A burette is a volumetric measuring glassware which is used in analytical chemistry for the accurate dispensing of a liquid, especially of one of the reagents in a titration. [4] The burette tube carries graduated marks from which the dispensed volume of the liquid can be determined. [5]
A burette and Erlenmeyer flask (conical flask) being used for an acid–base titration. Titration (also known as titrimetry [1] and volumetric analysis) is a common laboratory method of quantitative chemical analysis to determine the concentration of an identified analyte (a substance to be analyzed).
Burette clamp is a scientific equipment which used specifically to hold and secure a burette on a stand, so that a burette is fixed and more convenient for the experiment. [1] Burette clamps can be made with many materials such as plastic and cast iron. However, an iron clamp with a rubber knob to hold the burette are usually more durable.
In chemistry, a retort stand, also called a clamp stand, [1] a ring stand, [2] or a support stand, [3] is a piece of scientific equipment intended to support other pieces of equipment and glassware — for instance, burettes, test tubes and flasks. [4] The typical ring stand consists of a heavy base and a vertical rod, both usually made of metal.
By means of a rubber tubing arrangement, the gas to be analyzed is drawn into the burette and flushed through several times. Using the stopcocks to isolate the absorption pipettes 100ml is typically withdrawn into the main burette for ease of calculation and the leveling flask is raised until the water is level between it and the burette.
A meniscus as seen in a burette of colored water. '20.00 mL' is the correct depth measurement. When reading a depth scale on the side of an instrument filled with liquid, such as a water level device, the meniscus must be taken into account in order to obtain an accurate measurement.
Laboratory test tube brushes: small sized brushes on the left, large sized brushes on the right. A test tube brush or spout brush is a brush used for cleaning test tubes and narrow mouth laboratory glassware, [1] such as graduated cylinders, burettes, and Erlenmeyer flasks.
