Microplate mounting stand, and analyte testing/observing apparatus equipped therewith
View Patent ↗An analyte testing/observing apparatus includes a microplate mounting stand 10 which supports at least one of microplates 27 having a plurality of wells 27 a for accommodating an analyte and microplates 28 each having a plurality of wells 28 a for accommodating a reagent, and which includes a retractable shutter 20 for covering a surface of the at least one microplate mounted on the mounting stand 10 . When the dispensing work is stopped, the shutter 20 is closed and lowered, so that the shutter 20 comes into contact with the surfaces of the microplates, to thereby prevent evaporation and drying of the analyte and the reagent accommodated within the wells before being dispensed.
1. A microplate mounting stand for mounting thereon at least one microplate having a plurality of wells, the mounting stand comprising a flexible sheet shutter for covering a surface of the at least one microplate mounted on the mounting stand and an opening-closing mechanism for moving the shutter between a position where the shutter covers the at least one microplate and a position where the at least one microplate is uncovered; and
opposing side plates with respective guide grooves which receive opposing edges of the shutter and guide the shutter in horizontal movement relative to the at least one mounted microplate and a member extending transversely to the side plates and having a guide groove with an arcuate surface which receives and bends the shutter from horizontal to vertical.
2. An analyte testing/observing apparatus comprising:
a microplate mounting stand which supports at least one microplate having a plurality of wells;
a dispensing mechanism for transferring analyte and the reagent from the wells of the at least one microplate to other wells or containers; and
a testing/observing section for testing/observing a reaction between the analyte and the reagent,
wherein the microplate mounting stand includes:
a flexible sheet shutter for covering a surface of the at least one microplate mounted on the mounting stand and an opening-closing mechanism for moving the shutter between a closed position where the shutter covers the at least one microplate and an open position where the at least one microplate is uncovered; and
opposing side plates with respective guide grooves which receive opposing edges of the shutter and guide the shutter in horizontal movement relative to the at least one mounted microplate and a member extending transversely to the side plates and having a guide groove with an arcuate surface which receives and bends the shutter from horizontal to vertical.
