The granulator Pulverisette 14 from Fritsch is a laboratory device that has been specially developed for the fast and precise comminution of soft to medium-hard samples. With a maximum rotor speed of 24,000 revolutions per minute and a peripheral speed of up to 120.8 metres per second, the mill enables efficient comminution of ductile or plastic materials. For temperature-sensitive materials, the grinder offers the option of working with external coolants such as liquid nitrogen or dry ice. Particularly challenging materials such as synthetic resins, films and plastics can also be ground efficiently after pre-treatment with liquid nitrogen.
Through a combination of impact and shearing forces, the regrind is fed through a sieve into a collecting device, resulting in a defined final fineness. The final fineness that can be achieved depends on the material properties and the grinding tools used. Special rotors and sieves made of titanium as well as PTFE-coated collecting vessels are available for iron-free grinding. A wide range of accessories is available for special applications, including various rotors, sieve rings and cyclone separators. The high-performance cyclone separator enables improved cooling and a higher final fineness, which further expands the mill's range of applications. The grinder is operated via an intuitive touchscreen, which allows the speed, grinding time and other parameters to be set.
The granulator is equipped with comprehensive safety functions, including overheating protection that automatically switches off the appliance if the temperature exceeds 80 degrees Celsius. The lid of the grinder is locked during operation and can only be opened when it is not in use, ensuring safe handling.
The granulator Pulverisette 14 combines flexibility, safety and efficiency when shredding a wide variety of materials. With its robust design and wide range of applications, it is ideal for use in laboratories and universities.
