Different Types or Models of Rotary Evaporators
There are several types of rotary evaporators available on the market, each designed for specific needs. Among the most common types are:
-
Benchtop rotary evaporators: These are ideal for laboratories with limited space. These devices offer the same advanced temperature and vacuum control features as larger models but in a more compact format.
-
Industrial rotary evaporators: These models are designed for large-scale processing, where it is necessary to evaporate large volumes of solvent. Industrial rotary evaporators usually have more powerful vacuum systems and larger capacities.
-
Automated rotary evaporators: These models can automatically adjust operating parameters based on the sample’s characteristics, making them an excellent option for high-demand labs with little time for manual adjustments.
Kalstein rotary evaporators are available in various configurations to meet the needs of both small laboratories and industrial facilities. Additionally, the variety of accessories and possible customizations allows for the optimization of the equipment for any application.
Technical Support for Rotary Evaporators
One of the aspects I value most about Kalstein is the attention they provide to their customers through specialized technical support. When we purchased a rotary evaporator for our laboratory, we received comprehensive guidance on its installation and operation. Kalstein’s technical support team not only offers initial training but is also available to answer questions and provide maintenance when needed.
This level of personalized attention not only ensures that the equipment operates correctly but also allows users to maximize all the advanced functions of the device. If you are looking for a supplier that truly cares about the success of your laboratory, Kalstein is an excellent choice.
Compare Prices and Technical Tables of Rotary Evaporators with Similar Products
When I compare Kalstein’s rotary evaporators with other brands like Buchi and IKA, I realize that Kalstein offers the perfect balance between quality and price. While Buchi, for instance, is renowned for the premium quality of its rotary evaporators, their equipment tends to be significantly more expensive, which may not be justifiable for laboratories with limited budgets. On the other hand, IKA offers good quality models but often lacks some advanced features that Kalstein’s rotary evaporators include, such as precise vacuum control and greater customization options.
