• Medium Size Rotary Evaporator
• 10L sample flask as standard
♦Equipped with an NVC-3000 vacuum controller. The controller offers four control modes and comprehensive monitoring of operating conditions, enhancing ease of use.
♦ 20L heating bath with a wide temperature range (RT+10℃ to 180℃). Water/oil bath allows for the concentration of high-boiling point substances.
♦ The drive motor has been upgraded (with inverter control) for more powerful operation, achieving speeds of up to 140rpm.
♦ Equipped with a safety cover to prevent hands or clothing from being caught while rotating. Additionally, a float switch is installed in the bath to prevent dry heating.
♦ By connecting the N-3100 model with the diaphragm-type vacuum pump N950 model (sold separately) using the dedicated N-SB connection cable (sold separately), the pump can be controlled according to the operating status of the evaporator.
• Improved Operability and Safety Features
♦ LCD screen
◊ LCD screen is larger and easier to read. The vacuum, rotation and temperature control screens have been redesigned.
Vacuum controller screen
Temperature, rotation speed screen
♦ Safety cover
A safety cover is standard equipment to prevent hands or clothing from getting caught during rotation.
♦ Float switch
The system detects the lower liquid level and alerts you to a water level drop before running dry.
♦ Teflon® seal
The Teflon® seal allows for high vacuum operation (below 2.6hPa). Compared to Viton seals, it offers a longer lifespan, reducing the frequency of seal replacement and contributing to cost savings.
♦ Auto jack and sample flask
The sample flask support and the one-touch clamp make attachment and removal of the sample flask easy and secure. The bath can be smoothly raised and lowered with a motorized auto jack, ensuring stable movement.
♦ USB port for data transfer
Parameter data such as bath temperature, flask rotation speed, vacuum, and vapor temperature can be retrieved via the micro USB port.
Download the dedicated software.
♦ 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.
