Measuring Cylinders
Measuring cylinders are used for measuring volumes of mobile liquids. For viscous liquids or semisolids
a conical measure is easier to use. There are a variety of types and styles of measuring
cylinder.
For basic measurement of liquids in qualitative work a Class B cylinder is sufficient. For more
accurate measurement of liquid a Class A cylinder is appropriate. These are calibrated to half the
tolerance of Class B cylinders and each has a unique serial number for traceability. A certificate of
accuracy traceable to national standards can be provided if required. Class A cylinders are used in
analytical labs, quantative labs, and other controlled environments. They are not suitable for work
which requires accuracy of less than 1%. For this a bulb pipette (0.2%) or a gravimetric method
(0.0001%+) should be used.
Stoppered cylinders are used for making up solutions where it is important to homogenize the liquid
by shaking. They are also useful for measuring volatile
solvents where significant evaporation might occur if the liquid is exposed to air.
Class B Spout Cylinders
Manufactured in accordance with BS EN ISO 4788:2005 out of borosilicate or soda glass.
