Description

TECHNICAL FIELD The present invention relates to a test microplate used for serum test, tissue culture test and the like.

Conventional technology Microplates that are used to perform various tests by inserting test reagents and samples such as serum in small amounts, or when performing tissue culture tests by adding a small amount of tissue to be cultured have a rectangular planar shape. It has a large number of dents on its upper surface into which a specimen or tissue for the purpose of examination is put.

Then, when the microplate is used, the microplate is placed on a workbench, a sample or a tissue is put into the recess little by little, and then various treatments are performed. In the test of specimens such as blood and serum, work such as adding a test reagent and stirring is further performed, and in tissue culture, there is work such as placing in a thermostatic chamber and performing tissue culture.

When testing a sample for the purpose of testing, when stirring the sample and test reagent in the recess of the microplate with multiple stirring rods, the microplate moves and the sample and test reagent spill from the recess, or There is a case where it goes into the other recess from one recess. In addition, when a microplate containing a sample and a test reagent or a microplate containing cultured tissue is placed in a temperature-controlled room for reaction, arranging the microplates side by side on a flat surface saves a very large space. I need. Therefore, the microplates may be stacked, but when the microplates are stacked, the upper surface of the microplate is sealed by the upper microplate, which has a drawback that air flow is deteriorated.

Further, when the used microplates are washed and drained and dried, a large number of microplates are set up one by one to be drained and dried, and the draining and drying work takes up many places and is difficult.

Thus, it has a plurality of test chambers, having a skirt that surrounds at least a portion of its perimeter, the skirt having upper and lower abutment surfaces to allow stacking of a plurality of similar test trays, with openings A test tray provided on a skirt for ensuring removal of sublimated water is proposed in Japanese Patent Laid-Open No. 59-175872.

However, this product promotes drying when many are stacked, and the openings are formed on the side surface of the tray and the sides of the skirt. Is not possible, and the efficiency of drying is poor simply by evaporating the water through the opening in the stacked state, and it cannot be used to fix this opening to the fixing base, and in order to fix it, hold it on the base part. The structure is complicated because other means such as providing an arm or connecting a number of trays is required.

DISCLOSURE OF THE INVENTION The object of the present invention is to facilitate draining and drying work after washing, and to fix the microplate so that it does not move when the microplate is placed on a workbench and working. It is an object of the present invention to provide an inspection microplate having a simple structure in which air also flows to the upper surfaces of the superposed microplates when the microplates are stacked.

Means for Solving the Problems In the inspection microplate of the present invention, a side wall is provided on the back surface periphery of a rectangular horizontal plate, and a plurality of recesses shallower than the height of the side wall are formed in the horizontal plate. The holes penetrating in the up-down direction are provided at both corners on at least one of the diagonal lines of the above, thereby solving the above problems.

Action When dispensing a sample, test reagent, or cultured tissue for the purpose of testing into the recess of the microplate, or when stirring the sample or test reagent, fit the above holes into the pins provided on the fixing table. Perform the work by fixing the microplate to the fixing table. As a result, the microplate does not move or shake and stable work can be performed.

Also, when microplates are stacked and a heating reaction is required in a temperature-controlled room, the above-mentioned holes serve as air circulation holes and the upper surface of each microplate is not sealed, and communicates with the outside to the upper surface of each microplate. Since air at a constant temperature in the constant temperature chamber circulates constantly, the specimen, the culture tissue, and the like placed in the depressions of each microplate react under uniform conditions.

When the microplate is used and then washed and drained and dried, a large number of microplates can be hung through the above-mentioned holes to drain and dry.

Embodiment FIG. 1 is a perspective view of an embodiment of the present invention, showing a state in which the inspection microplate of this embodiment is placed on a fixed base 6.

The microplate 1 has a rectangular horizontal plate 7, a side wall 8 is formed on the peripheral edge of the back surface of the horizontal plate 7, and the horizontal plate 7 is bent to form a large number of recesses 2 slightly shallower than the height of the side wall 8. A sample or a cultured tissue for the purpose of inspection is placed in the depression 2.

Further, in the microplate 1 of the present embodiment, the horizontal plate 7 is cut out at the four corners, and the holes 3 penetrating in the vertical direction are formed. The feature of the present invention is that the holes 3 are provided, and the holes 3 fix the microplates 1 to the pins 4 provided on the fixing table 6 placed on the working table, and the microplates 1 are stacked. Used for circulation of air when
It is used to suspend the microplate 1 when it is drained and dried after washing.

That is, when the microplate 1 is used, the microplate 1 is placed on the fixed base 6 which is slightly larger than the microplate 1, and the four of the four vertically arranged at the four corners of the upper surface of the fixed base 6 are placed. When each of the holes 3 is fitted into the pin 4, the pin 4 comes into contact with the inner surfaces of the two side walls 8 of the microplate 1 which intersect with each other, and the microplate 1 is fixed on the fixing base 6. Therefore, since the microplate 1 does not move or shift, the work is facilitated, and particularly when the sample and the test reagent are stirred by the stirring rod, the microplate 1 does not shift or move, which facilitates the work.

Further, when the microplate 1 into which the specimen or the cultured tissue is dispensed is reacted in a thermostatic chamber, even if the microplates 1 are stacked, the holes 3 become air circulation holes as shown in FIG. Since air flows into the upper surface of each hole plate 1 through the holes 3 as indicated by an arrow in FIG. 2, the upper surface of each microplate 1 is always kept at a constant temperature.
Therefore, the specimen and the cultured tissue put in each recess 2 of each microplate 1 are reacted under the same condition.

Furthermore, the microplate 1 used for research and inspection experiments
When a large number of the microplates 1 are to be drained and dried, one of the holes 3 of each microplate 1 may be passed through a rod 5, and the microplates 1 may be washed and then hung and dried as shown in FIG. Very convenient and efficient.

When the corner of the horizontal plate 7 is cut out to form the hole 3, it may be cut out linearly or in an arc as shown in FIGS. 4 (a) and 4 (b). Also, holes may be formed in the corners of the horizontal plate 7 instead of the notches.

Although the holes 3 are formed in the four corners of the horizontal plate 7 in the above embodiment, holes may be formed in both corners on one diagonal line. Even in this case, since the two pins provided on the fixing base contact the inner surfaces of the two side walls 8 of the microplate 1 which intersect, the microplate 1 is securely fixed to the fixing base.

Further, when the microplate 1 is washed, when the microplate 1 floats on the surface of the washing liquid, the hole 3 becomes an air outflow hole, and air is released, so that the microplate 1 sinks into the washing liquid without fail. Will also be easier.

Advantageous Effects of Invention The microplate for inspection of the present invention is provided with a side wall on the back surface periphery of a rectangular horizontal plate, and a recess shallower than the height of the side wall is formed in the horizontal plate, and holes are formed in at least one diagonal corner of the horizontal plate. Since it was drilled, the microplate can be easily fixed simply by passing the pin erected on the upper surface of the fixing base through the hole, and the microplate moved into the recess when stirring. When there is no risk of samples spilling and when microplates are stacked and react in a temperature-controlled room, the holes become air circulation holes, and the air inside the temperature-controlled room is introduced to the upper surface of each stacked microplate. The specimen and the cultured tissue placed in each depression of the plate will react under the same conditions.

Further, when the used microplate is washed and drained and dried, a rod can be passed through one of the holes to hang a number of microplates in parallel and drained and dried, so that the draining and drying work can be efficiently performed. It is possible to shorten the drying time.

Further, since the holes formed in the horizontal plane also serve as the above-mentioned fixture insertion hole, air introduction hole and suspension attachment hole, the structure is extremely simple and the cost is low.
