A titerplate for instrumental analysis of liquid samples consists of a plurality of wells in which the walls and bottoms are made of two different materials with different physical properties. This allows the interfacial tension at the surface of the liquid to be controlled in such a way that it is essentially planar, allowing more accurate analysis to be performed on the samples. The bottoms of the wells are preferably made of a transparent material, so that the analysis and observation can be done in the transmission mode. The wells may be formed of radiation-absorbing material to prevent radiation cross talk between radioactive specimens. An overgarment replaceable film or foil having depressions aligned with the titerplate wells may be utilized to prevent contamination of the titerplate by samples and allow the reuse of the titerplate.

[ We claim:] [1.] A multi-well titerplate assembly for use in conjunction with instrumental analysis of liquid samples, comprising a plurality of individual wells each having a side wall and a bottom, said bottoms being arrayed whereby said bottoms are aligned in a common plane, a plurality of said bottoms being formed as a series of elevations upon a bottom plate said walls being mounted with a friction fit about the periphery of the well bottom of the well and constructed of a compound thermoplast containing a radiation-absorbing material chosen to interact with a liquid sample to be placed within the well whereby the resulting interfacial tension between the sample to be placed and the well wall results in a generally planar sample surface, the material for the well bottom being a thermoplastic material chosen to allow observation and/or analysis of the sample therethrough.
