Plaque taking device convenient to operate for field of biotechnology

Abstract

The invention discloses a plaque taking device convenient to operate for the field of biotechnology. The plaque taking device comprises a suction head, a suction barrel, a piston rod and a handle. Thesuction head is fixed to the end of the suction barrel through a thread, the handle is arranged at the bottom of the suction barrel, the handle and the suction barrel are integrally manufactured, andan inner cavity of the handle is communicated with an inner cavity of the suction barrel. A button is mounted on one side of the handle, the button and a power rod located in the handle are linked, apower rod guide sleeve for guiding motion of the power rod is mounted on the inner wall of the handle, through holes are formed in the inner wall of the handle, and the two ends of the power rod canstretch out of the through holes. The power rod is of a round-rod-shaped structure, a section of cutting face is arranged on the power rod, and a plurality of power rod teeth are arranged on the cutting face. The plaque taking device has the advantages that the plaque taking device can be operated by one hand, the operation process is convenient and easy, and control is easy; a piston, the suctionhead and the like can be demounted, and can be reused after sterilization operation is carried out; the visual field is not blocked in the operation process, and the efficiency is high.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to an easy-to-operate phage plaque removal device for the field of biotechnology. Background technique [0002] As disclosed in CN207108992U, a microgun for stealing plaque comprises a gun barrel and a plunger, the bottom end of the gun barrel is provided with an opening, and the plunger includes a piston handle, a piston connected in sequence from top to bottom. Rod and piston, the plunger reciprocates inside the gun barrel, and the bottom end surface of the piston handle can reach the upper end surface of the gun barrel, and a vent hole is arranged on the tube wall of the gun barrel, The distance from the center of the vent hole to the top of the gun barrel is not more than half the length of the plunger; when in use, first lift the piston above the vent hole by lifting the piston handle to ensure that the gun barrel inside The air pressure is connected to the atmospheric pressure; t...

Problems solved by technology

[0004] (1) Both hands are required for operation, which is not convenient enough;

[0005] (2) The movement of the piston handle needs power applied by the hand. The key is that sometimes the tapered tube is not kept perpendicular to the culture plate. It is laborious to control the direction of movement of the piston handle by hand;

[0006] (3) The miniature gun is a one-time item and cannot be reused, resulting in a waste of resources
