Top Of The Glass: Bottletop Burettes are Indispensable in Today's Laboratory

Date: March 1, 1999 Table of Bottletop Burettes Dispensing precise quantities of aqueous solutions has always been one of the more frustrating and messy jobs in the laboratory. Limited by manual operations that require careful attention and a steady hand, dispensing and titrating fluids remains one of the least sophisticated and most common procedures in the laboratory, responsible for introducing margins of error that are not insignificant when considered over the course of multiple readings.

Dispensing precise quantities of aqueous solutions has always been one of the more frustrating and messy jobs in the laboratory. Limited by manual operations that require careful attention and a steady hand, dispensing and titrating fluids remains one of the least sophisticated and most common procedures in the laboratory, responsible for introducing margins of error that are not insignificant when considered over the course of multiple readings.

Only recently, with the advent of bottletop burettes, could scientists dispense liquid while making precise measurements of fluid volume. Previously a four-step process was required: dispense the desired amount of liquid, carefully measure the given quantity, add or subtract the desired portion, and pour the remainder into the reaction vessel. This complicated and time-consuming process, which frequently results in drips and spills, has been reduced to a single step with the use of bottletop burettes....
