Claim:
A microplate, comprising: an upper plate including a top surface, a body, and a bottom surface, where: the top surface has located thereon a sealing substance which has one or more fluid delivery-removal sealing interfaces where each fluid delivery-removal sealing interface has at least two fluid inlet ports and at least one fluid outlet port; and the body having one or more fluid delivery-removal channels extending therethrough where each fluid delivery-removal channel has at least two fluid inlet channels and at least one fluid outlet channel which are respectively aligned with the at least two fluid inlet ports and the at least one fluid outlet port that are located within the corresponding fluid delivery-removal sealing interface of the sealing substance; and a lower plate including a top surface which is attached to the bottom surface of the upper plate such that one or more flow chambers are present therebetween, where each one of the flow chambers is in fluid communication with a corresponding one of the fluid delivery-removal channels extending through the body of the upper plate and where each of the flow chambers further includes: a first flow restrictor associated with one of the corresponding fluid inlet ports; a second flow restrictor associated with another one of the corresponding fluid inlet ports; a central portion having one corner of one end associated with the first flow restrictor and another corner of the one end associated with the second flow restrictor; and an outlet portion associated with the corresponding fluid outlet port and an opposite end of the central portion, wherein the opposite end is directly opposite from both an opening of the one corner and an opening of the another corner associated with the one end of the central portion.
