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
To read the volume accurately, the observation must be at an eye level and read at the bottom of a meniscus of the liquid level. [7] The main reason as to why the reading of the volume is done via meniscus is due to the nature of the liquid in a closed surrounded space. By nature, liquid in the cylinder is attracted to the wall around it ...
The solution will form a meniscus, whose position is read according to the scale printed on the pipette. For high viscosity liquids, the volume is measured by looking at the upper meniscus. For low viscosity liquids, the volume is measured by looking at the lower meniscus. [12]
A Mohr pipette, also known as a graduated pipette, is a type of pipette used to measure the volume of the liquid dispensed, although not as accurately as a volumetric pipette. [1]
In practice the contact angle is rarely measured; instead, either literature values are used or complete wetting (=) is assumed. [ 2 ] In general, surface tension may be measured with high sensitivity using very thin plates ranging in thickness from 0.1 to 0.002 mm.
Meniscus may refer to: Meniscus (anatomy) , crescent-shaped fibrocartilaginous structure that partly divides a joint cavity Meniscus (liquid) , a curve in the upper surface of liquid contained in an object
Sample preparation for mass spectrometry is used for the optimization of a sample for analysis in a mass spectrometer (MS). Each ionization method has certain factors that must be considered for that method to be successful, such as volume, concentration , sample phase, and composition of the analyte solution.
A Stiff diagram, or Stiff pattern, is a graphical representation of chemical analyses, first developed by H.A. Stiff in 1951.It is widely used by hydrogeologists and geochemists to display the major ion composition of a water sample.
