Rotary Evaporator RN Series

Product Overview

The RN Series Rotary Evaporators employ stepless speed regulation to maintain a consistent rotation of glass flasks, forming uniform material thin films on their inner walls. Coupled with an intelligent constant-temperature water bath for even heating, the system enables rapid solvent evaporation under vacuum. Vapors are efficiently condensed in a glass condenser and collected. Designed for vacuum applications, all wetted parts are made of heat-resistant borosilicate glass and PTFE, making these evaporators ideal for concentrating and purifying heat-sensitive biological samples.
Features
  • Fuse safety protection with automatic power-off for dry-burn prevention (Excludes Basic Series).
  • The water bath pot features an aluminum alloy + Teflon composite coating with fully enclosed heating.
  • The main frame is constructed from high-quality aluminum alloy for optimal structural integrity
  • Electronic stepless speed regulation (5–310 rpm) with digital RPM display for easy operation.
  • Vertical double-layer serpentine coil condenser ensures high recovery rates, with an additional feeding tube.
  • Valve-type feed tube with PTFE tubing connection enables seamless continuous feeding.
  • All glass components are made of high-borosilicate glass (GG-17) for high temperature and corrosion resistance.
  • Sealing system employs a dual combination of PTFE and imported fluoroelastomer to maintain high vacuum levels.
  • Digital display and intelligent temperature control for the water bath, with a PT100 sensor for rapid and accurate temperature transmission.
  • Manual weight-balanced lifting for the main unit, combining sliding lift and manual adjustment.
    • Model-Specific Features :(LCA-RN-1300B / LCA-RN-1300BE - Manual & Electric Lift Models)
  • LED screen for intuitive digital RPM display.
  • Brushless DC motor for high efficiency and long service life
  • Programmable forward/reverse rotation with timing function for optimized sample mixing.
  • Bi-directional condenser mounting (left/right adjustable) to accommodate diverse laboratory setups and user preference.
  • Reinforced glass shaft supports a 3L rotary flask, suitable for large-volume sample concentration.
  • Arc-shaped base design allows 360° placement of the main unit around the water bath, maximizing space utilization
  • Electric lifting for the main unit (only LCA-RN-1300BE) for safe and convenient operation.
