The utility model content
The utility model causes liquid feeding inhomogeneous for the cleaning head that solves the prior art ELIAS microplate washer easily, and waste liquid refluxes, and causes imbibition clean or produce the technical matters of cross pollution, and a kind of cleaning head of ELIAS microplate washer is provided.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is the cleaning head of a kind of ELIAS microplate washer of design; Comprise the cleaning head main body, be arranged on fluid injection pin on the cleaning head main body, be arranged on aspirating needle on the cleaning head main body, be arranged in the cleaning head main body and be positioned at said fluid injection pin top the fluid injection chamber, be arranged on the cleaning head main body and be positioned at the imbibition chamber and the cleaning head adapter that is arranged on cleaning head main body side and links to each other on said aspirating needle top with said imbibition chamber, said imbibition chamber is being provided with the liquid storage cylinder towards lower recess with said cleaning head adapter abutting end.
Eight or 12 arrays that become a row to form 96 pins of said fluid injection pin; Said fluid injection chamber is by two semicircles or oval-shaped chamber dimerous up and down; The fluid injection pin stretches into from following semicircle or ellipse, and the upper surface of fluid injection pin is stretched in the top semicircle or ellipse at least.
The every row of said fluid injection pin is independent to communicate with the fluid injection chamber, and each fluid injection chamber is not connected.
The upper surface height of said same row's fluid injection pin is consistent.
Said imbibition chamber all communicates with all aspirating needles.
The bottom of said aspirating needle is provided with chamfering, and the fillet surface of said chamfering is hollow.
The cleaning head of said ELIAS microplate washer also comprises fluid injection chamber that is arranged in the cleaning head main body and is positioned at said washing lotion pin top and the cleaning head that is arranged on cleaning head main body side and links to each other with the said fluid injection chamber transfer tube of intaking.
The utility model is through establishing the liquid storage cylinder towards lower recess in imbibition chamber and said cleaning head adapter abutting end place; Thereby can make and not drain clean backflow waste liquid in sewer pipe or the cleaning head adapter and be housed in liquid storage cylinder; Prevent that it from refluxing through the imbibition chamber, imbibition is cleaner.
