Overview
LABTOP MSC-4005W + Magnetic Stirring High and Low Temperature Reaction Bath is a Benchtop equipment using two-stage Compressor cascade refrigeration technology. Temperature range can reach -40 ℃ to 100 ℃. It forms a vortex in the tank through a built-in strong magnetic stirrer to achieve long-term stability and uniformity of the sample temperature, especially suitable for low temperature viscosity testing. The equipment is equipped with an adjustable diameter telescopic cover, which effectively reduces the evaporation and heat exchange of the refrigerant, provides a stable low temperature environment, and solves the problem that refrigerants such as dry ice cannot maintain low temperature for a long time.
Features
1, using two-stage Compressor cascade refrigeration technology, strong refrigeration, quickly reach the set temperature.
2. Built-in strong magnetic stirring system ensures that the mixing in the tank and the reaction vessel is synchronized, with good temperature uniformity, especially suitable for low-temperature viscosity testing.
3. Equipped with adjustable diameter expansion cover to adapt to different sizes of reaction vessels, reducing refrigerant volatilization and heat exchange.
4. Waterproof keyboard design, high-brightness LED display, intuitive operation.
5, small size, suitable for desktop and ventilated cabinet use.
6. Equipped with sound and light alarm function, the volume of the buzzer is adjustable.
7. Temperature settings are automatically saved, and multiple power-off recovery modes are supported to ensure the continuity of the experiment.
8, using Pt100 temperature sensor, support single point, two point and multi point temperature calibrating.
9. It can be connected to an external loop (with "+" model) to provide a chill down solution for external equipment.
10. Optional intelligent control function (RS485/RS232 interface), supporting remote communication and control.
11. The device serial number can be queried through the software.
Principle
The device realizes strong refrigeration based on a two-stage Compressor cascade refrigeration system, chilling down the medium (frozen liquid) in the bath to a set low temperature. At the same time, the built-in strong magnetic drive drives the magnetic stirrer in the tank to swirl/spin at high speed to form a uniform vortex flow field in the bath, and synchronously drives the stirrer swirl/spin placed in the reaction vessel through magnetic coupling, so as to achieve uniform stirring and temperature control of the reaction material. The adjustable telescopic cover seals most of the bath openings, effectively isolates the environment and maintains the temperature stability in the tank.
Applications
Chemical Synthesis, Materials Science, Biopharmaceuticals, Petrochemicals, Viscosity Testing, Low Temperature Reaction Research
Standards
The data did not mention specific compliance criteria.
Steps
1. Place the device in a smooth desktop or ventilated cabinet and connect the power supply.
2. Add an appropriate amount of freezer to the bath.
3. Place the reaction vessel into the bath and adjust the size of the expansion cover according to the diameter of the vessel.
4. Put a magnetic stirrer in the reaction vessel.
5. Set the required temperature and stirring speed parameters through the waterproof keyboard.
6. Start the equipment, and the refrigeration and mixing systems start working.
7. During the operation of the equipment, the LED screen displays temperature and other information in real time, and the experiment can be started after the set conditions are met.
8. After the experiment, turn off the power supply of the equipment and remove the experimental container.
9. If external circulation is required, connect the corresponding pipeline and start the external circulation function.
Notice
* Permissible Ambient Temperature of the equipment is 5~ 32 ℃, relative humidity ≤ 80%, please ensure that it is used in a suitable environment.
Equipment allows 100% continuous operation, but it is necessary to ensure good heat dissipation.
* Please confirm that the amount of freezer in the bath is sufficient before use, and check the replenishment regularly.
When adjusting the expansion cover, be careful to avoid pinching or damaging the container.
* Please set the appropriate power failure recovery mode through the menu before booting according to the experimental requirements.
* When remote control or calibrating, make sure the cable is correct and reliable.
Be sure to disconnect the power supply before cleaning the equipment to avoid liquid entering the electrical part.
If there is an alarm, please check and troubleshoot in time according to the sound and light prompts.
