Low temperature constant temperature reaction bath

working principle

Low temperature constant temperature reaction bathOn the basis of the low-temperature coolant circulation pump, the heating tube heating constant temperature function is added. The required temperature is set through the instrument. When the refrigerant is about to cool to the required temperature, the heating tube automatically starts and works simultaneously with the compressor to keep the refrigerant temperature constant at the required temperature; The magnetic stirring function has also been added, which allows the reaction vessel to be directly placed in the bath for magnetic stirring. This device can directly cool the reaction vessel for constant temperature reaction and magnetic stirring, and can also circulate the refrigerant to other devices for cooling; You can also choose this device to heat the material (up to 50 degrees Celsius when using ethanol for high temperature; not lower than 0 degrees Celsius when using water, up to 99 degrees Celsius for high temperature). The fully enclosed magnetic stirrer ensures mixing stability.

It can be equipped with a built-in secondary stirrer, which, together with the stirrer inside the reaction vessel, maintains a uniform temperature of the sample.

Adjustable slot cover diameter reduces refrigerant consumption.

Equipped with a fixed rod for easy placement and fixation of burettes, sensors, and other supporting devices.

Internationally renowned brand compressors with high reliability and efficiency.

Installation Instructions

1) The device is placed on a horizontal plane.

2) If the machine is inverted during transportation, it should be left for 24 hours before being turned on for debugging.

3) All ventilation openings of the machine itself must not be covered! There should be at least 70 centimeters of open space around the equipment, and sufficient ventilation should be provided to ensure that the temperature around the equipment does not exceed 40 ° C.

4) When delivering cold sources to the outside world, if the horizontal position of the cooled equipment is higher than the horizontal position of this equipment, the inlet valve should be immediately closed or the refrigerant should be discharged after use to prevent the refrigerant from flowing back and overflowing.

5) If any dangerous goods such as liquids splash onto the machine, they should be wiped off first. After confirming that the machine is not damaged, it can be started and operated.

Precautions and maintenance techniques

1. Pay attention to the range of temperature and humidity.

2. After injecting liquid into the liquid tank, it is strictly prohibited to handle the instrument at will or tilt it to avoid danger or damage caused by the intrusion of working medium into the components.

3Low temperature constant temperature reaction bathThere should be sufficient space and good dust prevention around the areas with heat dissipation holes. Keep the instrument away from heating equipment and avoid direct sunlight.

4. The instrument should not be used in places that are flammable, explosive, or have severe environmental corrosion.

DFY series low-temperature constant temperature water bath working power supply: 220V/50Hz, the power supply power should be greater than the total power of the instrument, and the power supply must have a good "grounding" device;

Add liquid medium into the low-temperature constant temperature bath before use. The liquid level of the medium should be about 30mm lower than the worktable, otherwise the heater will be damaged when powered on;

When the operating temperature is higher than room temperature, please turn off the cooling, and the reaction bath can be kept at a constant temperature.

Please do not use ethanol when the temperature is above 30 ° C to avoid danger (due to the fast evaporation rate at high temperatures, it is prone to danger)

It should be placed in a dry and ventilated place, with no obstacles within 300mm around the instrument;

When the working temperature of the constant temperature bath is high, be careful not to open the cover and do not enter the bath with your hands to prevent burns; After use, place all switches in the off state and cut off the power supply;

Do a good job of cleaning and keep the workbench and operation panel clean.
