Investigating the limits and capabilities of a measuring instrument. • Determining the accuracy of the actual volume of a volumetric pipette‚ volumetric flask & measuring cylinder. INTRODUCTION The purpose of this experiment is to investigate the measurement of the actual volume contents of volumetric glassware. If there is a slight variation in this instrument‚ it would cause systematic error and thus‚ the accuracy of results of an experiment or investigation would be affected. All volumetric glassware

Copper Sulphate Calibration Aim The objective of this experiment is to determine the unknown concentrations of solutions. Introduction With the use of absorption of light a spectrophotometer sends UV wavelengths through solutions to determine their concentrations. The light absorbed is measured as the atoms‚ molecules and ions absorb the wavelengths of light that the spectrophotometer gives off (Meah‚2013). The level of light transmitted defines the amount of light absorbed‚ for instance‚ the lower

Hello all‚ I went into the lab and none of the Ps had notes of calibrations occurring during or between any of the task. P 24‚ 54 and 71 all have massive decreases from baseline to both task. The real problem is that with out a note of when calibration occurred there are three logical explanation for this. First‚ that they ran across campus and were not actually at baseline when baseline measures where taken thus leading to the decrease when they do finally calm down. Secondly‚ the machine could

to determine if crossing the leg at the knee during blood pressure measurement has an effect on the patient’s blood pressure reading? In this experimental research the implementation of blood pressure (independent variable) will be monitored‚ and the acquisition about cross-leg (dependent variable) will be measured. The hypotheses are not clearly stated‚ although the study does state expectations according to their findings “blood pressure readings may be artificially high if measured while an individual

Calibration of Total Station As there is height transfer from Wong Yi Chau to Tai Tau Chau‚ reciprocal leveling is needed to minimize the effect of the atmosphere as well as the line of sight and curvature corrections. As a result‚ total station will be calibrated before performing reciprocal leveling. Line-of-sight error and V-Index are determined through calibration. Line-of-sight error and V-Index The line-of-sight error or collimation error (C) is the deviation from the perpendicular between

Lab 1: Calibration of Pipettes and Burettes Names TA Name‚ Thursday Lab: 1:40 P.M. - 4:10 P.M. Aim: This experiment sought to gather data regarding water volume gathered in glassware‚ then to statistically analyze the data‚ focusing on average and standard deviation‚ along with relative error gleaned from linear regression. Introduction: This experiment was divided into two parts. For part one of the experiment‚ 25 mL were transferred from a glass pipette to a tarred beaker and weighed

Theory The first experiment focused on the concept of errors and uncertainties that are obtained during measurements. For an experiment to be successful‚ especially those that involve measurements‚ the number of significant figures must be known. Significant figures are the digits required to express a measured quantity and thus reflect the accuracy of the measurement. Uncertainty is defined as the smallest increment that can be measured and is defined by the instrument used. An error is defined
