• Medium size rotary evaporators
• Comes standard with a 10L sample flask
♦ Equipped with the NVC-3000 vacuum controller, which provides four control modes and comprehensive monitoring of operating conditions for enhanced ease of use.
♦ The 20L water/oil heating bath supports a wide temperature range (RT +10°C to 180°C), enabling concentration of high-boiling-point substances.
♦ The upgraded drive motor, now with inverter control, provides more powerful operation and supports rotation speeds up to 140rpm.
♦ A safety cover prevents accidental contact with rotating components. A float switch in the bath protects against dry heating by detecting low liquid levels.
♦ By connecting the N-3100 to the diaphragm vacuum pump N950 (both sold separately) using the dedicated N-SB cable, the pump can be automatically controlled based on the evaporator’s operating status.
• Improved operability and safety features
♦ LCD screen
◊ The enlarged LCD screen offers improved readability. The layouts for vacuum, rotation speed, and temperature control have been redesigned for better usability.
Vacuum controller screen
Temperature, rotation speed screen
♦ Safety cover
The safety cover is standard to prevent accidental entanglement of hands or clothing during rotation.
♦ Float switch
The system detects low water levels and issues an alert before the bath runs dry.
♦ Teflon® seal
The Teflon® vacuum seal enables high vacuum performance (below 2.6hPa). It offers a longer service life than Viton seals, reducing replacement frequency and overall operating costs.
♦ Auto jack and sample flask
The one-touch clamp and sample flask support allow for quick and secure flask attachment/removal. The motorized auto jack ensures smooth and stable bath height adjustment.
♦ USB port for data transfer
Parameters including bath temperature, rotation speed, vacuum, and vapor temperature can be retrieved via the micro USB port.
Download the dedicated software for data logging and analysis.
♦ Dedicated stand
The unit comes with a dedicated stand, which makes it easy to move and operate, and can store the vacuum pump and consumables. It also has an earthquake-resistant structure that can be fixed to the floor with anchor bolts.
