The combination of the detachable 8.7" capacitive touchscreen and additional navigation and emergency stop hard keys allow for maximum usability and remote control.
Various factors influence the distillation rate of a Rotavapor®. The following tips help you to improve the efficiency of your distillation process, to conserve energy and to reduce the environmental impact. The following charts show the distillation rate of acetone as a function of temperature, rotation speed and flask size, respectively.
Heating bath temperature:
A high heating performance (i.e. > 3.6 kW) only affects the distillation rate at high heating bath temperatures. For a difference of 20 °C or less between the vapor and bath temperature, distillation rates of a R-220 Pro, R-220 Pro High Performance or R-250 are identical.
To make use of the high heating power of a R-220 Pro High Performance or a R-250, set the bath temperature as high as possible
High rotation speed produces maximum turbulence inside the flask resulting in higher evaporation rates. However, for highly viscos samples, some foaming products, or spillage of heating media (e.g. when a drying flask is used), high rotation speed is not applicable.
Recommendation: The higher the rotation speed, the faster the distillation.
The larger the surface of the sample inside the flask, the higher the evaporation performance. On the other hand, large flasks are more difficult to handle and the sample is distributed over a larger area when evaporating to dryness.
Recommendation: The sample volume ideally fills 1/3 to ½ of the flask size.
Despite the wide range of glass assemblies and accessories, customer-specific needs often require customization of standard items such as:
BUCHI’s vast experience and profound knowledge make us the ideal and competent partner in advising customers.
We develop and produce our instruments ourselves, which allows us to modify certain instruments or even manufacture a special part according specific customers need.
By concentrating your product the main focus is on speed to ensure the product is not exposed to heat
for a long time.
Common situations during the concentration process:
The main focus to recycle or purify solvents is to get the distillate as clean as possible. With a high recovery rate.
BUCHI’s Industrial Rotavapor® features various safety measures:
AutoDest – Distill automatically without supervision
The AutoDest sensor combined with the Interface I-300 Pro enables unattended automatic distillation by automatic vacuum adjustment according to the required cooling capacity of the condenser. Solvent emissions into the laboratory atmosphere are thus minimal as condenser overload is avoided.
Sensors and valves – Define your degree of automation
Different automation levels are possible depending on the accessories chosen:
