Overview
LABTOP MSC-2005W + Magnetic Stirring High and Low Temperature Reaction Bath is a Benchtop device using two-stage Compressor cascade refrigeration technology, which can achieve a wide range of temperature control from -20 ° C to 100 ° C. Its core feature is that it combines strong magnetic stirring and precise temperature control. The stirrer in the tank drives the stirrer in the reaction vessel to synchronize swirl/spin to ensure that the temperature of the sample is maintained for a long time and the accuracy is good. The equipment is equipped with an adjustable diameter telescopic cover, which effectively reduces the evaporation and heat exchange of the frozen liquid, provides a stable and reliable low temperature environment for the experiment, and solves the problem that traditional Cooling modes such as dry ice are difficult to maintain stable low temperature for a long time.
Features
1. Adopt two-stage Compressor cascade refrigeration technology, strong refrigeration and rapid cooling.
2. Built-in strong magnetic stirring system can form vortices in the tank to ensure uniform temperature of the sample, especially suitable for low temperature viscosity testing.
3. Equipped with adjustable diameter expansion cover, suitable for reaction vessels of different sizes to reduce refrigerant volatilization and heat exchange.
4. Highlight LED display and waterproof keyboard design, easy to operate.
5. With a variety of power-off recovery modes, the experiment can be automatically resumed after an incoming call to ensure the continuity of the experiment.
6. Support external circulation function (with "+" model) to provide circulation chill down for external devices.
7. Adopt Pt100 temperature sensor, support single point, two point and multi point temperature calibrating, high accuracy.
Optional intelligent control function (RS485/RS232 interface) for remote communication and control.
9. Equipped with sound and light alarm function, and the volume of the buzzer is adjustable.
10. The temperature setting is automatically saved, and the device serial number can be queried through the software.
Principle
The device is based on a two-stage Compressor cascade refrigeration system to achieve strong refrigeration and quickly reach and maintain the set low temperature. The core of its work is magnetic coupling stirring technology: the built-in strong magnetic stirrer swirl/spin in the bath, and the stirrer placed in the reaction vessel is synchronized swirl/spin by magnetic drive, so that the sample in the container is fully and evenly stirred. At the same time, the precise intelligent PID temperature Control system with Pt100 Sensor monitors and adjusts the bath temperature in real time. The adjustable telescopic cover effectively seals, reducing the loss of cooling capacity and medium volatilization in the low temperature environment, and jointly ensures that the experimental process maintains a stable and uniform temperature for a long time.

Steps
1. Place the device on a smooth desktop or ventilated cabinet and connect the power supply.
2. Add an appropriate amount of heat transfer medium (freezing liquid) to the bath.
3. According to the size of the reaction vessel, adjust the opening of the telescopic lid.
4. Place the reaction vessel with the magnetic stirrer in the bath.
5. Set the required temperature, stirring speed and other parameters through the waterproof keyboard.
6. Select the power-off recovery mode (Mode 1, 2, or 3) as required.
7. Start the equipment, start cooling/heating and stirring.
8. During the experiment, the real-time temperature can be monitored through the LED display.
9. After the experiment, turn off the power of the equipment and remove the reaction vessel.
Notice
* Ambient Temperature of the equipment should be between 5 ° C and 32 ° C, and the relative humidity should not exceed 80%.
Make sure the equipment is placed smoothly and leave enough room for heat dissipation.
Before use, please confirm that the medium liquid level in the bath is appropriate to avoid dry burning or reduced cooling efficiency.
According to the experimental requirements, choose the power failure recovery mode reasonably to ensure the safety and continuity of the experiment.
* When performing external circulation operations, please ensure that the pipeline connection is correct and unobstructed.
* Regularly clean the equipment surface and bath to keep the ventilated port open.
If the equipment is alarmed, please check and troubleshoot in time according to the sound and light prompts.
Non-professional personnel should not disassemble or repair the equipment without authorization.
