Heidolph 20L Rotary Evaporator VC5000 Chiller, 3 ph

Shopping for a Rotary Evaporator? Here’s what to watch out for.

Cascade partners with Heidolph because there are key differences between Heidolph and less expensive rotary evaporators.

Rotary evaporators are systems made up of key components (glass surface area, vacuum pump, vacuum control, chiller) that can make or break overall system performance and rates of evaporation and recovery.

All rotary evaporators are not created equal. Many resellers or low-cost importers will include under-performing chillers, loose or non-existent vacuum control, thin glass and lesser vacuum pumps that may lower the initial price tag, but end up costing the customer plenty in on-going maintenance, inefficient evaporation times and lost man hours tuning the systems.

Vacuum control is a key component for efficient rotary evaporation. Vacuum control allows for “walk away” distillation, rather than having a person dedicated to controlling vacuum. When vacuum levels are manually controlled but not consistently monitored, the vacuum pump can be quickly destroyed and solvent recovery is much less efficient.

Rotary evaporators also have motors that spin the flasks. Less expensive motors can run hot and overheat.  When this happens, processing must stop until the motor cools down. Thin, unbalanced glass can easily break, contributing to consumables costs.

The Heidolph Difference

Heidolph offers a best in class, 3 year warranty and on-site expert installation and training.  Expect this investment to have a performance life of 10-15 years and low cost of ownership.

Protect Expensive Product. A temperature sensor powers off the bath in case of any uncontrolled heat-up event.

Work Smarter, More Effectively. Minimize Supervision Time.
The unique integrated evaporating flask support system allows for “one person operation” to remove the flask in just moments.

The automatic water bath refill system along with an additional control panel for filling and electronics allow for use over an extended period of time and eliminates with worry of running dry.

The secondary 10L recovery flask allows drainage without breaking vacuum.  This is a tremendous time savings in the process of rotary evaporation.

Want continuous, unattended evaporation 24/7?

Heidolph Safety Features

• All condenser and receiving flasks are protected by transparent, high impact PMMA doors.
• A non-fogging guard hood protects the bath completely, but still allows for visible monitoring.
• A temperature sensor powers off the bath in case of any uncontrolled heat-up event.
