Abstract
Description
Technical Field
[0001] The utility model relates to the field of biotechnology, in particular to a rubber cutting tool with adjustable spacing. Background Art
[0002] Agarose gel electrophoresis is a method for separating nucleic acids in the field of biotechnology. After being stained, nucleic acids will emit fluorescence under ultraviolet light. The target nucleic acid bands are recovered from the agarose gel to complete subsequent research and analysis. After the target nucleic acid is separated from other nucleic acids by agarose gel electrophoresis, the target nucleic acid needs to be recovered by cutting. The commonly used method at present is to cut the target nucleic acid fragment bands with a conventional scalpel on a gel imaging instrument. However, when recovering multiple gel bands at the same time, because conventional scalpels can only cut one at a time, and long-term ultraviolet light exposure will cause damage to the nucleic acid, and people are directly exposed to ultraviolet light to cut the gel manually, so when cutting the gel, the human body will also be damaged by long-term ultraviolet light exposure. Utility Model Content

[0012] The technical effect of adopting the above further solution is: by arranging a UV light strip on the double-headed stud, the UV lamp of the glue irradiator can be replaced, so that the glue cutting operation can be completed more quickly.
[0013] As a preferred embodiment, a control switch for controlling the heating wire switch is arranged on the handle.
[0014] The technical effect of adopting the above further solution is that the rubber cutting temperature of the cutting tool can be adjusted according to the working temperature to prevent the rubber cutting effect from being poor when the temperature is low.
[0015] Compared with the prior art, the advantages and positive effects of the utility model are:
