The S-EVAP-KD solvent evaporator combines standard Kundera-Danish concentration procedures with a unique rotary water bath and manifold, increasing sample throughput and conserving bench space. The instrument comes in 5, 8, and 10 position models. The S-EVAP-KD instruments are available in two temperature control options: digital control or mechanical thermostat. Different models accommodate various flask sizes (250 mL, 500 mL, and 1000 mL). Organization's S-EVAP solvent evaporators have a broad range of applications including concentrating extracted materials from Solet operations and other KD evaporation methods. At each sample position, the KD flask rests on the bath cover disk and the concentrator tube sits partially submerged in the deep water bath below the cover disk. The solvent boils from the flask and through the Snyder column. The solvent vapor then cools in the condenser which is attached to a centrally located water manifold. The glassware is held in place with quick disconnect fittings which allow for easy retrieval of samples. The solvent leaves the condenser through a specially designed side arm into either an individual collection flask or a centrally located solvent collection vessel. Solvent recovery through individual or central collection options reduces laboratory emissions and increases laboratory and environmental safety.
