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.
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.
Braun had been making videos, mainly tutorials, for fun since his teenage years, creating a YouTube channel on March 10, 2014. His first video was uploaded on March 24, 2014, and many of his early videos were recordings of his projects as a laboratory technician or at his parents' garage, with them later being filmed at his industrial-grade laboratory.

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.
Method of swirling an Erlenmeyer flask during titration. The slanted sides and narrow neck of this flask allow the contents of the flask to be mixed by swirling, without risk of spillage, making them suitable for titrations by placing it under the buret and adding solvent and the indicator in the Erlenmeyer flask.

Following a format similar to America's Funniest Home Videos/The Planet's Funniest Animals, the series showcases viral internet clips of funny animal moments as well as celebrity guests, their pets, and panelists to commentate on the clips.
They come in a variety of sizes, and are used much like a burette, in that the volume is found by calculating the difference of the liquid level before and after. The last graduation mark is some distance from the tip, to avoid errors in measuring the narrower volume of the nozzle. [ 3 ]
