What is a thermostatic tank?

A thermostatic tank, also known as a thermostatic tank, is a specialized device for heating or cooling in laboratories, KCS rooms, and analysis centers

This device will help stabilize liquid samples such as pharmaceutical, cosmetic or food samples,… Besides, the thermostatic bath is also the solution for those chemicals that are flammable, cannot be directly exposed to heat or with special chemicals that need to be handled in a thermal environment.

A thermostatic tank consists of a tank used to cool or heat a bath of liquid to a required temperature. Samples are usually contained in glass vials and placed in a bath to be heated or cooled.

Functions and uses of thermostatic bath

Thermistor has a fairly wide range of applications. This device can be used in reagent heating, molten substrates or incubated cell cultures, as well as being used to enable certain chemical reactions to take place under high temperature control. .

Most types of thermostatic tanks in laboratories today are equipped with a digital interface. This interface will allow the user to set the required temperature. The light will be on when the tank is working. Once the correct temperature is reached, the laboratory bath is switched on and off to maintain a constant temperature.

Another type of tank is a shaker thermostat capable of providing additional controls to allow the user to control the speed and frequency of shaking movements. Primarily used to mix two substances together, the shaker tank can be used as an alternative to other conventional tanks by turning off the shaking mechanism.

Construction of thermostatic tank

Most types of thermostatic tanks are usually made of heat-resistant glass, insulating metal or stainless steel. Structure of the device includes:

Propeller or agitator to circulate the water in the tank to maintain a uniform temperature during the heating process

Battery built-in thermometer or set a separate way to check temperature

Thermistor maintains the temperature

Controller for setting temperature

Safety controller

Principle, how to use a thermostatic bath

Types of thermostatic baths will usually work on the principle that the water temperature sensor of the Cu50 converts to a resistance value which is then amplified and compared with the amplifier. was integrated, then output a control signal, effectively controlling the average power of the thermoelectric tube and maintaining the water at a constant temperature. High temperature balance but no more than 100℃ is a good choice for a thermostatic tank.

How to use the thermostat correctly:

Fill the tank with clean water (preferably distilled water) to the desired level, then turn it on

Set the thermostat to the desired temperature and allow the water to gradually warm to that temperature.

Then check the temperature from the thermometer.

Classification of laboratory thermostatic tanks

In the lab we can see some typical types of thermostats below:

Cold water bath

Applicable for samples requiring high temperature homogenization, such as: Enzyme testing, or serology. The water will be circulated thoroughly during placement in the tank resulting in a more uniform temperature.

Recirculating thermostatic tank

Non-circulating thermostatic tank

shaking thermostat

This unit has additional control for the speed of shaking or moving the fluid around. This feature can be turned on or off. During microbiology practice, continuous shaking allows liquid cell cultures to grow continuously when combined with air.

Notes when using and storing the thermostat

Laboratory thermostats do not have to be filled with water all the time. The fluid used will depend on a variety of factors, including the range of temperatures required or the required viscosity of the fluid. And sometimes oil will be used in the tank instead of water. Thermostats can be dangerous to work with flammable substances, such as oil, so it’s important to take the best safety precautions, including using the tank on a surface. flat, stable.

In the process of using thermostatic tanks in particular and laboratory equipment in general, users need regular maintenance and correct techniques. Here are some notes and ways to maintain the bath in the laboratory:

Clean, clean and change the water daily for the thermostatic tank

Check, prevent salt in water from sticking on the heat probe, stirrer or thermometer.

After use, it should be cleaned to avoid mold growth.

The lid should be closed when not in use to prevent water evaporation and external contamination.

Check water temperature and thermometer in device, correct if incorrect.

It is recommended to fill the tank with water to the desired level and then turn on the machine

Adjust the desired temperature and regularly check the temperature from the thermometer.
