Join the ZM Challenge & Win!

Sep 13 2022

For almost 50 years, RETSCH ultra centrifugal mills of the ZM series have set standards in fast and reproducible sample homogenization. The latest model, ZM 300, is the fastest rotor mill in the market and perfectly suitable for a wealth of applications.

The maximum speed of classic centrifugal mills is usually limited to 18,000 rpm. The ZM 300 achieves up to 23,000 rpm and produces particles which are 15 to 20 % finer in comparison to conventional rotor mills, depending on the material. The high speed also allows for an increase of sample throughput by 10 to 15%.

The variable speed range allows for optimum adaptation of the grinding process to the sample requirements by keeping the grinding time as short as possible and the temperature increase as moderate as possible. Too much heat may have a negative effect on the grinding results, for example, if moisture or volatile components escape.

The ZM 300 is equipped with an integrated temperature sensor which measures the temperature of the cassette lid near the ring sieve. The measured temperature is constantly shown in the mill’s display, allowing the user to optimize the grinding process and improve reproducibility.

Take part in the ZM Challenge - and win great prizes!

We are looking for the longest-serving ultra-centrifugal mill of the ZM series, but also younger ZM models can participate in the raffle and win a brand-new ZM 300.
