Embodiment Construction

[0014] The method for making the smooth, flat and soft thin layer provided by the present invention will be described in detail below in conjunction with specific examples.

[0015] The manufacture method of smooth flat soft thin layer provided by the invention comprises the following steps carried out in order:

[0016] 1) First, heat the mixture of agar or gelatin and water, and fully stir it to form a preparation solution with uniform tissue properties. If necessary, add scattering or absorption media such as simulants and ink dilutions to make the preparation The optical properties of the liquid meet the requirements;

[0017] 2) Spread the heat-resistant film on a smooth and flat glass surface placed horizontally at a temperature of 40-60°C to ensure that there are no air bubbles between the heat-resistant film and the glass; the glass can be placed on a heater with hot water inside Above, the thermal effect generated by the steam in the heater is used to keep the temper...

Abstract

The invention provides a preparation method for a smooth flat soft thin layer. The method comprises the following steps: heating mixed liquor of agar or gelatin and water and carrying out full stirring so as to form a prepared solution; evenly spreading a heatproof thin film on the surface of horizontally-arranged smooth flat glass with a temperature of 40 to 60 DEG C; disposing a bounding frame onto the surface of the heatproof thin film; slowly dumping the prepared solution into the interior of the bounding frame; cooling the prepared solution so as to form a soft thin layer; taking the bounding frame down, separating the heatproof thin film and the soft thin layer from the glass and tearing down the heatproof thin film adhering to the soft thin layer; etc. The preparation method for the smooth flat soft thin layer in the invention has the advantages of simple steps, a reasonable design and convenient operation; the prepared product is smooth and flat, capable of guaranteeing experimental effects.

Description

technical field [0001] The invention belongs to the technical field of preparation of biological experiment materials, in particular to a method for making a smooth, flat and soft thin layer. Background technique [0002] In teaching and scientific research, it is usually necessary to use a soft thin layer made of agar or gelatin to simulate the interaction between light and biological tissue. There are the following problems in the commonly used soft thin layer manufacturing method at present: 1, the equipment is complicated; 2, the flatness of the soft thin layer is poor, that is, the thickness is uneven, so it is easy to break when used, thereby affecting the experimental effect. Contents of the invention [0003] In order to solve the above-mentioned problems, the object of the present invention is to provide a method for making a smooth, flat and soft thin layer with simple equipment and good product flatness. [0004] In order to achieve the above object, the prepar...
