Introduction To Refrigerated And Heated Circulating Water Baths
Refrigerated and heated circulating water baths is a new type of test equipment, with a strong magnetic stirring at the bottom, and a secondary stirring and circulation system to make the temperature in the tank more uniform. source. Cold sources that require high-precision temperature supply, such as biomedicine and experimental research. It is widely used in the test and identification of biological enzymes in hospital scientific research.
Refrigerated And Heated Circulating Water Baths Features:
It can be used in the range of low temperature (-80C) to high temperature (99C).
The temperature control adopts PID method, which has high control precision.
The temperature setting and display adopt digital mode, which is easy to operate and easy to monitor.
The diameter of the tank cover can be adjusted to effectively reduce the loss of refrigerant during operation.
Equipped with a fixed frame for external parts, it is convenient to install burettes, external sensors, etc.
Can be used from low temperature (-80°C) to high temperature (99c).

Refrigerated And Heated Circulating Water Baths application：
The low temperature and constant temperature reaction bath has a wide range of applications in the fields of chemistry, medicine, biology, and environmental protection.
In chemistry
Refrigerated and heated circulating water baths can be used in the synthesis of catalysts, organic synthesis, coordination chemistry, catalytic reactions, polymerization reactions, etc. in the field of medicine
Refrigerated and heated circulating water baths can be used in drug synthesis, purification, crystal growth, etc. the
In the biological field
Refrigerated and heated circulating water baths can be used in enzyme-catalyzed reactions, protein structure research, DNA/RNA rocking amplification, PCR reactions, etc.
In the field of environmental protection
Refrigerated and heated circulating water baths can be used for water and soil sample processing, environmental pollution analysis, gas and liquid chromatography analysis, etc.
Operation Use:
- The location should be ventilated and there should be no other equipment within 1 meter around the instrument to ensure that the heat generated is dissipated in time; and it should be placed horizontally and stably.
- Open the box cover, pour in the appropriate amount of medium according to the required constant temperature requirements, and connect the inlet and outlet of the circulating fluid equipment with the insulation hose; Whether the connection is good.
- Insert the power plug into an independent socket, turn on the safety switch on the side of the instrument, press the power switch on the control panel, the actual temperature will be displayed, and press the symbol on the control panel to set the temperature.
- Press the refrigeration switch on the panel, the compressor starts to work after a 3-minute delay, and at the same time when the refrigeration is turned on, if internal circulation is required, open the internal circulation valve (not on the control panel, open it manually), and press the button on the control panel “Cycle” switch to ensure uniform bath temperature.
- The stirring device controlled by the stirring switch on the panel is installed at the bottom of the medium, which is used to stir the medium to make the temperature uniform. For 10 and 11, only one can be opened.
- After use, turn off the “circulation” switch on the control panel; the internal circulation valve and the refrigeration switch in turn. The stirring speed is set to 0, and there is a power switch and a safety switch, and the power plug can be pulled out.

FAQ
Q: Refrigerated and heated circulating water baths are not stirred.
A: You should check the agitator line, if there is no problem, please replace the agitator with a new one. Also, when touching the device and feeling electrified, please check the grounding wire. It is relatively rare that the equipment does not cool. If so, please check the compressor and check whether Freon is leaking. Please solve it in turn.
Q:refrigerated and heated circulating water baths do not operate according to the settings.
A: First check whether the power supply of the device is connected prope rly. If there is no problem, check whether the heating fuse or cooling fuse is normal (check the steps, first turn off the power of the machine, unplug the power cord, and then open the insurance cover to see if the fuse is blown. Whether the connection is normal, after the inspection is normal, close the insurance cover, plug in the power cord, and turn on the device switch)
Q: The cooling speed of refrigerated and heated circulating water baths has dropped sharply and the noise is getting louder.
A: If these two problems occur, please turn off the power and check the windshield of the cooling vent, wipe off the dust and debris on it with a dry cloth, open the cooling vent, and use a brush to remove the dust and debris on the fan.
Q: The connecting pipe of refrigerated and heated circulating water baths leaks air and water.
A: You should first check whether it is formed by the condensation of water vapor in the air. If so, ignore it, just wipe it off, and reduce the humidity of the environment. If it is not the moisture in the air, please turn off the device, carefully check the leak, unscrew the connection, wipe it clean, seal it with high-strength glue, connect it again, and turn it on for inspection.
