Büchi^® rotary evaporator Model R-205

Modular construction makes it possible to configure units from two evaporator models, R-200/205, two vacuum controller models, V-800/V-805, and three different glassware assemblies, all supplied with a standard 24/40 joint on the evaporator flask and a 35/20 ball joint on the receiving flask.

Model R-200 Evaporators:

• 33% smaller footprint than previous models
• Chemically-resistant PTFE/glass vacuum-sealing system lasts up to five years
• Space-saving modular design lets you add integrated vacuum controllers and run preset time/pressure gradients
• Motorized, quick-action servo-jack raises and lowers glassware effortlessly
• Wide-range, PTFE-coated 4L heating bath, model B-490, with digital temperature display, uses oil or water, 20 to 180°C (68 to 356°F)
• Enhanced safety: insulated heating bath, Plastic+Glass-coated glassware, and optional remote control and safety shield
• Process samples from 50 mL to 3 L

Model R-205 Evaporators:

• Same as R-200, plus digital vapor temperature display

·
Evaporator with diagonal condenser assembly
For simple distillation of solvents and general use. Tap-water-cooled. Inlet feed tube for continuous feed of volumes exceeding flask capacity.
Evaporator with cold-trap condenser assembly
Two-piece cold-trap condenser style is ideal for low-boiling solvents. Uses mechanical refrigeration or dry ice and acetone.
Evaporator with vertical condenser assembly
For distilling high-boiling solvents (>100°C). Tap-water-cooled. Inlet feed tube for continuous feed of volumes exceeding flask capacity.
