BÜCHI Rotavapor® R-300
Versatile rotary evaporation platform for laboratory solvent removal, sample concentration, distillation, drying and reflux applications.
The Rotavapor R-300 can be used as a stand-alone rotary evaporator or configured as an integrated evaporation system with BÜCHI vacuum, cooling and control components. Its modular design allows the system to be selected around the laboratory's solvent, flask size, temperature, condenser, documentation and automation requirements.
- Modular rotary evaporation platform for routine solvent removal, concentration, distillation and drying.
- Available as a stand-alone unit or as part of a fully integrated evaporation system.
- Integration with BÜCHI vacuum pumps, recirculating chillers and system controllers.
- Centralized control of rotation, heating, vacuum and cooling when configured as an integrated system.
- Suitable for pharmaceutical, chemical, food, academic, research and industrial laboratories.
- Flexible configuration of condenser, flask size and accessories according to the required application.
Supplied and supported in Pakistan by Continental Worldwide Trading Company (CWTC).
Key Features
Modular system architecture
The user can begin with the required system scope and add control, cooling, sensing or automation according to the workflow.
Flask capacity up to 5 L
Suitable for laboratories processing larger sample or solvent volumes.
Heating up to 220 °C
Extends the system beyond routine water-bath evaporation into applications requiring higher bath temperatures.
Wide condenser selection
The system can be selected according to solvent properties and workflow rather than forcing every application into one glass configuration.
Centralized system control
Improves consistency, operator convenience and control of routine distillation workflows.
Sensor and automation options
Helps reduce manual intervention and improves control of more demanding evaporation processes.
Where the Rotavapor R-300 fits in laboratory workflows

Reaction Work-Up & Solvent Removal
Supports reaction work-up, solvent removal, concentration, recrystallization and reflux processes with flexible glassware, temperature control and operating options.

Concentration of Extracts
Provides controlled reduction of solvent volume after sample extraction and before instrumental analysis, supporting repeatable sample-preparation workflows.

Extract Concentration & Solvent Recovery
Concentrates extracts, removes solvents and recovers volatile components with configurable temperature, condenser and system control for different applications.

Discuss accessories →Frequently Asked Question
The R-300 can support evaporating flasks up to 5 L when configured with the B-305 heating bath. Smaller flask sizes can also be used according to the selected glassware and application.
Yes. The B-305 heating bath supports water or oil and can operate up to 220 °C. The selected temperature and heating medium must be suitable for the application and laboratory safety requirements.
No. The R-300 is modular. A stand-alone configuration can be used without full system automation. Integrated control, dynamic distillation, sensor compatibility and programmable methods depend on the selected interface and supporting system components.
Both interfaces support centralized control, solvent-library functions, dynamic distillation and compatible sensors. The I-300 Pro additionally supports programmable methods, guided operation and a larger display.
The condenser depends on the solvent, boiling point, available cooling source, laboratory height, reflux requirement and whether the sample is prone to foaming or bumping. CWTC should review the application before confirming the glass assembly.
The R-80 is intended for compact routine evaporation with flasks up to 1 L. The R-180 supports routine evaporation with flasks up to 3 L. The R-300 supports flasks up to 5 L, higher-temperature operation and a wider range of automation, condenser and sensor options.
Yes. CWTC can provide system-selection support, installation, operator training and after-sales technical support according to the supplied configuration and service scope.
