The R-3 is an entry level rotary evaporator. It fulfills all the basic needs of the customer, specifically targeting the educational market. The quality of the instrument’s mechanical and glass components have not been sacrificed to compensate for the new lower cost. Buchi stands behind its quality. All glassware is manufactured from Schott 3.3 borosilicate glass. The instrument is equipped with standard Buchi features like a one-piece vapor duct, long lasting KD 22 vacuum gasket, and a Combi-clip. This instrument is an addition, not a replacement to, the existing Buchi rotary evaporator portfolio offering a high quality but basic solution for customers requiring only the essentials.
