US Patent 10173218 Microplate and methods for making the same

A microplate (10) includes a carrier (12) having a plate (20) and an annular perimeter wall (30) to define a recess (34). An array of holes (26) extends through the plate (20). A tape piece (16), die cut from a flexible tape (60) includes an array of wells (54) each extending through and having an opening (56) extending into the well (54). The array of wells (54) has a number and locations corresponding to the array of holes (26). The openings (56) have sizes corresponding to the holes (26). An upper surface (50) of the tape piece (16) is abutted with and bonded to the bottom face (24) of the plate (20) with the openings (56) corresponding to the array of holes (26). The slideable receipt of an annular outer periphery (58) of the tape piece (16) insures that the array of wells (54) are aligned to correspond to the array of holes (26) as die cutting of tape piece (16) insures that the array of wells (54) are at consistent positions relative to the annular outer periphery (58).
