For many years, rotary evaporators (rotovaps) have been a standard in laboratories and industries that perform chemistry, such as laboratories in the pharmaceutical, chemical, life science, materials, environmental and cannabis sectors.

The main applications are solvent recycling, extractions, sample concentration and isolation of solvent mixtures.

Rotovaps consist of a heating fluid bath, rotating motor, evaporating flask, condenser, collection flask, and the vacuum source. Conventional rotovap condensers require external sources of cooling materials such as dry ice, liquid nitrogen, water or glycol. Glycol requires additional recirculating chiller equipment, which is often bulky, heavy, and inefficient, which often restricts their extensive use.

For decades, the conventional rotovaps have also been characterized by unreliability, associated operational costs, inefficient vapor trapping, exposure to carbon dioxide gas from dry ice and dangerous solvent mixtures, health implications of frostbite and environmentally unfriendly.

Using a proprietary and innovative self-cooling technology, Ecodyst has revolutionized the rotovap to be more efficient, to have a smaller footprint, to have greater output, and to be less costly to operate as compared with traditional methods. This disruptive technology has set new standards worldwide for rotary evaporators.

The proprietary modern intelligent self-cooling technology from Ecodyst boosts productivity and prevents downtime. Its refrigerated cooling condenser offers a paradigm shift and sets a new benchmark for cooling down specimens without the use of standard coolants, like glycol, dry ice, or water, thus preventing the significant sources of material waste linked to conventional rotovaps.

The multipurpose hydrogen from Ecodyst is reliable, sustainable, energy-efficient and eco-friendly. This contemporary rotovap also delivers excellent performance, has a smaller footprint, features a huge cooling survey area, is more economical to operate and decreases evaporation time, which enables researchers to pay attention to more difficult tasks.
