• Medium Size Rotary Evaporator
• A 20L sample flask is provided as standard
• Space-saving design suitable for laboratory use
N-4100 Standard model N-4100W with two receiving flasks
♦ N-4100 has a footprint of 1060W x 550D (mm) and comes equipped with a 20L sample flask as standard. A 10L sample flask (optional) is available for smaller sample volumes.
♦ 40L heating bath with a wide temperature range (RT+10℃ to 180℃). Water/oil bath allows for the concentration of high-boiling point substances.
♦ The vacuum controller has pre-registered programs for 55 types of solvents, including those specified by environmental standards. Solvent recovery can be efficiently performed by selecting the solvent and appropriately controlling the vacuum.
♦By connecting the N-4100 to the diaphragm vacuum pump N950 (sold separately) using the included power cord, you can control the pump according to the operating conditions of the N-4100.
• Improved operability and safety features
♦ LCD screen
◊ The vacuum controller has been redesigned and the screen is now 4.3 inches, making it even easier to read.
◊ RPM and temperature values are now also displayed digitally on the LCD.
♦ USB port for data transfer
Parameters such as bath temperature, flask rotation speed, vacuum level, and vapor temperature can be retrieved via the micro USB port.
The dedicated software is available for download on our website.
♦ Safety cover
A safety cover is standard equipment to prevent hands or clothing from getting caught during rotation.
♦ 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.
♦ Designed for improved ease of use, with an easy-to-attach and detach sample flask
The combination of the flask base and the one-touch clamp allows for easy attachment and detachment of the sample flask. The bath height is conveniently set at 800mm for better operability. Changing to the optional 10L sample flask can also be done easily.
♦ Double receiving flasks (N-4100W)
By equipping two receiving flasks, it is possible to discharge the distillate from the receiving flasks without stopping the equipment during concentration. Since the vacuum conditions remain stable, continuous concentration can be performed in a stable state.
♦ Dedicated stand
The unit comes with a dedicated stand, making handling and operation easier, and provides storage for the vacuum pump and consumables. It also has an earthquake-resistant structure that can be fixed to the floor with anchor bolts. N-4100H is available for those who do not need a stand.

◊ The ultimate vacuum is based on the use of an oil-sealed rotary vacuum pump.
◊ Evaporation capacity varies depending on conditions such as the degree of vacuum, bath temperature, and cooling water temperature.
◊ The temperature control range depends on the ambient temperature and evaporation rate.
◊ Power plug is not included.
