Introduction: The purpose of this lab report is it demonstrate Materials and Methods: This lab was performed as outlined in the Bio 130L Lab Manual Fall 2008 on pages 47 to 52. (University of Waterloo, 2008) Results and Observations: Table 1: This table describes the weight of the dialysis bag at five minute intervals, starting from zero minutes to forty minutes.
