The great demand, the frequent loss, and the inability to readily procure suitable beads for the defibrination of blood has prompted the designing of this simple apparatus, which has given excellent results, and which may be of interest and value to those engaged in the class of work necessitating such treatment of blood.
The apparatus consists of an ordinary Erlenmeyer flask (A) with a cork to fit, and a piece of looped wire, preferably copper, as copper will not rust and is readily cleaned.
The wire (B) may be bent into simple loops or, as set forth in the drawing, may be arranged as an elongated spiral with the two outer loops connected therewith at the top and bottom, the spiral being in the center. This tends to impart more or less rigidity to the structure and, the wire being flexible, is easily introduced into the flask. The upper process
