Telescopic test-tube brush for agricultural strain culturing

Abstract

The invention discloses a telescopic test-tube brush for agricultural strain culturing. The telescopic test-tube brush comprises a main hollow rod and an extension rod, and a hanging ring is arranged on the upper surface of the main hollow rod. The telescopic test-tube brush for agricultural strain culturing is simple in structure, diversified in functions, convenient to operate and capable of bringing convenience to a tester in cleaning of test tubes; by the aid of the hanging ring, the telescopic test-tube brush can be hung at a position, which is convenient for the tester to fetch and use; by the aid of a system formed by combination of a spring, a hollow screw rod and the like, the test tubes can be cleaned semi-automatically, thus effort is saved and cleaning time is saved greatly; by the aid of the extension rod which is adjustable telescopically, convenience in use of the telescopic test-tube brush is increased, a radian of an elastic rod can be adjusted according to the size and the shape of the test tube, and applicability of the telescopic test-tube brush is enhanced; by the aids of a semi-spherical sponge and an annular sponge pad which are arranged on the extension rod, water left on an inner wall of the test tube after cleaning can be absorbed completely, airing of the test tube after cleaning is omitted, and convenience in use of the telescopic test-tube brush is further increased.

Description

technical field [0001] The invention relates to the technical field of experimental equipment for cultivating agricultural products, in particular to a retractable test tube brush for cultivating agricultural strains. Background technique [0002] As a common laboratory tool, test tube brushes are widely used in various laboratories. However, the existing test tube brush technology has a single function and cannot remove the stains on the test tubes finely. The test tube burst, causing a lot of trouble for the experiment. Especially before and after the cultivation of agricultural strains, the test tubes and other instruments used need to be carefully cleaned. At present, most of the existing test tube brushes have a fixed shape and a certain bristle density, which cannot be adjusted according to the size of the test tube and the degree of dirt on the inner wall of the test tube. , only use the fixed bristles to wipe back and forth for cleaning. For dirty places, the test t...

[0002] As a common laboratory tool, test tube brushes are widely used in various laboratories. However, the existing test tube brush technology has a single function and cannot remove the stains on the test tubes finely. The test tube broke, causing a lot of trouble for the experiment

Especially before and after the cultivation of agricultural strains, the test tubes and other instruments used need to be carefully cleaned. At present, most of the existing test tube brushes have a fixed shape and a certain bristle density, which cannot be adjusted according to the size of the test tube and the degree of dirt on the inner wall of the test tube. , only use the fixed bristles to wipe back and forth for cleaning. For dirty places, the test tube brush needs to be wiped back and forth many times. The surroundings of the round-bottomed flask used for the culture experiment often cannot be cleaned, which brings great inconvenience to the experimenter. The experimenter caused a great inconvenience
