Abstract

See full text

An apparatus useful in the addition of reagents in small quantities to micro reaction systems is described. The apparatus enables liquids to be dispensed within a narrow desired area of a receiving tube or other receptacle from a needle while avoiding undesired contact with tube walls. Guide means control the position of the needle with respect to the tube. The apparatus is particularly useful in connection with a radioimmune assay system wherein radioactive labelled protein is delivered to a tube.
