1. Working power supply: AC220V ± 10% 50Hz;

2. Water bath temperature: room temperature~100 ℃± 1 ℃

3. Cold bath temperature: -35 ℃± 0.1 ℃;

4. Evaporation temperature: 35 ℃± 1 ℃;

5. Glass rotor flowmeter: (0-10) L/min;

6. Timer timing range: (0-60) min.

7. Cone weighing bottle capacity: 15mL~25mL

8. Cooling time: ≤ 100min

1. The cold bath is an independently designed refrigeration device (imported compressor refrigeration) with a total of 4 cold tanks, which can simultaneously test 4 samples.

2. The cold bath and evaporator device are separated to avoid affecting the accuracy of the test during the operation of the refrigeration device.

3. The evaporator at 35 ℃ is an air bath evaporation device, with a controlled temperature of 35 ℃. The blowing volume entering the sample in the evaporation device is detected by a glass rotor flowmeter, which can accurately control the blowing volume according to the specific requirements of the test. The blowing time can be set arbitrarily by a timer within 60 minutes according to the time requirements of the test.
