Rotary Evaporator with Precise Speed Regulation for Chemical & Pharma Labs

Both B and E series models feature precise rotational speed display; our LRE-3000E (E type) integrates an LCD screen for clear, real-time speed monitoring.

Intelligent digital temperature control is powered by a PT100 sensor, which automatically cuts off heater power once the set bath temperature is reached, and resumes heating when temperatures drop below the set point, maintaining consistent water bath temperatures between room temperature and 99℃.

The rotation system comprises a stable, high-reliability micro motor, speed-regulating motor, and integrated circuit control unit. Enabled by electronic speed regulation, it maintains steady rotation within the 10-180 RPM range, meeting advanced domestic and international performance standards.

The vertical lifting system utilizes a motor-driven rotary structure for smooth, controlled height adjustment of the evaporation unit.

Two optional condenser configurations are available for organic solvent evaporation: one based on dual-line convection principles, and a single-line design compatible with water, ice, or dry ice-filled interlayers. The vertical condenser design minimizes bench space usage.

The rotation shaft is constructed from high-temperature-resistant borosilicate glass, offering excellent heat tolerance and sealing capabilities. Sealing components employ a PTFE + PTFE bidirectional seal for superior leak resistance.

A dedicated heating bath with an integrated resistance wire heater provides uniform heating, supporting a temperature range from room temperature to 99℃ to suit various experimental needs.
