P-23
Ultra-compact mini mill for ultra-fine grinding of the smallest sample quantities
The ultra-compact FRITSCH Mini-Mill P-23 was specially developed for the fine comminution of very small quantities of medium-hard, brittle and moist samples - wet, dry or cryogenic. With a footprint of only 20 × 30 cm and a weight of 7 kg, the instrument can be easily positioned anywhere in the laboratory and impresses with excellent results at an attractive price-performance ratio.
Unrivaled effective grinding effect thanks to spherical grinding bowls
The unique selling point of the P-23 is the specially developed spherical grinding bowls. Unlike comparable grinders with cylindrical grinding bowls, the spherical inner shape ensures a significantly better grinding effect when grinding, mixing and homogenizing. Comminution is achieved by impact and friction between the grinding balls and the inner wall of the grinding bowl, whereby the optimally adapted interior achieves a significantly better degree of efficiency. In addition, the spherical geometry enables considerably easier recovery of the sample and simpler cleaning.
Practical quick-clamping system for efficient work
The spherical grinding bowls can be easily and quickly fitted together without screwing - a practical quick-clamping system allows you to work in batches in the laboratory. The grinding bowl is set to oscillate vertically at 900-3,000 oscillations per minute with an amplitude of 9 mm. The controlled oscillation frequency (15-50 Hz) ensures fast, reproducible grinding with precisely adjustable grinding time.
Versatile applications
Grinding bowls in different volumes are available for various applications. The small grinding bowl volume is suitable for the smallest sample quantities of 0.1-5 ml, while the larger grinding bowl is perfect for sample preparation for asbestos analysis. PTFE beakers in 5 and 30 ml are available especially for biotechnological applications, in which fungal or yeast cells or frozen tissue samples and cells, for example, can be digested in just a few minutes. The complete beaker can be pre-cooled in liquid nitrogen.
New glovebox-ready option
The P-23 Glovebox Ready is the ideal solution for precise grinding in a controlled atmosphere. It is suitable for chemical syntheses or reactions in an oxygen- and moisture-free atmosphere and for handling toxic or hazardous substances. This includes working in an isolator when handling biohazardous, radioactive or pharmacologically active substances. The P-23 Control software enables seamless installation and firmware updates via USB-C connection for operation in a glovebox.
Variety of materials for optimal results
To avoid unwanted contamination from abrasion, three different types of material are available for grinding bowls and grinding balls, including zirconium oxide for absolutely metal-free grinding. The small contact surface with grinding tools further minimizes abrasion.
With a connection of 100-240 V/1~, 50-60 Hz and a power consumption of just 50 watts, the appliance is energy-efficient. The control panel with integrated, easy-to-clean glass keypad enables particularly simple operation, cleaning and maintenance - ideal for daily laboratory use in chemistry, environmental research, pharmacy, biotechnology and materials synthesis.
