Eco-friendly rotary evaporation is possible and here is .

If you are somewhat skeptical about the eco-friendly claims on lab equipment, well I am on your team. But it would be very nice if the rotary evaporator, as one of the most heavily used instruments in the chemistry lab, was actually "green". Here, I review and experiment with several eco-friendly features of a modern rotary evaporator.

Introduction

ECH 4224L Unit Operations Lab I Thin Film Evaporator 1-2 Theory The following theory assumes that the TFE is operated at a steady-state. In practice it may take a long time for the system to reach a steady-state. Therefore, it will be necessary to monitor the flow rates and concentrations of the top and bottom products as a function of time
