Description

ELISA plate incubator

Technical Field

The utility model relates to the technical field of enzyme-linked immunosorbent assay, in particular to an ELISA plate incubator convenient for incubation and later cleaning.

Background

The ELISA is a common antibody or antigen determination method in immunological experiments, and has the characteristics of strong specificity and high sensitivity, so that the ELISA has an indispensable position in clinical application and laboratory research.

The enzyme label plate commonly used in the market is a 48-hole enzyme label plate, a 72-hole enzyme label plate and a 96-hole enzyme label plate, and the existing enzyme label plate (shown in fig. 1) is composed of a plate frame 100 and a coating groove 200 movably inserted on the plate frame 100. In the case of performing an ELISA assay, the conventional incubator can only incubate the ELISA plate, and after incubation, the plate rack 100 is reusable, so that the coating tank 200 is removed from the plate rack 100, and then a new coating tank 200 is refilled for reuse.

Because the number of plate holes (48 holes, 72 holes or 96 holes) on the ELISA plate is large, and the coating groove 200 is always in a frustum-shaped structure with large top and small bottom in order to ensure stable insertion, the coating groove 200 is removed from bottom to top one by one, the operation is very complicated, and the cleaning time and the cleaning difficulty are greatly increased; meanwhile, the used coating tank 200 also often remains sample liquid, so that the liquid splashing phenomenon is easy to occur in the cleaning and dismantling process, and the pollution to the experimental environment and the operation risk of operators are greatly increased.

As shown in fig. 2 and 3, the ELISA plate incubator of the utility model comprises an incubator body consisting of a lower incubator body 1 and an upper incubator cover 2 hinged on the lower incubator body 1; an incubation unit is arranged in the incubation box body, and a control unit for controlling the incubation unit to work is arranged on the outer wall of the incubation box body. Specifically, the incubation unit is arranged in the lower box 1, and comprises an electric heating element 3 (such as an electric heating wire with a circulating fan) and a temperature sensing element 4 (such as a temperature sensor), while the control unit is arranged on the right side wall of the lower box 1 (of course, the control unit can also be arranged on the left side wall of the lower box 1), and comprises a touch panel 5 and a power switch 6, the electric heating element 3 is used for heating the chamber inside the incubator body and keeping the temperature inside the incubator constant, the temperature sensing element 4 is used for monitoring the temperature of the chamber inside the incubator body in real time, the touch panel 5 is used for displaying the temperature of the chamber inside the incubator body in real time, the temperature can be regulated at any time, the heating time is set, and the power switch 6 is used for controlling the starting or closing of the incubation function of the whole incubator body.

The lower chamber 7 with an upper opening is arranged on the lower box body 1, the upper box cover 2 is provided with an upper chamber 8 with a lower opening corresponding to the lower chamber 7 in an adapting way, and the lower chamber 7 and the upper chamber 8 are communicated into a whole through the adapting and buckling of the lower box body 1 and the upper box cover 2, so that a chamber inside the incubator body is formed. At this time, a clamping plate 9 is horizontally arranged at the upper part of the lower cavity 7 of the lower box body 1, and a step-shaped clamping hole 10 for adapting to the clamping enzyme label plate is formed in the clamping plate 9; and the front wall of the lower box body 1 is also provided with a drawer 11 which can be horizontally pulled, the drawer 11 is provided with an upper opening receiving groove 12 which is right opposite to the lower part of the step-shaped clamping hole 8, and the front wall of the drawer 11 is provided with a grab handle 13 which is convenient to hold. An elastic pressing plate 14 capable of being pressed vertically downwards is arranged on the top wall of the upper box cover 2, specifically, a mounting hole 15 is formed in the top wall of the upper box cover 2, the elastic pressing plate 14 is adaptively clamped in the mounting hole 15, a plurality of groups of pressure springs 16 are uniformly distributed at the edge of the bottom surface of the elastic pressing plate 14, the axis of each pressure spring 16 is kept vertical to the elastic pressing plate 14, and meanwhile, the lower end of each pressure spring 16 is fixed on the inner edge of the lower opening of the upper box cover 2, so that the horizontal pressing and automatic rebound reset of the elastic pressing plate 12 are easily realized. In addition, a plurality of longitudinal jacking columns 17 are uniformly distributed on the bottom surface of the elastic pressing plate 14, and the arrangement of the longitudinal jacking columns 17 is in one-to-one correspondence with the plate holes of the ELISA plate clamped on the step-shaped clamping hole 10, so that the longitudinal jacking columns 17 can be driven to move by the movement of the elastic pressing plate 14, and the longitudinal jacking columns 17 can move downwards to a first position extending into the plate holes of the ELISA plate and move upwards to a second position retracted into the upper box cover 2.
