Caroline O’Connor Lab 1: Lab Basics T.A. James Petersen 9/1/09 Chart and Scope 1.) Chart would be a better program because it has the ability to record continuously, and scroll back to previous times to view measurements. Scope, however, is more useful in comparing different pages of measurements. 2.) It is important to calibrate the transducer in order to be certain of a baseline and that the transducer is reading zero mV when it should. This will also ensure accurate measurements and results when the experiment begins, and will allow us to assume that the voltage reading relates to the physical unit being measured. Pipettes 3.) The first stop is used to measure the desired volume of solution being transferred. The

Unformatted text preview: distance to this first stop will change as volume changes. The second stop is used for complete discharge of the solution from the plastic tip. 4.) Inaccurate volume setting, not allowing the pipet tip to fill to final volume and thus producing bubbles, and inserting the pipet too deep into the solution as opposed to just below the surface. Microscopes 5.) The 10X objective gives the widest field of view. 6.) The 1000X objective requires the most light. 7.) Lens paper should always be used in order to prevent scratching of the lens....
