Circulated Water Bath (Built-in pump) TWB-24D-CP
In contrast to an uncirculated water bath, a circulated water bath uses a pump to circulate the water within the bath, ensuring that the temperature is consistent across the entire bath.
This Australian made digital heated water bath features an in-built pump so no additional external circulator (Unistat) is required.
Circulated laboratory water baths offer several advantages over uncirculated water baths. First, they provide more precise and uniform temperature control since the circulating water helps distribute heat evenly throughout the bath. They are also less likely to develop temperature gradients or hot spots. In addition, circulated water baths can be used for a wider range of applications, including highly precise temperature control, such as DNA amplification by polymerase chain reaction (PCR).
Circulated water baths are commonly used in a wide range of laboratory applications, including in chemistry, biology, and biotechnology. They are useful for a variety of tasks, such as incubating cells, thawing frozen samples, or conducting chemical reactions at a specific temperature.
The TWB-24D-CP is available in 24L size only and has a perforated false floor that sits above the heating element to protect your samples from directly contacting the heater. Convenient carry handles assist with moving the bath if needed. A simple-to-use drain for when the time comes to remove the water and clean the tank.
Water baths have a wide range of applications in various fields, including biomedicine, life sciences, and industry. They are also commonly used in commercial kitchen cooking methods like Sous Vide. Some specific applications of water baths include sample thawing, bacteriological examinations, reagent warming, coliform determinations, and microbiological assays.
Thermoline's laboratory water baths are trusted for their consistency in delivering outstanding performance and reliability in the lab. If you have specific requirements for your laboratory water bath, such as a specific size or function, we can customise a water bath to suit your exact needs.

We are committed to providing whatever support our customers need, wherever they are in the world. If you can't find your solution in the below FAQs or Knowledge Base, please contact our friendly support team.
- How do I control temperatures at or below ambient?
- To achieve temperatures at or below ambient will require refrigeration of the bath. Thermoline has a wide range of refrigerated water baths to suit your needs. The TU3 is a heat-only device that controls temperatures +5°C above ambient temperature.
- What are laboratory water baths used for?
Laboratory water baths are a type of laboratory equipment that are used for a variety of applications, including:
Warming and thawing samples: Water baths can be used to quickly and uniformly warm or thaw samples, such as reagents or frozen biological specimens, to a specific temperature.
Incubating and culturing samples: Water baths can be used to incubate samples at a controlled temperature for a specified period. This is commonly used in microbiology and molecular biology applications, such as growing bacterial cultures, conducting enzyme assays, and hybridisation.
Heating and maintaining consistent temperature for reactions: Water baths can be used for heating and maintaining a constant temperature for chemical and biochemical reactions, such as PCR amplification, DNA melting, and protein denaturation.
Melting point determination: Water baths can be used for determining the melting point of solid samples, such as organic compounds.
- What are different types of water bath?
Some of the water baths that Thermoline Scientific supplies include:
General-purpose uncircuated water baths: These are basic water baths that are suitable for a variety of laboratory applications, including warming samples and incubating cultures.
Circulating water baths: These water baths have a built-in pump or external TU3 heater circulator that circulates the water to maintain a constant temperature throughout the bath. They are commonly used in applications that require precise temperature control, such as PCR amplification and protein denaturation.
Shaking water baths: These water baths have a shaking platform that allows for agitation of samples during incubation. They are commonly used in applications that require mixing, such as bacterial culture growth and hybridisation.
- Should I use an uncirculated laboratory water bath or a circulated laboratory water bath?
The choice between using an uncirculated laboratory water bath or a circulated laboratory water bath depends on the specific requirements of your experiment or application.
An uncirculated water bath can be suitable for certain applications, such as when you need to maintain a consistent temperature in a sample or material that is not sensitive to temperature variations or if your sample is prone to be 'knocked over' by water currents due to its weight and shape. However, a circulated water bath is preferred for most laboratory applications because it provides more consistent and uniform heating.
A circulated water bath typically has a built-in pump that circulates water throughout the bath, ensuring a more even temperature distribution.
