There is disclosed a microplate affording an array of discrete, separate sample wells in which each sample well consists of a well of a first polymer composition, the well having side walls and a base, and being located in a matrix of a second polymer composition, the second polymer composition being opaque, the said matrix shrouding the side walls of the said well and extending beyond the ends of the side walls of the wells, each well being thermally bonded to the matrix of the second polymer composition, so as to form an integral structure. There is also disclosed a method of making a microplate which comprises moulding an array of discrete separate wells of a first polymer composition on a support and then moulding a matrix of a second polymer composition around the said wells so that the said polymer compositions are thermally bonded to each other and separating the said integral structure from the support whereby the wells have open ends emerging through one face of the structure, and their other ends closed. |
