WebMay 5, 2024 · Place rubber hoses on a condenser (wet the ends first to allow them to slide on), then attach the condenser vertically to the round bottomed flask. If using a tall condenser, clamp the condenser to the ring stand or latticework (Figure 1.60a). Be sure the condenser fits snugly into the flask. WebAn evaporator or direct expansion (DX) coil works on the “refrigeration effect”. Cooling occurs when a fluid under pressure and at a temperature above its normal boiling point, has the pressure reduced. This makes the fluid want to boil or “flash” to a gas. For it to boil (“flash”), the liquid must absorb heat from its surrounding ...
