Chm138 Expt 1 Basic Lab Technique Calibrating A Pipette Experimentо

Chm138 Expt 1 Basic Lab Technique Calibrating A Pipette Transfer and mohr pipette are two types of common pipette usually found in the laboratory. a transfer pipette is calibrated to deliver only one volume, whereas a mohr pipette is graduated so that it can deliver any volume (usually to nearest tenth of a milliliter) up to maximum volume.

Determine the actual volume of the pipette from table 1. c. calibration of burette. 1. a 50 ml beaker is cleaned and dried and weighed accurately using balance analysis. the mass of the empty beaker is recorded. 2. a burette is cleaned and rinsed using distilled water and the burette is filled with distilled water to zero marks. (a) (1) deliver a precise volume of liquid at given temperature (2) use a pipette aid to fill a pipette (3) a label pipet is 2x more accurate than b (4) single band = not blow last drop (5) double band = blow out pipette (b) (1) td = to deliever (goes with time it takes to deliver e.g td 15 sec) (2) should not be blown empty (c) full label td 15 sec 20oc > time it takes to dispense is 15. This laboratory report summarizes an experiment on basic laboratory techniques conducted by muhammad mirza hizami bin rajiei and partners. the objectives were to learn qualitative and quantitative aspects of common laboratory equipment and expose students to factors affecting experimental accuracy. calibrations were performed on a volumetric flask, pipette, and burette. the results obtained.
