• The only 20L Rotary evaporator with stainless steel housing. Quality that last forever
• Patented flask clamp Snap action mechanism: Quick, easy and safe way to fix the evaporating flask
• Patented EasyClamp connections: Secures glass joints quickly, easily and safely
• The large evaporating flask with its weight burnt-in. The weight is marked in grams. Precise weight +/- 1g
• Feed valve: Quick or continuous addition of sample without breaking vacuum
• Seven different glass assemblies for every application the right configuration
• “Plastic+Glas” coating on all glass components with the exception of evaporating flasks. This coating offers maximum protection for personnel against implosions and glass breakage without hindering operation
• The integrated vacuum controller on the R-220 SE regulates and optimizes the distillation process with special features such as Timer, Gradient, Repeat … Timer function stops rotation, bath temperature and lift position after a programmed time is achieved
• Spring-loaded shut-off valves prevent glass breakage as a result of excessive force during closing
• Graduated receiving flasks for measurable reproducible results, PTFE base outlet valve for chemical resistant easy emptying
• Universal heating bath for use with water or oil up to 180°C
• Large display for clear indication of important data such as: Actual bath temperature, Vapor temperature, Coolant temperature, Cooling status ON/OFF, Rotation speed …
• A safety shield made of PMMA protects the entire glass assembly, but is unrestricted visibility of the process. Rotation stops when shield is open
• An adjustable upper temperature limit prevents unintentionally change of the setpoint. An overtemperature sensor switches the Rotavapor off when setpoint temperature has been exceeded by 15°C

Optional accessories for time and cost savings

• Foam detector: The internal PTFE foam sensor detects and breaks down rising foam with a short aeration pulse. Therefore, you can use the foam sensor to eliminate the time consuming monitoring process of extract reduction
• Level sensors: Receiving flask level sensor terminates operation when predetermined waste levels are achieved. Particularly helpful for concentration of product.
• Data storage: Easy data storage on USB stick. Saves parameters from application runs (temperatures, pressure, rotational speed) on a USB stick for data transfer
