3 Description of instrument
The Laborota 4000 / 4001 efficient, 4010 / 4011 digital, 4002 / 4003 control
rotary evaporators are designed for distillation and evaporation of solutions.

The solution to be evaporated is in the evaporating flask (2). The solution is
evaporated by applying a suitable temperature of the heating bath (3) and
vacuum pressure as appropriate to the thermodynamic properties of the
solution. The settings can be adjusted on the control panel (5) of the
instrument base (4) and the heating bath controls (3). The drive (1) rotates the
evaporating flask to reduce the danger of boiling delays and accelerate
evaporation by increasing the surface area of the solution. The vapour passes
through the vapour tube into the condenser (7), where it condenses and flows
into the receiving flask (6).
