P H A R M AC E U T I C A L application note Checking the accuracy of PERKIN-ELMER POLARIMETERS H. Stenz‚ Bodenseewerk Perkin-Elmer GmbH Abstract Quartz standards‚ sucrose solutions and optically active pure liquids are discussed as potential polarimetry standards. It is suggested to preferably use quartz standards for checking the accuracy of Perkin-Elmer polarimeters. Quartz standards are absolutely stable‚ have a high accuracy and are easy to use. For laboratories working in an environment

We labeled the test tubes with numbers one through five. The first test tube was our calibration tube‚ here we added one milliliter (mL) of buffer‚ four mL of distilled water and three drops of chloroplasts using pipets. After‚ we created the solution for the second‚ third‚ fourth and fifth test tubes by adding one mL of buffer‚ three mL of distilled water one mL of DPIP an 3 drops of chloroplasts. However

Abstract The experiment allowed students to explore different electrolytes and classify them into acids‚ bases and salts by using different indicators or by measuring the pH levels of each. The experiment also helped students classify different substances through their conductivity properties. The preparation of a 1 M stock solution from NaOH pellets diluted to a

Task 13 Problems encountered during the titration procedure and possible improvements that could lead to more reliable and valid outcomes. Throughout the titration experiment many problems were encountered as well as other errors were found that could have possibly occurred. These problems or errors will impact my % accuracy and therefore the quality of my results. Ideally no problems would occur‚ and I would be able to complete the experiment without any errors occurring which would therefore give

VINEGAR FERMENTATION VINEGAR BACKGROUND Vinegar is one of several fermented foods prepared and used by early man; and like others‚ wine‚ beer‚ bread‚ and certain foods from milk‚ its discovery predates the earliest historical records. The word “vinegar” is derived from two French words‚ “vin” and “aigre” meaning sour wine‚ but the term is now applied to the product of the acetous fermentation of ethanol from a number of sources. (ConnerHubert‚ 1976). Vinegar has played an important but little-emphasized
