Eliminates H E M E - M C M Titration Completely redesigned, this new version of the Gilmont Ultra-Microburet provides vastly improved means of achieving rapid titration. It accomplishes this with complete elimination of time consuming and nerveracking manipulation. This altogether improved Ultra-Microburet is now so simple to operate that it is actually easier to use than the ordinary buret of the analytical laboratory, besides being capable of a higher degree of precision.
these are 5 of the redesign
features

A precision ground plunger, having the required diameter so that the dial micrometer gauge reads directly in volume units, displaces mercury in a reservoir sealed off by a sili cone rubber gasket, contained in an aluminum bushing. The displaced mercury in turn forces exactly the same volume of titrating liquid through a fine orifice immersed in the solu tion being analyzed, which may be stirred by a fine stream of air bubbles. «Gilmont.
