Certain unknown wire essay

Samples that melted were recorded.

What information will the Enterotube II Test give us? Push the wire back through the Enterotube so that the 12 chambers are re-inoculated.

Inoculate the Enterotube with the bacterial culture by drawing, and at the same time rotating, the wire through the 12 compartments. For the melting tests, approximately polymer beads were placed in an aluminum weigh boat.

Use color where appropriate. The interpretation is done by determining a five-digit code from the results and then consulting a coding manual. Dilute liquid no clumping. It is ordinarily rigid, but can be made flexible with certain additives called plasticizers. What does agglutination mean?

Bulky or large side groups can impede rotation, thus raising the melting temperature Callister, Polyethylene, another polymer in table 1 is chemically resistant, electrically insulating, tough, and has a low coefficient of friction, yet has low strength and poor resistance to weathering.

Procedure a Place a drop of the Latex Control liquid in one of the circles on the test card. At low molecular weights, polymers with longer chains have higher melting temperatures that those with shorter chains.

Microbiology Unknown

The boat was labeled and placed in a Blue Heating Oven. The Latex Control liquid will have the liquid contain the latex beads with no antibodies attached. Touch a well-isolated colony from an agar plate with the tip of the wire. Remove the caps from both ends of the Enterotube.

Branching induces defects into the crystalline structure of a polymer, thus lowering the melting temperature Callister, Agarplate Read the Latex Agglutination Test information provided and answer the following: It is also chemically inert and relatively inexpensive, but has a poor resistance to UV light.

Polypropylene is a widely used polymer, best known for its resistance to heat distortion, excellent electrical properties and fatigue strength. A polymer with a high degree of branching generally has a lower melting temperature than a similar molecular weight polymer with a low degree of branching.

Polycarbonates can be found in safety helmets, lenses, light globes, and as a base for photographic film Callister, The Enterotube II System The basic philosophy of the Enterotube II System is the speed, ease and low cost in the identification of gram negative, glucose fermenting, oxidase-negative Enterobacteriaceae.

The tip of the wire is sterile and does not need to be flamed. What will a negative result look like?

The end of the needle can touch an isolated bacterial colony and then in one movement can be drawn through the 12 compartments so that every compartment is inoculated. Since we are in microbiology we are looking for the clumping of Epitopes found on the surface of Antigen that will bind to specific Antibody that were made by Immune system B cells.Free Essay: Percent Copper and Formula of a Copper Compound Sofia Economides Date Preformed: 3/19/ Date Submitted: 3/26/ Lab Partners: Anita Smith.
