S700A Rotary Paraffin Microtome

S700A rotary microtome is a fully automatic paraffin slicer, an auxiliary machine that is widely used in medical and biological research to slice tissues after embedding them in wax.





  • Precise injection: 1. The top-level cross guide rail and precision screw rod, combined with the five-phase high-resolution sampling motor and the horizontal sampling slider made of aviation aluminum, form a high-precision sampling system to ensure the quality of slices. 2. Precision motor and encoder ensure stable and smooth automatic slicing.
  • Precision tool holder: 1 . Precise sideways movement function of tool post. After the same sample is moved laterally to replace the knife edge, the position changes very little, and the sample can be cut within 5 knives.2. There are scales on the base of the knife holder, which is convenient for the positioning of the knife holder.
  • Rapid positioning: 1. Patented visual pointer mark, the angle adjustment data is intuitively visible. When adjusting the tissue angles of different inclined planes, the direction of the sample head can be accurately controlled to avoid wastage of tissue samples. 2. Quickly adjust multiple devices to the same angle to keep the same sample at the same angle when sliced by different devices, reducing sample waste caused by rough trimming.
  • Information tracking: 5-inch smart touch screen, background setting adjustment, relevant data, and information display at a glance; with a history recording system (including operation logs and alarm logs), it is convenient for information backtracking and quick problem-solving.
  • Locking system and safety design: 1. It is also equipped with a double-locking system of handwheel lock and arbitrary position lock with its own prompt sound, which significantly reduces the risk of hand injury during the sample block replacement operation, allowing you to change samples with peace of mind. 2. The knife guard covers the entire length of the blade to avoid potential risks of injury during operation. 3. When replacing the blade, the blade ejector can easily push out the blade and remove it safely.
  • Smart slicing: 1. No need to spend time practicing slicing techniques, the machine automatically cuts out high-quality slices. 2. Automatic slicing is stable and can maintain slicing consistency. Fully sectioned specimens such as embryos, brains, etc. require a large amount of sectioning and a heavy task. Using automatic sectioning can relieve your sectioning pressure. 3. Four automatic slicing modes to meet the needs of different slicing scenarios. The window-cutting function ensures the quality of slicing while improving the efficiency of automatic slicing.
