Problems solved by technology

[0004] The prior art adopts the transparent method of the microporous membrane to refer to the formation of a transparent carrier to facilitate observation under a microscope, but the carrier formed in this case cannot directly use the microscopic method of the oil lens, cedar oil will affect the microporous membrane. The added substances make the originally transparent microporous membrane opaque. Therefore, there is currently no good way to use the microporous membrane as a carrier for oil microscope observation

Abstract

The invention discloses a preparation method of microscope lens oil capable of transparentizing a microporous filter membrane. According to a refraction coefficient of a microscope lens, membrane transparent liquid with the refraction coefficient which is the same as or similar with the refraction coefficient of the microscope lens is selected as the lens oil; meanwhile, in a process of detecting components intercepted by the microporous filter membrane, the lens oil is added into the microporous filter membrane, so that the microporous filter membrane has a transparent state; a material of the microporous filter membrane has a transparent material property; the prepared microporous filter membrane is at a non-transparent or semi-transparent state; the error between an refraction index of the lens oil and the refraction index of the material of the microporous filter membrane is no more than + / -10 percent. The invention aims at providing the preparation method of the microscope lens oil capable of transparentizing the microporous filter membrane; one type of liquid is prepared and a non-transparent microporous filter membrane is changed into a completely transparent microporous filter membrane; the liquid is also used as the lens oil in an oil lens observation process and an unprecedented convenient and effective novel method is provided for morphological detection.

Description

technical field [0001] The invention relates to a method for preparing a transparent microporous filter membrane and a liquid used as microscope lens oil in the inspection and detection process using membrane separation technology in the fields of medicine, biology, environmental science, etc., specifically a method that can be transparent and microscopic Preparation method of microscope oil for pore filter membrane. Background technique [0002] As we all know, a microscope is an optical instrument used to observe small objects. Usually, a microscope cannot be used for direct observation, because the microscope must be on a transparent background to observe specific shapes, and glass slides are usually used. When the microscope requires a high magnification, the lens is very small. When the light passes through medium objects of different densities (slide→air→lens), part of the light will be refracted and lost. The light entering the lens barrel is less and the field of vie...
