Introduction of some main technical operations of thermostatic magnetic stirrer

The constant temperature magnetic stirrer is an ideal analytical instrument for the liquid temperature, stirring, measuring data and analyzing the product in the laboratory, analysis room and laboratory of petroleum, chemical, geological exploration, medical and health, biochemical experiments and other industrial and mining enterprises.

Second, thermostatic magnetic stirrer technical conditions

1, power: AC220V ± 15%

2, mixing capacity: 20-3000cc

3. Working mode: continuous at <70 °C

4, stirring speed: 0-1250 rev / min stepless speed regulation

5, the minimum consumption rate: 20W 7, heating maximum temperature: 100 ° C

6, the maximum consumption rate: 79-3 type 235W  81-3 type  250W

Third, the constant temperature magnetic stirrer structure principle : has the advantages of simple structure, convenient use, low noise, etc., because the magnetic steel is directly driven by the motor shaft, the mechanical failure is less, and the speed regulation is stable. The stirring rotor is fully enclosed by high-quality magnetic steel, and the performance of the PTFE material is extremely superior.

Fourth, the constant temperature magnetic stirrer operation sequence and method

1. Turn on the voltage and turn on the power switch indicator.

2. Turn on the stirring switch indicator and turn the potentiometer from left to right to make the stirring rod in the beaker slow and fast.

3. To heat the temperature control, connect the conductive temperature gauge wire to the D-type plug and insert it into the hole of the rear thermometer. When the temperature rises to the pre-adjusted degree, the heating will stop automatically.
