Modular and operator-friendly
The compact design of the BUCHI largescale rotary evaporators combines maximum operator-friendliness with uncompromising security. The parallel glass assemblies are effortlessly assembled and dis-assembled using the EasyClamp connection technique.
The innovative Snap Flange Coupling ensures unbelievably simple and safe attachment and removal of the largevolume flask. The sealing parts, which are compatible with the smaller Rotavapor ® R-220 SE simplify the procurement of spare parts.
Broader temperature range of 20 °C-180 °C (in the Ex-range up to 150 °C)
The electrical heating bath provides an optimal conical shape that enables rapid and energy-saving heating. The bath can be used with oil or water. The integrated bath guarantees with overflow replenishment a constant level. Corrosion is not a factor due to the high-quality stainless steel design and simple cleaning procedure.
Self-explanatory operation
The clear, functional product front makes operation simple and clear. The flask rotation is regulated by a frequency converter between 5 and 100 rpm.
Compact inlet valve
The inlet valve can be opened and closed with one movement of the hand. A metal spring provides for definitive applied force and prevents glass breakage. Fine dosing is provided by means of an adjusting screw.
Flask outlet suction (optional)
The contents of the evaporating flask can be easily sucked out with a PTFE hose. The hose tip is positioned at the deepest point with a magnet. This guarantees complete emptying.
Easy assembling
The evaporating flask is quickly and easily assembled with the innovative snap flange coupling and subsequently fixed securely by a turn wrench.
