The invention discloses a detachable
burette convenient for internal cleaning, and relates to the technical field of
titration equipment. The detachable
burette comprises a fixing mechanism; the uppersurface of a first fixing ring is rotationally connected with a first
threaded rod; a moving block is in threaded connection with the
peripheral side surface of the first
threaded rod; one side of the moving block is fixedly connected with a capacity scale; a
liquid storage mechanism is in clearance fit with the inner wall of the first fixing ring; an internal thread groove is fixedly connected to the inner wall of a first
liquid storage pipe close to the top end; and the upper surface of a hollow circular truncated cone is fixedly connected with a second
liquid storage pipe. Through the design of the first liquid storage
pipe, the control valve, the second liquid storage pipe, the third liquid storage pipe and the fixing mechanism, the
burette can be rapidly disassembled and assembled, the interior of the burette is convenient to clean, the burette cleaning efficiency is greatly improved, meanwhile, through the arrangement of the control valve, a
titration reagent can be convenientlyadded into the burette, the phenomenon that a
reagent bottle is directly held by a hand to cause flow backward is reduced, and
reagent leakage is effectively avoided.
