• 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 has marking on it. It is either being marked with TD or

Rev. 01/10 JEB GLASSWARE CALIBRATION 1. Objectives Verify the actual volume of liquid delivered by 2 different types of glassware devices. Evaluate which measurement method is better for different uses. 2. Techniques Buret use: Put the buret in a buret stand and approximately fill it with temperature-equilibrated water. Make sure that the tip of the buret is filled with water and that there are no air bubbles remaining in the buret tip or valve. Record the initial level – it does not need to

Experiment 1: Calibration of Volumetric Glassware Introduction: Volumetric glassware is used to accurately measure volumes. Despite all of the tools and instruments available for the use of measuring values of various data‚ it is impossible to measure the true value of anything. This experiment is intended to develop a person’s capacity to handle volumetric glassware. One must understand how to handle volumetric glassware to acquire the best possible data from the equipment used in lab. Although
