ABSTRACT:
A pipetter is connected to a hypodermic needle by an adapter. The adapter includes a conduit with male and female ends and a predetermined volume. The female end of the conduit is dimensioned to receive the end of the pipetter to form a substantially air-tight friction fit. The male end of a conduct is dimensioned to be inserted into the needle holder to form a substantially air-tight friction fit. The volume of the conduit is greater than a volume of the fluid to be transferred. The adapter allows one to combine the advantages of a hypodermic needle with the superior volumetric measuring capabilities of a pipetter, while eliminating the waste associated with disposable syringes.
