As a leading manufacturer of Rotary Evaporators, Büchi is setting new standards in the kilo laboratory and production scale and now presents the 50 litre flask format. The large rotary evaporators R-250 and R-250 EX are designed for a rapid and low temperature distillation. Exact, reproducible operation with a high degree of operating comfort is possible. The "Scale-up" from laboratory to production plant is particularly easy.
The modular design allows the devices to be fitted according to individual needs in a flexible manner. Imprecise heating with steam or oil is eliminated. In addition, the new Rotavapor® R-250 EX complies with the strict standards 94/9 (ATEX) of the European Union for ex-safety, which is obligatory since 2003. An important aspect to consider for your future, safe investment decision.
