9:30-10:50 How to Essay How to cannulate yourself on dialysis Dialysis needles are large not to mention scary as hell. Imagine being stuck with a Capri Sun straw and it staying there for 4 hours. Fear of needles and pain is a reality for most people on dialysis‚ especially in the beginning. Some have true phobia‚ and require special techniques and interventions to self-cannulate. All patients‚ once they become familiar with dialysis‚ worry about who will put their needles in (and potentially

Diffusion Experiment: Osmosis in Sucrose Solutions Abstract We used dialysis tubing to simulate a semi-permeable membrane. Since molecules diffuse from their higher concentration to their lower concentration‚ water will move across the membrane in response to this concentration. While conducting this lab we were able to observe passive transport through diffusion and osmosis. Introduction Osmosis is a specialized case of diffusion that involves the passive transport of water. When

Materials Needed • Dialysis tubing • 2 pieces of thread • Funnel • Culture dish 8 test tubes • 2 disposable pipets • 100mL beaker • IKI dropper bottle • Silver nitrate dropper bottle • Barium chloride dropper bottle • Albustix • Clinistix Prodecure 1. A piece of dialysis tubing was procured and a knot was tied at one end. 2. A funnel was inserted into the open end of the dialysis tube and it was filled with a solution consisting of 1% starch

Lacrosse Monster #2 Dates performed: 10/10/11 and 10/11/11 Introduction: The purpose of the laboratory investigation was to observe the diffusion of water across a semi-permeable membrane. In this lab‚ dialysis tubing was used to represent the semi-permeable cell membrane. Three dialysis tubes were prepared with 5% sucrose solution and were soaked in solutions of different concentrations. The diffusion of water across a semi-permeable membrane is called osmosis. When water diffuses‚ the water

In response to D.W.‚ I would provide a comparison of plasmapheresis and dialysis‚ for that plasmapheresis is similar to dialysis‚ except that it instead removes the plasma which is

Molarities Through Dialysis Tubing (a Semi-Permeable Membrane) I. DESIGN A. PROBLEM/RESEARCH QUESTION 1. How does increasing molarity of sucrose affect osmosis through dialysis tubing? B. VARIABLES 1. The independent variable in this lab is the molarity of sucrose each dialysis bag is filled with. The time (30 minutes)‚ the temperature (23C) and the type of dialysis tubing used are all constants. 2. The dependent variable is the final mass of the dialysis bag.

This experiment was performed to measure the osmosis of small molecules through cellulose bag (has the same structure that plant cell does). This tubing acts as a selectively permeable membrane‚ allowing larger molecules to pass through‚ but slowly. Dialysis is the movement of a solute through a selectively permeable membrane. Purpose: To observe osmosis in a model membrane system. Hypothesis: If I immerse in the beaker containing water one bag with distilled water and one bag with 40% maltose

Introduction: In this lab i used glucose and starch to show if the cell membrane is permeable‚ impermeable‚ or selectively permeable to these substances. Dialysis tubing is a plastic like substance that has small pores in it. These pores allow certain chemicals to flow into and out of the cells. The size of the molecule determines what goes through the tubing. On of the materials that we will be using is glucose. glucose is a simple sugar that easily dissolves in water.
