A New and Simplified Micrurgical Apparatus Especially Adapted to Single Cell Isolation

Abstract

A short history of the development of micrurgical instruments precedes the description of the author''s apparatus. The features peculiar to it offered are, its accuracy, durability, simplicity, adaptability to all kinds of micrurgical manipulations, and its low cost. The principle involved is a ball and socket arranged as a universal joint. Movements in any plane are effected by individual movement cylinders. The instrument is intended primarily for single-cell isolation in bacteriology, attention being directed to pipette changing, movement distances, and a quick means of returning the pipette to the isolation field.
