Water bath is a widely used testing chamber, which is typically preferred for incubation purpose in a microbiology lab and for quality testing of materials which are sensitive towards direct-heat. It helps to maintain a consistent temperature of the water for a required period of time and used for observing material behaviour in the raised temperature. It is also used to initiate a chemical reaction to occur once the water reaches a set level of temperature.

How does it work?

The chamber is first filled with a specific amount of distilled water and is constantly observed to check the temperature of the bath. It is recommended to keep a thermometer in the bath to record the temperature of the water efficiently. A digital controlling panel on the machine will help the operator to control the testing parameters. Usually, an indicator glows on the control panel as the user starts the machine which displays that the water bath is working. Once the set temperature is achieved inside, the machine automatically turns on or off in order to maintain the consistency in temperature for a long period of time. Most of the water baths (but not all) have a safety setting system that prevents the water from crossing the temperature limit. Once the water reaches the required level, the indicator glows on the control panel.

A typical Water Bath (Digital Model) is a rectangular, double-walled, stainless steel chamber. It is a digital equipment, wherein both the inside and outside body are made of high-grade corrosion resistant stainless steel. It is used to incubate samples in hot water at high temperatures required in textile and microbiology industries. It comes with a motorized stirrer for maintaining heating efficiency.

It can be used in any type of textile wet processing like merchandising, de-sizing, scouring, bleaching, optical whitening, dyeing, printing, etc., it is important to maintain standard temperature with regards to the duration of the process. It facilitates preparation of similar solutions and is hence, a must for any wet processing lab.

Key features you must look for:

  • A temperature control system through PT-100 sensor
  • Highly accurate test results under uniform temperatures in the chamber
  • Advanced digital microprocessor based PID temperature controller
  • Provision of set value (SV) and process value (PV) on temperature display
  • Inbuilt auto tuning function
  • Equipped with rapid heaters for uniform and homogenous heating and maintaining temperature inside the chamber
  • Integral water drain system
  • Inbuilt calibration feature with reference to master PID controller
  • Setting to RTD PT-100 sensor through advanced PID controller
  • Stirrer motor for precise stirring of sample inside the tank and for uniformity of temperature
  • Speed regulator for controlling the speed of stirrer
