The KNF RC 900 rotary evaporator is ideal for efficient evaporation processes in laboratory environments. Its modern design and sophisticated construction ensure precise control of the entire rotation and heating process. In particular, its safety features and intuitive operating concept set it apart from many standard systems on the market, making it a preferred solution for laboratories in research, development and production.

Performance features and ease of use

This device combines reliable performance with user-centred operation. Professionals benefit from the following advantages:

- Motor lift with removable remote control: Facilitates handling and adjustment of rotation or heating parameters. - Wireless heating bath: Prevents tripping hazards and can be used flexibly under a wide range of working conditions. - Wide speed range (25 to 250 rpm): Easily adapts to different protocols, from gentle rotation to higher speeds.
- Large cooling surface of 1230 cm²: Effectively lowers vapour density, reduces energy consumption and speeds up process times.
- Stroke of 150 mm: Provides sufficient scope for individual adjustment of the evaporation position. - Automatic lifting of the piston in the event of a power failure: Protects samples and users and ensures safe shutdown. - DGUV V3 and VDE-compliant components: Support a high level of occupational safety and reliability.

In addition, the device is virtually silent, which has a positive effect on the working atmosphere. Even during prolonged continuous use, the temperature control remains stable and the overheating protection ensures a constant level of safety.

Fundamental to this rotary evaporator is the combination of its slim design and high adaptability to different test conditions. This applies both to flexible placement within the laboratory and to integration into various exhaust air or vacuum systems. Weighing only 9.1 kg, the device can be easily moved without compromising operational safety. Technical aspects at a glance In addition to the aforementioned range of functions, other specifications play an important role in everyday laboratory work. The heating bath is adjustable from 20 °C to 180 °C and, with its heating power of 1300 W, provides sufficient reserves for fast heating phases. The permissible pressure of the cooling circuit is 3 bar, with an accepted temperature range for cooling media from -15 °C to +20 °C. With a flask volume of 50 ml to 3000 ml, this evaporator covers a wide range of sample and product volumes. Instead of complicated cabling, the wireless power supply of the heating bath minimises the risk of errors and tripping. The entire assembly is IP 20 protected, which guarantees sufficient safety for typical laboratory situations.

Application examples

In daily practice, the RC 900 rotary evaporator performs a wide variety of tasks:

- Removal of volatile solvents such as ethanol, methanol or acetone from sample liquids. - Concentration of sensitive substances, for example to reduce analytical detection limits.- Drying heat-sensitive materials, such as pharmaceutical active ingredients. - Fractional distillation for separating mixtures of substances in research laboratories. Thanks to its variable configuration, the device can be used in chemical, pharmaceutical and biotechnology laboratories, as well as in areas that require process development or quality control.

FAQs

How often should maintenance be carried out?

A technical inspection in accordance with DGUV V3 and VDE should be carried out at least every one to two years to ensure long-term safety and performance.

Which flask sizes are suitable?

The rotary evaporator supports flasks from 50 ml to 3000 ml, so the range for different applications is wide.

What happens in the event of a power failure?

In the event of a sudden power failure, the flask is automatically lifted out of the heating bath. This protects the device and prevents damage to the sample.

Can the temperature be controlled precisely?

Thanks to the motorised lifting mechanism and finely tuned heating control, precise temperature control in a range from 20 °C to 180 °C is easily possible.

Conclusion

With its combination of high operational reliability and flexible range of applications, this rotary evaporator is considered a reliable solution for demanding laboratory processes. Its quiet operation, automatic motor lift, wireless heating bath and sophisticated safety mechanisms are particularly impressive. If you are looking for a powerful, safety-oriented and easy-to-use evaporation system, you will find the right equipment here for a wide range of routine and special applications.
