Abstract
A liquid sample holder having a fluid sample receptacle bounded by two substantially parallel sheets. The parallel sheets define a fluid analysis area, and adjacent to that area is a peripheral overflow. Air bubbles are trapped in the peripheral overflow because the distance between the plates is smaller than the depth or thickness of the peripheral overflow.
