FAQs
How is cryogenic shredding carried out?
Cryogenic shredding can be carried out in the PTFE beaker, which is pre-cooled in liquid nitrogen. This enables the processing of temperature-sensitive materials without thermal damage.
Which materials can be shredded with the PULVERISETTE 23?
The grinder can grind a wide range of materials, including biological samples, chemical substances and various materials used in materials science. The choice of grinding tools (zirconium oxide, stainless steel, hardened steel, PTFE) allows customization to specific requirements.
How is the final fineness of 5 µm achieved?
The final fineness of 5 µm is achieved through a combination of high oscillation frequency (900 - 3,000 oscillations/min) and the selection of suitable grinding balls (0.1 - 15 mm diameter). The grinding time can be adjusted depending on the material in order to achieve optimum results.
Conclusion
The FRITSCH PULVERISETTE 23 Mini Mill is a versatile and powerful laboratory mill characterized by its precision, ease of use and energy efficiency. It is ideal for a wide range of applications in materials research, chemistry, biology and pharmacy and offers an excellent solution for grinding small sample quantities.
