The working principle of the microtome is relatively simple, that is, the sharp section of the microtome is applied, and the object and the data are cut into pieces according to the ratio or width of one point. For use in consumer, pharmaceutical or other uses.
Different slicer slices are also used in different ways. For example, cells or tissues should be disposed of, so that the experiment can be stopped with a microscope. Rotary and slide-away microtome for optical microscopy also requires a microtome in the paper industry, such as a knife-type slicer, a drum slicer, a spiral slicer, and the like. The cutter-type slicer consists of a cutter head, a casing, a feeding trough, and a transmission installation. The working principle is to apply a heavy cutter head to the flywheel to stabilize the slicing.
Another is to cut the polymer strip into pellets. This requires a special microtome consisting of a guide bar, a feed roller, a pressure roller, and a rotary cutter. The working principle is that the application cutter disc is driven by the continuously variable transmission, and the feed roller is driven by the cutter disc through a set of conversion gears, and the cutter disc is equipped with a plurality of blades according to the pellet size. The ability to interchange the shifting gears allows for changes in the cut-off length and the speed at which the continuously variable transmission can change the strip.
The characteristics of the slicer can be divided into the following points:
1. The compact, independent control panel effectively controls all important operations.
2. The built-in control panel and the independent control panel are completely synchronized. The LCD screen can indicate the total thickness of the slice and the total slice, the thickness of the trim, the thickness of the slice, and the important operation status.
3. Two sample vertical stop positions (upper and lower)
4, five slice modes: single, continuous, step, half knife, programming
5. The slicing speed is automatically adjusted according to the slice thickness.
6, the trim function can be turned off. In the automatic state, the parameters of the trimming block are automatically adjusted. In the manual state, the parameters of the trimming block can be programmed.
7. Slice thickness and trim thickness can be independently selected and stored.
8. The visible signal and the sound signal indicate the limit of forward and backward and the remaining injection distance when injecting.
Optional cold light source, magnifying glass or stereoscope to meet the needs of semi-thin sections, optional ultra-low temperature liquid nitrogen refrigeration system for semi-thin sections of special samples.
