Description
technical field [0001] The invention belongs to the technical field of bioengineering, and more specifically relates to a high-precision, corrosion-resistant automatic liquid mixing and changing device. Background technique [0002] In the field of bioengineering technology, microscopic imaging is a basic method for observing biological tissues. However, after the biological tissue leaves the living body, the structure and tissue morphology of the cells will be corrupted, so that the original structure and shape cannot be truly reflected under the microscope. Therefore, before microscopic imaging of biological tissue, it is necessary to use a series of chemical reagents to soak it separately, so as to maintain the original structure and shape of biological tissue. In addition, in some imaging instruments that require slicing, for example, when imaging with an electron microscope or a micro-optical tomography system, it is also necessary to embed the sample in resin, so that...
