Description
Technical Field
The application relates to a vacuum negative pressure agarose gel forming easy demoulding mould.
Background
Agarose gel is a jelly-like hydrogel which is formed by dissolving agarose powder in water and then coagulating. It can be used for extracting DNA, biological culture and simulation of biological tissue, etc. For the simulation of biological tissues, the agarose concentration and other chemical reagents are changed to change the mechanical properties of the biological tissues and make the mechanical properties of the biological tissues and human organs close to those of the biological tissues so as to simulate the influence of various variables on the biological tissues, and the agarose gel is generally called a phantom.
Although the young's modulus of the agarose gel is close to that of human qi organs or other biological tissues, the tensile strength and the compressive strength of the agarose gel are much different, and the tensile strength and the compressive strength of the agarose gel are much lower than those of the biological tissues, so that the prepared agarose gel is very fragile and is sugar in nature, the surface of the agarose gel still has viscosity, and the agarose gel is often broken in the demolding process. And is difficult to move onto the experimental platform even if the mold is completely removed.
Agarose gels are also often subjected to high temperatures during the preparation process, which can cause the gas to dissolve into the gel solution, causing bubbles to form in the final gel, which can affect experimental results and observations.
