is an inbuilt anti-corrosion circulating pump in the digital water bath which provides a constant heat source for the rotary evaporator and glass reactor. The superior cold rolled steel sheet spraying plastics are used to make the shell of the Lamphun GY series circulating water bath, while the electrically heated tube functions in accelerating the heating of the conduction oil. 

Moreover, the liner of the water bath digital is made of imported stainless steel.

However, Laboratory water baths manufactured by Effective Lab India are protected by heat insulation cotton. Effective Lab India uses a smart PID constant temperature heating device and a double-screen LED temperature controller. This temperature controller is helpful for the accuracy of temperature control and controllable output flow.

While choosing a Laboratory water bath, you should have to consider the following things.

  • Capacity
  • Range
  • Cooling option
  • Ease of cleaning
  • It’s type. Shaking or Circulating
Types of a Laboratory water bath

There are two types of laboratory water baths.

  • Circulating water bath
  • Shaking water bath
  • Circulating Water bath

It is also known as a stirrer. It is an ideal water bath for applications where consistency and uniformity of temperature are critical. Examples include; serologic and enzymatic experiments. In circulating water baths, water is thoroughly circulated which results in a more uniform temperature.


  • Shaking water bath

Shaking water bath includes the controls of shaking. The shaking function moves the liquid around. Moreover, you can also turn off or on the shaking feature. In microbiological practices of a shaking water bath, liquid-grown cell cultures grow to constantly mix with air.

In addition, the following are some key benefits of a shaking water bath.

  • Convenient bath drains
  • User-friendly operation
  • Bright LED display
  • Shaking frequencies that are adjustable
  • Lift-up bath cover
  • Warning
  • Cut off protection for low/ high temperature


How to operate a water bath

The laboratory water bath is operated by:

  • First connect the water supply
  • Make sure the level of water is sufficient for pouring the heating element
  • Switch the main power supply ON.
  • If you want to set the temperature press the SET key to set the temperature.
  • There is a temperature sensor which maintains the set temperature during the use of a water bath.
  • At the end, switch off the main power supply and main of the water bath.
