The Rotavapor RII fullfills exactly the fundamental needs of classical laboratory applications in teaching and research, practically and dependably, without compromising quality or safety. Available in three different glassware assemblies, all supplied with a standard 24/40 joint (US) or 29/32 (Europe) on the evaporator flask and a 35/20 ball joint on the receiving flask, and a choice of either standard glass or plastic-coated glass.
Model R II features:
Continuous vapor duct and a PTFE composite vacuum seal for long service life and effective sealing
Small footprint and robust design in powder-coated aluminum
Manual quick-action jack
Heating bath for temperatures of 0 to 95°C, quick-release electrical connection for easy removal
Process samples from 50 mL to 4 L
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 vertical condenser assembly For standard distillations and for high-boiling solvents (>100°C). 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.
