Description

Deep-well plates

Technical field

The microplate that the utility model uses when relating to a kind of processing, transfer and storage liquid sample relates in particular to a kind of deep-well plates.

Background technology

Deep-well plates is used for handling, shifts and the storage liquid sample, is widely used in biological field such as cell cultures etc. at present; Be used for the storage of laboratory fluids such as polar organic solvent, acidity and basic solution; The motherboard sampling and storage sample, mechanical sampling and the automatic liquor-transferring system that are used for identification systems; Be used for automatic dilutor, sample injector; Be used for the blood agglutination reaction, the mensuration of antibody titers.Various field is to the environment requirement difference, and it is big etc. that this just requires deep-well plates to have good tolerability, temperature tolerance, physical strength.Usually hole bottom can be done circularly, improve the rate of recovery of sample, but circular bottom be difficult for gaining in strength, and causes the bottom to be prone to slight crack even to break and the phenomenon of leakage occurs, causes sample to run off.

The utility model content

Technical problem to be solved in the utility model provides a kind of deep-well plates, and is simple in structure, has higher physical strength, and the bottom, hole that is used for the liquid storage body on the orifice plate is difficult for producing slight crack or breaking.

For solving the problems of the technologies described above, the utility model provides a kind of deep-well plates, comprise the quadrangular frame that surrounds by four lateral frame boards with certain altitude, the cross section of described quadrangular is a rectangle, it is characterized in that, the orifice plate that is connected with described frame around comprising is evenly distributed with the square hole that has at the bottom of the U-shaped on the described orifice surface, the bottom at the bottom of the U-shaped of described square hole is provided with a columnar structure.

The height of described orifice plate upper aperture is less than the height of described frame.

The mutual shared hole wall of the square hole part of adjacent in twos described square hole, independent separately at the bottom of the U-shaped of described square hole.

Outer wall connects by dowel at the bottom of the U-shaped of adjacent described square hole, increases physical strength.

Described columnar structure is a right cylinder.

Be connected with described frame by stiffening web around the described orifice plate, physical strength is big.

Described quadrangular frame is oblique quadrangular frame, less end of described oblique quadrangular frame and described orifice surface smooth connection, the bigger end of described oblique quadrangular frame can hold the less end of described oblique quadrangular frame, and a plurality of deep-well plates can be fastened mutually, vertically is superimposed.

The bigger end of described oblique quadrangular frame is provided with position limiting structure, and guaranteeing when deep-well plates is superimposed, the columnar structure of bottommost does not contact with orifice surface on the deep-well plates of following one deck at the bottom of the square hole U-shaped on the deep-well plates of last layer.Position limiting structure can adopt various ways, can establish shoulder in the oblique bigger end end of quadrangular frame and play position-limiting action, also can play position-limiting action simultaneously by the stiffening web that is connected with frame around the orifice plate, stiffening web the oblique formed plane of the bigger end of quadrangular frame not with deep-well plates on the square hole U-shaped at the bottom of the Plane intersects that constitutes of the columnar structure of bottommost or contact, that is to say that the columnar structure position of bottommost was also low at the bottom of stiffening web was than U-shaped, like this when deep-well plates is superimposed, the deep-well plates of following one deck is not when also contacting with the columnar structure of bottommost at the bottom of the U-shaped of last layer, just contact with the stiffening web of last layer deep-well plates earlier, limit the position of next layer depth orifice plate by stiffening web.

The bigger end of described oblique quadrangular frame is provided with recess, is convenient to the location.

The beneficial effect that the utility model reached: deep-well plates of the present utility model is the square hole deep-well plates, and is simple in structure, has higher physical strength, and can conveniently superpose, easily the location.The bottom that is used on the orifice plate at the bottom of the U-shaped of square hole of liquid storage body is provided with columnar structure, has strengthened bottom strength at the bottom of the U-shaped, makes deep-well plates bottom after cryogenic freezing be difficult for producing slight crack or breaking, and avoids the generation of the phenomenon of leakage.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, deep-well plates with one 96 holes is that example illustrates structure of the present utility model, deep-well plates is made by polypropylene material, comprise the oblique quadrangular frame 1 that surrounds by four lateral frame boards, the orifice plate 2 that is connected with frame 1 all around, orifice plate 2 is a rectangle, is evenly distributed with 8 row on orifice plate 2

surfaces

21,12 of every row amount to 96 square holes 22 at the bottom of having U-shaped, and 23 bottom is provided with a cylindrical columnar structure 24 at the bottom of the U-shaped of square hole 22.

The height of orifice plate 2 upper aperture 22 is less than the height of frame 1.

The mutual shared hole wall 25 of the square hole part of adjacent in twos

square hole

22,23 is independent separately at the bottom of the U-shaped of square hole.

Be connected with frame 1 by stiffening web 3 around the orifice plate 2.

A tiltedly less end 11 and orifice plate 2 surperficial 21 smooth connections of quadrangular frame, tiltedly the bigger end 12 of quadrangular frame can hold the less end 11 of oblique quadrangular frame, and a plurality of deep-well plates can be fastened mutually, vertically is superimposed.

Tiltedly the bigger end 12 of quadrangular frame is provided with position limiting structure 4, and guaranteeing when deep-well plates is superimposed, the columnar structure 24 of 23 bottommosts does not contact with orifice plate 2 surfaces 21 on the deep-well plates of following one deck at the bottom of the square hole 22U shape on the deep-well plates of last layer.Position limiting structure in the utility model adopts and plays position-limiting action simultaneously by stiffening web 3, stiffening web 3 is also low than columnar structure 24 positions of 23 bottommosts at the bottom of the U-shaped, like this when deep-well plates is superimposed, the stiffening web 3 of deep-well plates of following one deck and last layer deep-well plates is inconsistent, can not contact with the columnar structure 24 of 23 bottommosts at the bottom of the U-shaped of last layer.

Tiltedly the bigger end 12 of quadrangular frame is provided with and is used for localized recess 13.

For the ease of distinguishing each hole, establish the foraminous numbering on the orifice plate, be convenient to directed location simultaneously, one jiao of orifice plate is provided with orientation angle 5.

The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection domain of the present utility model.
