P-23
Ultra-compact mini mill for ultra-fine grinding of very small sample quantities
The ultra-compact FRITSCHP-23 Vibrating Mill was specifically designed for the fine grinding of very small quantities of medium-hard, brittle, and moist samples—whether wet, dry, or cryogenic. With a footprint of just 20 × 30 cm and a weight of 7 kg, the unit can be easily placed anywhere in the lab and delivers outstanding results at an attractive price-performance ratio.
Unmatched grinding efficiency thanks to spherical grinding jars
The P-23’s unique selling point is its specially developed spherical grinding jars. Unlike comparable mills with cylindrical grinding jars, the spherical inner shape ensures significantly better grinding performance during grinding, mixing, and homogenization. Grinding occurs through impact and friction between the grinding balls and the inner wall of the grinding jar, with the optimally designed interior achieving significantly higher efficiency. In addition, the spherical geometry makes it considerably easier to recover the sample and simplifies cleaning.
Convenient quick-release system for efficient operation
The spherical grinding jars snap together easily and quickly without the need for screws—a practical quick-release system enables batch-by-batch processing in the laboratory. The grinding jar is set in vertical oscillating motion 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 a precisely adjustable grinding time.
Versatile Applications
Grinding jars in various volumes are available for different applications. The small-volume grinding jar is suitable for very small sample volumes of 0.1–5 mL, while the larger grinding jar is ideal for sample preparation for asbestos analysis. PTFE jars in 5- and 30-ml sizes are available specifically for biotechnology applications, in which, for example, fungal or yeast cells or frozen tissue samples and cells can be disrupted in just a few minutes. The entire jar can be pre-cooled in liquid nitrogen for this purpose.
A special container for single-use tubes is available for the efficient homogenization of even the smallest sample volumes—particularly in the biological field. The container can hold up to six 0.5-ml, 1.5-ml, or 2-ml PCR tubes. Samples that are typically in liquid form can be lysed very quickly and gently in the individual tubes using 1-mm grinding beads.
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, as well as for handling toxic or hazardous substances. This includes work in an isolator involving biohazardous, radioactive, or pharmacologically active substances. The P-23 Control software enables seamless installation and firmware updates via a USB-C connection for operation inside a glovebox.
A Variety of Materials for Optimal Results
To prevent unwanted contamination from abrasion, three different material types are available for grinding jars and grinding beads, including zirconia for completely metal-free grinding. The small contact surface area with the grinding tools further minimizes abrasion.
With a power supply of 100–240 V/1~, 50–60 Hz, and a power consumption of just 50 watts, the device operates energy-efficiently. The control panel, featuring an integrated, easy-to-clean glass keypad, makes operation, cleaning, and maintenance particularly simple—ideal for daily laboratory use in chemistry, environmental research, pharmaceuticals, biotechnology, and materials synthesis.
