Removing the condenser☞ Use the ring spanner provided to loosen union nuts that are tightlyfitted.☞ Loosen the union nut by turning anticlockwise.Description of special condensers• RV10.3 Vertical-intensive condenser with manifoldThis vertical-intensive condenser features a double jacket designfor particularly efficient condensation.Also available with coating (RV10.30)• RV10.4 Dry ice condenserDry ice condenser for distilling low-boiling solvents.Cooling by dry ice, no cooling water required. Maximum conden-sation thanks to low temperatures.Also available with coating (RV10.40)Not suitable for use with the RV10 control in automatic mode.• RV10.5 Vertical-condenser with manifold and cut-off valve forreflux distillationAlso available with coating (RV10.50)• RV10.6 Vertical-intensive condenser with manifold and cut-off valve for reflux distillationThis vertical-intensive action condenser features a double jacketdesign for particularly efficient reflux distillation.Also available with coating (RV10.60)Hose system☞ Connect the water hoses to the condenser according to the coun-ter-flow principle (fig. 14).☞ Install the vacuum connections to the condenser, Woulff bottle,vacuum controller with valve and vacuum pump.☞ Always connect the vacuum hose to the condenser at the high-test point to minimise solvent losses during suctioning.☞ Use typical laboratory vacuum hoses with an inside diameter of8 mm and a wall thickness of 5 mm (see accessories).Fig.13Fig.14042009 21
