HM 325 Rotary Microtome: Performance and Precision in the Laboratory
The HM 325 from Thermo Fisher Scientific is a rotary microtome designed to meet the demands of biological, medical, and industrial research laboratories. It ensures optimal section quality while providing user comfort and enhanced safety. Its ergonomic design and features make it a top choice for professionals needing a reliable and precise solution.
The precision micrometry system of the HM 325 allows for fine adjustment of section thickness, ranging from 0.5 µm to 60 µm. The cutting control can be operated with either the left or right hand, thanks to removable buttons on both sides of the device. A display window at the front shows the selected thickness in real-time, ensuring optimal control during sectioning.
One of the major strengths of this microtome is its backlash-free vertical movement mechanism. This system ensures maximum sample stability and reduces vibrations, even during cuts requiring significant force. The automatic retraction of the sample during the return of the sample holder improves section quality and facilitates the creation of paraffin section ribbons. This feature also extends blade life.
The blade holder system of the HM 325 is designed to offer optimal stability while ensuring ease of use. The reduced number of levers prevents confusion during handling and ensures quick and secure blade attachment. The ergonomic design of the blade holder allows for use by both right- and left-handed individuals, and the integrated finger guard provides additional protection against accidental injuries.
The microtome is also equipped with a flywheel braking system, allowing the device to be locked in any position. This feature ensures safe sample exchange and simplified handling. Fine sample orientation, with a quick-lock function, facilitates precise alignment along the horizontal (X) and vertical (Y) axes, minimizing the risk of artifacts during sectioning.
Another distinctive feature of the HM 325 is its section collection tray. Designed to cover the entire cutting area, it prevents waste accumulation under the blade holder and facilitates cleaning. Its front part is specially designed to serve as an armrest, ensuring more comfortable use even during prolonged work.
With its smooth and precise manual cutting mechanism, the HM 325 is ideal for applications in histology, cytology, and pathological anatomy. It offers an optimal balance between compactness, performance, and ease of use. Its robust construction ensures increased longevity and minimal maintenance, making this device a sound investment for laboratories seeking a reliable and efficient microtome.
