  • Glassware Calibration

    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

  • Common Laboratory Procedures

    Laboratory Experiment No. 1: Common Laboratory Procedures Objective In this experiment‚ the objectives were to use a balance and measure the volume of the liquids. Theory In the experiment‚ three calculations were used. These are the density‚ relative error and the standard deviation. Density is refers to the mass (m) per unit volume (V) of a material and is often represented by the symbols d or ρ‚ where d = m/V. The density of an object changes with pressure and temperature. Second‚
