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.
Claims11
An adapter for connecting a pipetter to a hypodermic needle having a holder, comprising:
- a conduit having a male end and a female end and a volume;
- the female end having means for receiving an end of the pipetter so that a connection between the female end and the end of the pipetter includes an air-tight friction fit;
- the male end of the conduit having means for inserting into the holder of the hypodermic needle so that a connection between the male end and the holder includes an air-tight friction fit;
- wherein
- the volume of the conduit is greater than a volume of a fluid to be transferred.
