Benefit from the market leader Frequently asked questions What is the chimney effect and how does it affect distillation efficiency? By evaporation - changing of state from liquid to gas - the volume of the sample increases by a factor up to 20,000. In the condenser the gas is re-condensed to a liquid and the volume shrinks immediately. During this evaporationcondensation process, vapor velocity at narrow points of the glass apparatus can be up to 150 km/h. Are the condensers shown on the page 9 compatible with the older generation of BUCHI Rotavapor® product lines (R-215, R-210, R II, R-3)?...
