A burette (also spelled as buret) [1] is a graduated glass tube with a tap at one end, for delivering known volumes of a liquid, especially in titrations. It is a long, graduated glass tube, with a stopcock at its lower end and a tapered capillary tube at the stopcock's outlet.
Burettes are similar to graduated cylinders but have a valve at the end used to disperse precise amounts of liquid reagents often for titrations. [17] Glass pipettes are used to transfer precise quantities of fluids. Glass Ebulliometers are used to accurately measure the boiling point of liquids. [18] Other examples of glassware includes:
Bourette is a silk fabric with bumps often blended with other yarns made of Bourette fibers. The name "Bourette" is from its constituting fiber.It has a rough surface incorporating multicolored threads and knots of spun silk.
Pipetting syringes are hand-held devices that combine the functions of volumetric (bulb) pipettes, graduated pipettes, and burettes. They are calibrated to ISO volumetric A grade standards. A glass or plastic pipette tube is used with a thumb-operated piston and PTFE seal which slides within the pipette in a positive displacement operation ...
The gas is then passed into the Potassium Hydroxide (caustic potash) burette by opening the stop cock and lifting the leveling flask. This siphons water into the burette which pushes the gas into the absorption vessel. The gas is left to stand for about two minutes and then withdrawn, isolating the remaining gas via the stopcock arrangements.
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.
Several sizes of volumetric pipette. A volumetric pipette, bulb pipette, or belly pipette [1] allows extremely accurate measurement (to four significant figures) of the volume of a solution. [2]
