Concentration & Evaporation
Choose equipment for solvent removal, extract concentration and sample preparation. Compare rotary evaporation in a rotating flask with parallel concentration of smaller samples, and configure the cooling and vacuum equipment around your process.
Rotary evaporation
A rotating flask and heated bath transfer heat to the sample. Reduced pressure allows evaporation at a lower temperature, while a cooled condenser recovers the solvent.
ROVA901: automatic lift, 5–300 rpm rotation, water/oil bath up to 210 °C and a vertical condenser with 1600 cm² cooling surface.
Sample concentration
Concentrate multiple small samples according to the vessel format, sample count, solvent and method. The SACO range includes sample concentrators for parallel preparation; nitrogen blowdown and vacuum concentration have different operating principles.
Cooling, vacuum and vapour protection
Condenser chiller
A recirculating chiller supplies temperature-controlled coolant to the condenser and removes heat from solvent vapour. The optional CIBAC45 provides a 7.3 L bath and a −10 to +100 °C operating range.
Select cooling capacity at the required setpoint against the solvent load and evaporation rate.
Vacuum pump and control
The pump establishes reduced pressure. A controller regulates the vacuum for a stable process. The optional VACUU-COT30 is an oil-free, single PTFE-head diaphragm pump with nominal pumping speed of 30 L/min.
Cold trap
A cold trap captures residual vapour in the vacuum line when additional vapour protection is needed. It has a separate role from the circulating chiller that cools the evaporator condenser.
Match the trapping temperature and capacity to the solvent, operating pressure and vacuum pump.
Information for model selection
Include the solvent, starting sample volume, target concentration, sample count per day, temperature sensitivity and required processing time. For a complete system, specify glassware, cooling, vacuum pump, regulation and vapour protection.
