1.0 Calibration of Volumetric Glassware 1.1 Introduction: Calibration is the process by which a stated measure such as the volume of a container is checked for accuracy. In general‚ measurements of mass can be determined more precisely and accurately than measurements of volume. Therefore‚ the mass of the liquid contained or dispensed by the glassware will be measured and the corresponding volume calculated using the density of the liquid. However‚ a relatively small change in temperature

OBJECTIVE To determine antiseptics evaluation by the filter paper disc method INTRODUCTION An antiseptic is a substance which inhibits the growth and development of microorganisms. Antiseptics are a diverse class of drugs which are applied to skin surfaces or mucous membranes for their anti-infective effects. This may be either bacteriocidal or bacteriostatic. Their uses include cleansing of skin and wound surfaces after injury‚ preparation of skin surfaces prior to injections or surgical procedures

Lab One: Laboratory Techniques and Measurements Abstract The Lab One was done on Laboratory Techniques and Measurements. The first experiment with my Lab partner; we got opportunity to experiment how to conduct measurements in length by using metric conversion. We started in cm units and changed into mm by x10‚ and moving decimal point x1 to right. To find in meter we moved from cm to meter two decimal points to the left or double check our self divided by 100 and all records in data

very precisely in quantitative laboratory work. The accuracy of the measurement the volumes is the degree of closeness of measurements of a quantity’s actual volumes while the precision of the volumes is the degree to which repeated measurements under unchanged conditions show the same results. Each of volumetric glassware is marked with its total volume‚ the notation of TD for ‘to deliver’ and TC for ‘to contain’ and also with the temperature at which the calibration applies. For greatest accuracy

Laboratory Long report. Electronic laboratory practice Abstract: The aim of this laboratory was to make us familiar with how to use the different types of electronic equipment and how to accurately use them to make measurements. The equipment used in this laboratory included: (i) the signal generator which was used to supply the power used in the various procedures‚ (ii) The oscilloscope which was used to view and record the waves produced from the AC currents and then make relevant calculations

2 MARKS & QUESTION- ANSWERS VI semester EI 336- Industrial Instrumentation -II PREPARED BY: M.V. MINI UNIT 1 1) Define Viscosity. It is a measure of fluidity of the system. Many fluids undergo continuous deformation with the application of shearing stress. 2) Define Newtonian fluids If the force flow relation is linear then the fluid is Newtonian . 3) Define Non Newtonian fluids If the force flow relation is non linear then the fluid is Newtonian . 4) Define Kinematic Viscosity

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
