초록 ▼

An assay tray assembly and an assay tray primarily for chromatographic analysis has a plastics moulded test tray 1 mounted on a plastics moulded collection tray 72, The test tray has a spaced array of chambers 3 disposed as per a microtiter plate, Each chamber has a bottom outlet port 5 formed by a flange 8 which retains within the chamber a chromatographic medium to which test liquid deposited in the chamber is to be subjected for the percolate or eluate liquid to emerge from the respective outlet ports, The collection tray 72 has a spaced array of wells 16 disposed as per a microtiter plate to correspond with the chambers 3 and the tray 14 is mounted on the tray 72 for each chamber to communicate with a corresponding well 16. Each chamber 3 has a tubular spigot part 12 which extends into the respective well 16 to alleviate cross contamination of the liquid derived from the outlet ports 5.The depth of entry of the tubular spigots 12 into their respective wells 16 is restricted by abutment between the bottom of the test tray with the top of the collection tray, The volume of each well 16 beneath the tubular spigot it receives is adequate to accommodate all of the eluate or percolate derived from the chamber 3 with which it communicates to alleviate liquid on the spigot parts from dripping into wells with which those tubular spigots are not associated (and thereby cause cross contamination) when the trays are separated for analysis of the percolate or eluate.

An assay tray assembly comprising a one piece plastics moulded test tray removably mounted in overlying relationship in engagement with a plastics moulded collection tray; the test tray having a spaced array of discrete identical upstanding chambers to accommodate a predetermined volume of liquid for analysis, each chamber being formed with a top opening and a cylindrical lower part length which communicates with a bottom opening for the flow therethrough of the liquid, said bottom opening being formed as an outlet port by an inwardly directed annular flange provided in a downwardly projecting tubular spigot for the respective chamber; each said chamber carrying in its cylindrical lower part length a separation medium to which the liquid is to be subjected during its said through-flow and which separation medium is in cylindrical face-to-face contact with the cylindrical lower part of the chamber in which it is carried and is retained in that chamber by abutment with said flange; the collection tray having discrete upstanding wells each with an upwardly opening mouth, said wells corresponding in number to the chambers and having their mouths disposed in a spaced array corresponding to that of the tubular spigots; the tubular spigots being received one in each of said well mouths with the outlet ports of the respective chambers located centrally in the respective well mouths for the respective wells to collect liquid emanating from the chambers and to alleviate cross contamination between such liquids and wherein abutment means is provided between the trays to restrict the depth of entry of the tubular spigots into the wells whereby the volume of a liquid which is received by a well from the chamber communicating with that well is less than the volume of each well below the tubular spigot it receives.
