KNF RC 900 - Benefit from Expert Knowledge

Under the spotlight at KNF: What aspects are really key to rotary evaporation in everyday lab practice? What is needed to guarantee simple,
economical and reliable processes day in day out?

These are the questions we used as a guide in developing and implementing the new RC 900. We became involved in daily lab work. We asked
lab technicians what they wished for, enlisted experts to perform tests and incorporated their suggestions.
The result was the RC 900: designed to impress thanks to its distinct handling advantages, clever functional details and well thought out safety

Inspiringly easy to use

Designed for everyday use, and tailored to practical needs. The RC 900 makes rotary evaporation far simpler and safer. Reliability, operational safety and precision come as standard with the RC 900.
