FAQs  

1. Q: How do I set up the temperature and rotation speed?

A: Use the LCD touchscreen to input desired values. The PID system auto-stabilizes the temperature, while the rotary knob adjusts RPM (0-120). Refer to the rotary evaporator manual for calibration guidelines.

2. Q: Is the RE-2002 compatible with corrosive solvents?

A: Yes. Its borosilicate glass and PTFE seals resist acids, bases, and organic solvents. Avoid prolonged exposure to hydrofluoric acid or strong alkalis.

3. Q: What safety features prevent overheating?

A: The machine has auto-shutdown upon exceeding preset temperatures, leak-proof vapor pathways, and an emergency stop button for immediate intervention.

4. Q: How do I clean the glass components?

A: Disassemble gently and rinse with distilled water or mild solvents. Never use abrasive tools. The rotary evaporator manual includes a detailed cleaning protocol.

5. Q: Can it handle heat-sensitive samples like essential oils?

A: Absolutely. Precise low-temperature control (down to ambient) and adjustable RPM ensure gentle evaporation without degrading delicate compounds.
