Automatic Rotary Evaporator EZL-RE31

Automatic Rotary Evaporator EZL-RE31 features a color digital display for monitoring and controlling rotation speed/temperature, as well as a motorized lift with a 150 mm elevating stroke length. It operates at 200 rpm and allows for vertical lifting for precise positioning of glassware by allowing the use of either water or oil. The unique 1 L bath design heats up quickly, allowing for faster experiments. Bath can reach temperatures of up to 99°C and is designed to be user-friendly while maintaining the highest level of safety.

It is an indispensable instrument for evaporation, concentration, crystallization, separation and solvent recovery in research and production of medicine, chemical and biological products etc.

The Bench-top Series boasts a 3-4 kg per 24 hour condensing rate. For water based samples, -55°C condenser is the perfect choice. For samples containing solvents or with low eutectic points, -80°C condenser provides maximum performance. Designed for maximum flexibility and performance, Benchtop Freeze dryers can be customized with a range of accessories to support the needs of Laboratories and Research/Product Development teams.

With the introduction of the pilot freeze dryers, we have established the connecting factor between a typical bench-top freeze dryer used in laboratories and the industrial large scale freeze dryers.

The TLFD is the largest freeze dryer with all the features and advantages of our smaller freeze dryers, but on a production scale, enabling large scale, controllable freeze drying of bulk samples in a single cycle. Featuring the very latest technology in operator control, the TLFD series has user friendly interface which allows freeze drying 'recipes' to be pre-programmed and stored, giving the end user both flexibility and confidence in the control and monitoring of the entire freeze drying process.
