Abstract
Abstract A device which can be used in certain chemical and medical laboratory tests wherein very small quantities of fluids (such as micro-liters) are used (as in such as the Rubacell test for immunity to Rubella). In performing such tests the small quantities are contained in a container called a "V" plate, or like container, which container has small wells to contain the fluids and small upward depressions on its bottom aspect.
