cooling circulator & heater circulator
Laboratory experiments that involve liquid baths often require precise temperature control, making the ability to manage fluid temperatures critical. To achieve accurate and consistent temperature control, laboratory circulators are commonly used. These devices are specifically designed to regulate and maintain the temperature of liquids, which is especially important for experiments that involve dissolution testing.
A laboratory circulator typically includes a liquid reservoir, a heating and/or cooling system, and a temperature control mechanism. Some models work with a separate liquid bath or water jacket, while others combine both functions in one. Temperature ranges can be from –120 °C to 200 C°, with pump flows of up to 70 L per minute. Higher-end models usually have a wider temperature range. Digital temperature control is common, but some circulators use analog technology for cost savings and customization.
Laboratory circulators and chillers are designed to accurately control the temperature of fluids, such as deionized water, bath fluid, or PH-neutral buffer. They are used to deliver the controlled fluid to various laboratory equipment, including water baths, analytical instruments, incubators, and wet processing stations.

FAQ
What is a heated circulator?
A heated circulator is a laboratory equipment used to precisely control the temperature of fluids. It is often used in experiments that require consistent and precise temperature control, such as dissolution testing. The circulator typically features a liquid reservoir, a heating system, and a temperature control mechanism. The temperature range of a heated circulator can be as wide as -95°C to 300°C. It is commonly used in life science research, drug discovery, material testing, wafer production, and wet chemistry.
What is a cooling circulator?
A cooling circulator is a laboratory cooling system that provides consistent and precise temperature control for experiments that require cooling. It features a liquid reservoir, a cooling system, and a temperature control mechanism. These circulators can be used to cool or chill samples, and supply temperature-controlled water to external equipment. They are commonly used in life science research, drug discovery, material testing, wafer production, and wet chemistry. The temperature range of cooling circulators can be as wide as -95°C to 200°C
What is the purpose of a heater circulator?
The purpose of a heater circulator is to provide a consistent and precise temperature control for experiments that require heating internally or externally. These circulators feature a liquid reservoir and a heating system, along with a temperature control mechanism. They are ideal for maintaining a few temperature set points over a long period of time and are commonly used in laboratories for experiments that involve liquid baths. Heating circulators come in open or closed baths and offer a wide temperature range from –90 to 300°C and heat load removal of up to 1000 watts.
What is a circulating water bath?
A circulating water bath is a laboratory equipment that maintains a constant temperature by circulating water. This equipment is designed to enable the rapid heating and cooling of samples by constantly circulating water. It is commonly used in life science research, drug discovery, material testing, wafer production, and wet chemistry. Circulating baths offer efficient temperature maintenance over a wide range of temperatures, ranging from -90 to 300°C, and heat load removal of up to 1000 watts. They are ideal for holding samples such as flasks and beakers, and can also be used to circulate fluid to external equipment in open- or closed-loop applications.
How does a heater circulator work?
A heater circulator works by heating a fluid and then circulating it through the system. The heating element, often an electric coil or a heating mantle, provides controlled heat to the fluid. The pump, typically a magnetic or centrifugal pump, circulates the fluid through tubes or a bath, ensuring even temperature distribution. The fluid absorbs heat from the heating element and transfers it to the desired location, such as a reaction vessel or a temperature-controlled chamber. Temperature sensors and controllers are used to monitor and maintain the desired temperature within a specified range. The combination of heating and circulation allows for precise temperature control and uniform heating throughout the system.
How does a cooling circulator work?
Cooling circulators work by utilizing a refrigeration system to cool the circulating coolant. The coolant is pumped from the reservoir through a cooling coil or heat exchanger, where it absorbs heat from the system being cooled. The heated coolant then flows back to the refrigeration system, which removes the heat and lowers its temperature. The cooled coolant is then circulated back into the system to maintain the desired temperature. The temperature is regulated and controlled by a temperature controller that monitors and adjusts the refrigeration system and pump speed accordingly.
What types of fluids can be used with a heater circulator?
Heater circulators can be used with a variety of fluids depending on the specific application requirements. Commonly used fluids include water, oils, and silicone-based fluids. Water is a popular choice due to its availability, low cost, and good heat transfer properties. Oils, such as mineral oil or silicone oil, are often used when higher temperature ranges or better heat stability are required. Silicone-based fluids are suitable for applications that involve low temperatures or require inertness. It is important to select a fluid that is compatible with the materials of construction in the heater circulator and consider the desired temperature range, heat transfer properties, and safety considerations when choosing the appropriate fluid.
What are the advantages of using a cooling circulator?
Cooling circulators offer several advantages for temperature control and cooling applications. Firstly, they provide precise and stable temperature control within a specific range, ensuring accurate and repeatable experimental results. The ability to maintain constant temperatures is crucial for many laboratory processes, such as chemical reactions, sample storage, and equipment cooling. Secondly, cooling circulators are versatile and can be used with a wide range of laboratory equipment, such as rotary evaporators, reactors, and spectrophotometers. They also come in various sizes and cooling capacities to accommodate different cooling requirements. Additionally, cooling circulators are energy-efficient, as they recycle and reuse the coolant, minimizing water consumption and reducing operating costs. Overall, cooling circulators enable efficient and controlled cooling in laboratory and industrial settings.
Can a heater circulator be used for cooling applications?
Yes, certain models of heater circulators can also be used for cooling applications. These units are often referred to as heating and cooling circulators or temperature control systems. They feature both heating and cooling capabilities, allowing for precise temperature control within a wide range. The cooling function is achieved through a refrigeration system that circulates a coolant, such as water or refrigerant, through the system. This enables the user to cool down a process, vessel, or chamber to the desired temperature. Heating and cooling circulators are commonly used in applications that require rapid temperature changes or control over a broad temperature range, such as thermal cycling, material testing, or biological sample preservation.
What safety precautions should be taken when using a cooling circulator?
When using a cooling circulator, it is important to follow safety precautions to ensure safe operation and prevent accidents. Firstly, proper training should be provided to personnel operating the circulator to ensure they understand its operation, safety features, and emergency procedures. Secondly, it is crucial to regularly inspect and maintain the cooling circulator, including the refrigeration system, pump, and electrical connections, to ensure safe and reliable operation. Any potential leaks or malfunctions should be promptly addressed. Thirdly, appropriate personal protective equipment (PPE) should be worn, such as gloves and safety glasses, when handling the coolant or performing maintenance tasks. Additionally, the cooling circulator should be placed on a stable surface and away from any potential obstructions or flammable materials. Proper grounding and electrical safety measures should also be followed.
