Uncertainty andEquipment Error by Chris Paine Bioknowledgy 2. Absolute uncertainty and recording data When you record measurements you should also record the (absolute) uncertainty associated with the measurement The uncertainty reflects greatest precision, i.e. the smallest unit to which a measurement can be made. This method of quoting uncertainty is called least count 3. Absolute uncertainty and recording data For example

Buffer Solutions by R.J. Beynon, J.S. Easterby Complete list of books Titration » Burette, pipette, flask - volumetric glassware During titration experiments you will be using several types of volumetric glass. They all are designed to help measure volume of a liquid. Some measuring cylinder types of the volumetric glass can be used only to measure predefined volume of solution. These are volumetric flasks and single volume pipettes. They are characterised by a a high accuracy and repeatability of measurements. Flasks are designed to contain (TC, sometimes marked as IN) known volume of the solution, while pipettes are generally designed to cm3 measuring cylinder deliver (TD, sometimes marked as EX) known volume (although in some rare cases they can be designed to contain). This is an important distinction - when you empty pipette you deliver exactly required volume and you dont have to worry about the solution that is left on the pipette walls and in pipette tip. At the same time you will never know how much solution was in the pipette. On the contrary, volumetric flask is known to contain required volume, but if you will pour the solution to some other flask you will never know how much of the solution was transferred. Both kinds of glass were designed this way as they serve different purposes. Volumetric flask is used to dilute original sample to known volume, so it is paramount that it contains exact volume. Pipette is used to transfer the solution, so it is important that it delivers known volume. Note, that volumetric pipettes are designed in such a way that after a
