Abstract
Buret apparatus of the type including a buret conduit terminating at one end in a siphon, characterized in that the siphon includes a siphon passage formed on a stopper that is removably mounted in the buret conduit. The improved siphon structure is relatively inexpensive to manufacture, and is less susceptible to breakage than the conventional circular glass siphon devices. The improved apparatus is particularly suitable for use as a precision titrator or dosing device where measurements in the microliter range are required.
