Further, the inner wall of the conduit hole is a rough surface; the inner wall of the conduit hole is a frosted surface or is provided with a plurality of round small protrusions, and the insertion depth of the pump tube is controlled to be kept unchanged by using the friction force of the inner wall.
Further, the outer wall of the lower part is a rough surface; ensure the bottle cap to be closely contacted with the volumetric flask.
Further, the joint of the first fitting and the second fitting is the upper part of the bottle cap.
The utility model discloses use the dead lever as the axle, can make the bottle lid open or closed, because torsion spring's elasticity can be opened in one side of keeping away from torsion spring hard a little, then put into the pipe hole with the pump line, after adjusting suitable degree of depth, closed bottle lid guarantees the fixed of pump line through torsion spring's elasticity, then covers on the volumetric flask. The bottle cap has the advantages of simple disassembly, no need of contacting the outlet part of the pump pipe and prevention of cross contamination.
The bottle lid on have cylindrical pipe hole, pipe hole diameter ratio pump line diameter is a bit bigger, the pump line can pass circular through-hole absorb the volumetric flask in solution, can solve the uncovered drawback of placing of volumetric flask in the current test procedure, can prevent volatilizing and polluting of reagent in the bottle, to small or the less volumetric flask of solution, even being knocked down, also can prevent that solution from flowing to the mesa on, reduce the potential safety hazard. And the inner wall of the hole of the cylindrical conduit is a frosted surface or is provided with a plurality of round bulges which are rough surfaces, the insertion depth of the pump tube is controlled to be kept unchanged by friction force, and the situation that the pump tube is contacted with insoluble substances deposited at the bottom of the bottle when the insertion depth is too deep or the pump tube cannot suck the solution or slides out of the measuring bottle to influence the test result when the insertion depth is too shallow can be prevented. The bottle cap is simple in design, easy to operate, firm and durable, the pump pipe can be prevented from being in the bottle cap by opening or closing the opening through the bottle cap, the bottle cap is simple to disassemble, and the bottle cap does not need to contact the outlet part of the pump pipe, so that cross contamination is prevented.
