the following items are needed: Dialysis tubing‚ IKI solution‚ 15% glucose/1% starch solution‚ distilled water‚ balance‚ sucrose solutions (0.2M‚ 0.4M‚ 0.6M‚ 0.8M‚ 1.0M)‚ glucose test tape‚ beakers (multiple)‚ petri dish. In the experiment‚ one will measure diffusion through a selectively permeable membrane (dialysis tubing). A 30 cm by 2.5 cm piece of dialysis tubing that has been soaked in water is acquired and made into a bag by tying one end of the dialysis tubing and opening the other end.

For organizations like Fresenius Medical Care‚ a worldwide company‚ the awareness of external environmental factors is vital to maintain competitive on the dialysis industry. Even though there are multiple external factors to analyze‚ in recent years the government works as an element of change on the medical industry with the biggest health reform in United States history.

Black Chem 4135.001 Abstract: Like the previous experiments‚ the ultimate goal of this lab was to purify the enzyme sample. However‚ this is the last lab for purification and high level techniques of purification were employed to achieve this. Dialysis was used first‚ lowering the small-molecule concentration within the sample. Finally Affinity Chromatography on a Cibacron blue Sepharose stationary phase. Using BSA‚ which is analogous for BCA assays‚ a standardization was created to understand

A strength is that the experiment was quick and easy. Ways to improve the experiment A in which the experiment could be improved is that the dialysis tubing could have came already cut into the 25cm. Conclusion In conclusion to this‚ the results support the hypothesis. Which means as the percentage of sucrose increase‚ the weight of the dialysis bag had also increased.

concentrations of sucrose on the mass of a potato cell. Results for Part One suggested that the molecular weight of albumin and starch was too large to pass through the dialysis tube‚ but glucose and sodium sulfate molecules were small enough to pass through the dialysis tube. Also‚ a decrease in water weight occurred due the dialysis tube being placed in a hypertonic solution. Results for Par Two showed the potato cell having a molar concentration of 0.2734‚ which caused sucrose concentrations above
