Graduated cylinders do not have the accuracy and precision of pipets. Glass transfer pipets are more precise than measuring (Mohr) pipets. Volumetric flasks are more accurate and precise than Erlenmeyer flasks, graduated cylinders and beakers.

WebThe standard deviation is related to the precision of the measurement. If a pipet is supposed to dispense 10 mL and it actually dispenses 15, 16, and 15 mL then it has high precision (because the numbers are close.) Its accuracy is way off because the average of 15.3 mL is half of an order of magnitude different than 10. WebIn these two volumes I have tried to outline our present knowledge concerning the chemistry of melts in metallurgy. Had I done this twenty years ago, it might have been possible to include almost all the chemical knowledge then available. But today, thanks to the difficult work done by many metallurgists and chemists, that is no longer the case. I have … WebMar 4, 2024 · (UNCG General Chemistry) What is the most accurate type of glassware?
