 waiting for chillers –   Rotovap and pump are in stock 
The USA Lab 50L EXRDS Series rotary evaporator turnkey system recovers solvents efficiently and fast with two times the surface area for condensing and twice the recovery volumeOur EXRDS series evaporator is an explosion proof evaporator with brush-less motors and enclosed internals to prevent any flammable / explosive material from touching the internals via seals. 
This unit provides consistent and repeatable results at an affordable price. With dual condensers and dual receiving flasks made of GG-17 High Borosilicate Glass, all pieces have been designed for efficient use of surface area, higher capacity’s and higher recovery rates. This means faster recovery without compromising quality. Our evaporators come standard with safety features such as over-temperature shut off and dry-run protection. All valves and ports are high efficiency allowing a continuous feed of material as well as draining the receiving flask without breaking vacuum. 
This turnkey system comes equipped with two of our 50L DLSB-50/30 -30°C chillers, providing low temperatures and high flow rates for each condensing set-up. This allows for higher recovery rates than a single condenser set-up or using one chiller on two condensers. Our turnkey set-up also comes equipped with one of the highest quality diaphragm pumps made by Vacuubrand. The MD 4C NT 2.2CFM pump is rated for 15,000 hours maintenance free and provides a superior vacuum with an oil-free, corrosion resistant system.
No expense has been spared with these evaporators, yet we crush the market on pricing to provide great value at a low cost. Our evaporators are the best value on the market and each one comes with fantastic customer servicelocal product support and a 1 year warranty.

Three-stage chemistry-design diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors and meet even challenging requirements. The three-stage design provides the advantageous combination of high pumping speed and very low ultimate vacuum. All parts of the MD 4C NT in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE sandwich diaphragms provide increased reliability and extended operating life. Due to the gas ballast valve and its very good ultimate vacuum (even with gas ballast) the MD 4C NT is also suitable for pumping condensable vapors of high-boiling solvents. The NT-series features further improved performance data, easy service and superior vapor tolerance.

Performance features

  • outstanding chemical resistance and superior vapor tolerance
  • exceptionally high performance even at low vacuum
  • excellent ultimate vacuum even with gas ballast
  • whisper quiet and very low vibration
  • long diaphragm life, maintenance-free drive system
