Mini-mill for fine comminution of small sample quantities
In various fields such as pharmaceuticals, environmental research, and biotechnology, there is often a need to finely grind small quantities of samples, ranging from brittle to moist materials. Achieving precise and reproducible grinding results can be challenging with conventional grinding methods.
Grind and homogenize small sample amounts efficiently
The Mini-Mill PULVERISETTE 23 from Fritsch is designed for fine comminution of very small quantities of medium-hard, brittle, and moist samples under dry, wet, or cryogenic conditions. Notably, it uses spherical grinding bowls that enhance its grinding, mixing, and homogenizing performance compared to similar models. The Mini-Mill operates through impact and friction, with grinding bowl oscillations of 900 to 3,000 per minute at an amplitude of 9 mm. This innovative design, combined with a compact footprint of 20 x 30 cm and a weight of 7 kg, makes it suitable for various lab environments. The instrument offers precisely adjustable and reproducible grinding times and features a user-friendly operation panel with an easy-to-clean glass keyboard. For those working in biotechnology, accessory PTFE grinding bowls are available, which are ideal for breaking up cells or pre-cooling in liquid nitrogen.
