The utility model relates to the technical field of pipettes, in particular to a pipette accessory. The pipette accessory provided by the utility model solves the technical problem that an ear washing bulb for the pipette accessory in the prior art is inconvenient to operate. A pipette fitting includes an ear washing bulb; the quantifying assembly is arranged on the ear washing bulb; the connecting assembly is arranged on the ear washing bulb; the quantitative assembly is arranged and comprises the supporting device and the batcher, the batcher is provided with the quantitative groove, when the ear washing bulb is pressed, the ear washing bulb is pressed through the quantitative groove, the quantitative groove corresponds to the receding groove, and when the ear washing bulb is pressed, the deformation amplitude of the ear washing bulb is limited by the receding groove and the quantitative groove; therefore, the deformation speed or the deformation amplitude of the ear washing bulb can be prevented from being too large, the ear washing bulb is easy to operate, and the use performance of the ear washing bulb is optimized.

The organ-like chip platform for simulating multi-organ interaction comprises a culture dish, the outer side of the culture dish is covered with a supporting frame, the upper end of the supporting frame is fixedly connected with a guide frame, a first movable guide strip and a second movable guide strip are installed on the guide frame in a sliding mode, and the first movable guide strip and the second movable guide strip are in movable contact with each other. A movable supporting seat is movably arranged at the intersection of the first movable guide strip and the second movable guide strip in a sleeved mode, and an ear washing bulb is inserted into the movable supporting seat. The moving position of the movable supporting seat is manually operated, and the dripping position of the ear washing bulb is adjusted; after the ear washing bulb is taken down to suck a target culture solution, the ear washing bulb is inserted back into the movable supporting seat, a palm is placed on the movable supporting seat, the ear washing bulb is pressed by fingers, so that the ear washing bulb drips the target culture solution into a target position of a culture dish, and the ear washing bulb is positioned by the movable supporting seat, so that hand shaking and inclined dripping are avoided, the operation of a green hand is facilitated, and the accuracy is improved.

The ear washing device comprises an ear washing device body, a water tank, a water receiving cup, a spray head and a water outlet module, a plurality of strip-shaped protruding ribs are distributed on the outer wall face of the lower end of the water tank at intervals in the circumferential direction, the water receiving cup is provided with a containing cavity with an opening in the top, and the lower side of the water tank is inserted into the water receiving cup through size matching. And the strip-shaped convex ribs are propped against the inner wall of the water receiving cup to realize clamping connection. During normal ear washing operation, the water receiving cup can be pulled out from the bottom of the water tank with slight force, the water receiving cup can be used for receiving waste water independently, after use, the ear washing device body with the water tank is inserted into the water receiving cup downwards with force, the strip-shaped protruding ribs abut against the interior of the water receiving cup, and combined operation of the water receiving cup and the ear washing device is achieved. And the occupied space is saved, and the subsequent ear washing device is convenient to carry and operate.

The utility model provides a floating algae precipitation and concentration siphon device which comprises a water storage bottle, a siphon is fixedly inserted into the top end of the water storage bottle, the tail end of the siphon is fixedly connected with an insertion pipe, the bottom end of the insertion pipe is fixedly connected with a horn mouth, and the bottom end of the horn mouth is located in a plankton precipitation bottle. A plankton net is fixedly installed at the bottom end of the horn mouth, a water injection opening is formed in the top end of the water storage bottle, a bottle cap is arranged on the water injection opening, a water drainage pipe is fixedly inserted into the side end of the bottom of the water storage bottle, and a flow controller is arranged on the water drainage pipe. Negative pressure is formed in the siphon through drainage of the water storage bottle, an ear washing bulb is not needed, the risk that liquid in the siphon flows back to damage a sample due to the fact that the negative pressure is lost in the siphon in the siphon process is effectively avoided, the siphon process is more convenient and efficient, the progress of the siphon process can be controlled through the flow controller, and the sampling efficiency is improved. The drainage flow of the water storage bottle is adjusted, and the operability is higher.
