Chillers, a water bath and a circulation bath

At present there are numerous laboratory equipment that facilitate the processes carried out in these places, including: chillers, circulation baths and a water bath.

What is a laboratory chiller?

A chiller is a laboratory equipment used to remove heat from a product or process. This equipment acts as a heat exchanger, in other words, it cools using a contact surface through which the hot material passes. In the past, laboratories used cold water, ice, dry ice, or liquid nitrogen for cooling. Chillers are easy-to-use equipment and highly accurate, which is why they have become quite popular in recent years.

Types of laboratory chillers

  • Water chillers.
  • Air chillers.

The difference between each of them lies in their capacitor. In a water cooler, the water is responsible for cooling the coolant. In air coolers, ambient air is used to change the phase refrigerant. These have the condenser outside or inside the housing.

What is a water bath?

A water bath is a laboratory equipment consisting of a container filled with hot water. The water bath is used to incubate samples in water at a constant temperature for a long period of time.

Applications include reagent heating, substrate melting, or cell culture incubation. It is also used to allow certain chemical reactions to occur at high temperatures.

Different types of water baths are used depending on the application that is needed. For all water baths, it can be used up to 99.9 ° C. When the temperature is above 100 ° C, alternative methods such as oil bath, silicone bath or sand bath can be used.

Types of water baths

  • Circulating water baths: Circulation baths are ideal for applications where temperature uniformity and consistency are critical.
  • Non-displacement water baths: This type of water bath relies primarily on convection rather than water that is evenly heated.

What is a circulation bath?

Heating circulation baths with a stainless steel bath allow temperature control of internal and external thermoregulation tasks. Items can be directly thermoregulated by placing them in a thermostat bath and control of externally connected applications is also possible.

It is thermostatic equipment used in chemical research laboratories to transfer heat indirectly, by thermal convection, to a sample that requires analysis. Thanks to these equipments, the heat transfer is carried out in a uniform way to the sample.
