According to GCSE Science, a burette is calibrated to give readings that are accurate to 0.2 cubic centimeters. On the other hand, a pipette has a bulge in the middle, and is calibrated with a filling line that gives a precise volume of the substance it contains at the particular point. A clean volumetric pipette gives a reading to the precision of 0.01 milliliters, according to Green River Community College.Know More
A burette is a long tube made of glass that has a tap at its bottom end, GCSE Science explains. One type of burette is graduated along its length with marks that are 2 cubic centimeters apart. It has additional smaller marks in between that give it its level of accuracy, showing the total volume of a substance at each mark.
As Titrations explains, single volume pipettes belong to a category of volumetric glass that measure predetermined volumes of a solution. When a pipette is emptied, it delivers the exact volume of a solution it is designed to hold. The accuracy of a pipette is not affected by remnants of a substance on its walls and in the tip. The measuring tubes not only exhibit high levels of precision but also allow for repeatability of measurements.Learn more about Chem Lab
Some scales, such as bathroom scales, can be calibrated by simply using known weights and adjusting the scale reading to match the amount of the known weight. Digital scales can be calibrated using a weight and the scale's calibration mode.Full Answer >
A piece of pH indicator paper is used to gauge the acidity or alkalinity of a solution. Different types of pH indicator paper are used depending on the type of test and level of accuracy required, such as red or blue litmus paper.Full Answer >
Three crazy science experiments involved injecting an elephant with LSD, inducing clinical depression in monkeys and creating a mock prison environment. Each of these experiments was done in order to evaluate the behavioral characteristics of the subjects.Full Answer >
According to the North Carolina State University Chemistry Department, burette clamps are adjustable devices that secure burettes to laboratory ring stands. They are made from corrosion-resistant metals. Single burette clamps hold one burette, test tube or flask, and double clamps hold two. Double burette clamps also accommodate flasks and test tubes.Full Answer >
