Abstract: A burette (10) to receive liquid from an intravenous supply (29) to deliver liquid to a patient via a tube (30). The burette (10) includes a hollow body (11) that is generally cylindrical configuration and that contains a float valve (24). Liquid level in the chamber (12) of the body (11) regulates liquid level within the chamber (12) by engaging an inlet passage (36) or an outlet tube (25).

Abstract: There is provided a burette apparatus having a delivery tube connecting a fluid bag to a burette assembly, via a fluid entry spigot formed in an end cap assembly of the burette assembly, the end cap assembly having a bypass spigot connected to the delivery tube and usually closed by clip, to allow an override for adding liquid to the burette. The end cap assembly closes the upper end of the transparent, cylindrical burette body, into which extends a stainless steel tube extension of the fluid entry spigot, the lower end of the burette body being closed by a lower closure assembly having a check valve and a drip chamber. An outlet tube passes from the drip chamber to the patient via regulating clamp. A float assembly is located in the burette body including an extension rod provided with a resilient cup adapted to engage the open end of the stainless steel tube extension.
