Compared to a volumetric pipette, a burette has similar precision if used to its full capacity, but as it is usually used to deliver less than its full capacity, a burette is slightly less precise than a pipette. Which is more accurate burette or volumetric flask? Volumetric Glassware...
Which instrument(s) has (have) the greatest precision for measuring volume: 10 mL graduated cylinder, 50 mL graduated cylinder, 50 mL burette, 10 mL graduated transfer pipette, and 10 mL volumetric pi Consider drop counts of 20 drops per 1.0...
Label a series of volumetric flasks or microtubes. A minimum of five standards are recommended for a good calibration curve. Pipette the required volume of the standard into the first flask or microtube. Change the pipette tip, add the required volume of solvent to the same flask or microtube...
A 0.5118 g sample of CaCO_3 is dissolved in concentrated HCl (12 M) the solution was diluted to 250 mL in a volumetric flask to obtain a solution for standardizing the EDTA titrant. How much molarity of the Ca^{2+} in the 250 mL...
Add 1 ml of 100 mM EDTA. Bring the volume up to 100 ml with a volumetric flask and store at 2-8°C. Ideally, protease and phosphatase inhibitors should be added on the day of use (100 μl each of aprotinin, leupeptin, and pepstatin; 500 μl each of PMSF, Na3VO4, and NaF). ...
