Close view of burette with clamp. 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 ...
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.
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.
A utility clamp is a laboratory apparatus resembling a pair of scissors. The screw in the middle works as the wide adjustment of 2-prong. [1] It is composed of 3 parts: 2-prong adjust, metal rod, and clamp down (the clamp is attached to the ring stand for adjusting the height). This apparatus is connected to a ring stand or retort stand.
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 The gas is left to stand for about two minutes and then withdrawn, isolating the remaining gas via the stopcock arrangements.
The EVD is set to drain into a closed, graduated burette at a height corresponding to a particular pressure level, as prescribed by a healthcare professional, usually a neurosurgeon or neurointensivist. Leveling the EVD to a set pressure level is the basis for cerebrospinal fluid (CSF) drainage; hydrostatic pressure dictates CSF drainage. The ...
The use of a plastics policeman for raking the precipitate on the beaker wall. A policeman can be used for cleaning the inside of glassware, or for getting the last bit of precipitate out of a vessel.
A clamp is placed on the aorta between the cardioplegic catheter and aortic cannula, so that the flow of cardioplegic solution may be controlled by adjusting the clamp. Within minutes, the heart stops beating. [21] [22] Anastomosis (grafting)
