Very easy Handling without the Loss of Grinding Media 

The grinding chamber of the LabStar laboratory machine can be swiveled. In the „Prepare“ position, different grinding systems can be coupled with the machine platform quickly and easily. The grinding media are simply filled from above into the process chamber. In the operating position, we guarantee a homogeneous distribution of grinding media in the grinding container. At the right angle of inclination, the service position allows the uncomplicated and residue-free discharge of the agitator bead mill. Screw connections allow quick disassembly of all components for cleaning.

Grinding Systems 

The LabStar leaves nothing to be desired in terms of application possibilities. All of the familiar grinding systems can be mounted on the LabStar.

Zeta® System
Zeta® System

The Zeta® circulation system, patented in 1991, was specially developed for recirculation grinding. The Zeta® grinding system is available in various materials
such as NETZSCH-Ceram Z, NETZSCH-Ceram N or NETZSCH-Ceram C or NElast. The grinding system is designed such that very flexible grinding media sizes between 0.1 mm and 2.0 mm can be used.

Neos System
Neos System

The Neos grinding system is a horizontal peg grinding system for grinding temperature-sensitive systems with very small grinding media at extremely high product throughput rates in circulation mode. Based on the proven Zeta® grinding system, it was specially designed for reliable use of very small grinding media between 0.1 mm and 0.8 mm.

Discus System
Discus System

The advanced disk grinding system Discus is primarily used for dispersion tasks in single and multi-pass operation with grinding media sizes between 0.3 mm and 2.4 mm. It is a logical advancement of the TriNex® grinding system.

Flexibility without Limits

Flexibility without Limits 

The variation possibilities of the multifunctional laboratory mill - the LabStar - have been extended by another feature. Now you can not only select from the two scale-up-capable grinding systems Discus and Zeta®, as well as a variety of material options, but also convert to the smaller grinding chamber designs of the 230 ml MiniSeries and 110 ml MicroSeries. A special conversion kit has been developed for this purpose, which requires short assembly times. This new additional feature makes the LabStar the most flexible all-round laboratory mill on the market.
