Micro-titer plate and method of making same

Abstract

The present invention provides a method of manufacturing a micro-titer test plate, said method comprising the steps of: (a) providing a first and second part, said first part comprising a plurality of wells connected to each other and said second part comprising a plurality of spouts connected to each other, said spouts conforming in arrangement and number to said wells of said first part (b) placing a filter sheet that extents across each of said wells of said first or placing a filter sheet that extends across each of said spouts of said second part (c) separating from said filter sheet filter means that conform in shape, size, arrangement and number to either the bottom opening of the wells of said first part or, to said upper openings provided at the first end of the spouts; (d) placing said filter means in each of the bottom openings of the wells or in each of said upper openings provided at the first end of the spouts; (e) removing the remainder of said filter sheet from which the filter means have been separated; (f) bringing said first part and said second part in contact with each other such that the bottom opening of said wells face the first end of said spouts; and (g) bonding said first part and said second part to each other.

         11 . A micro-titer plate comprising a plurality of sample containers connected to each other, each sample container having one or more side walls enclosing the interior of the sample container, an open upper wall defining an inlet opening and a bottom wall having an opening defining an outlet opening, said outlet opening being enclosed by a spout extending in the axial direction of the sample container, wherein the sample containers are defined by a first and second part, said first part comprising a plurality of wells connected to each other and each having an upper end that is open and that will define the inlet opening of said sample containers and an opposite bottom opening and said second part comprising a plurality of spouts connected to each other, said spouts conforming in arrangement and number to said wells of said first part and each spout enclosing at a first end an opening that will define the outlet opening of said sample containers, and each spout optionally having an upper opening at said first end for receiving a filter means.
