What are some limitations of a phenol coefficient test?
Your results might be different then these but I hope this will give you an idea for an answera. In our lab we observed growth in all of the test tubes. Originally we had hypothesized that the tubes with higher concentrations of disinfectant would inhibit the growth of the inoculated organism. This experiment allows us to conclude that the disinfectant is not very efficient. Although we were able to come to a conclusion, our results are limited to the organisms that we used to inoculate the test tubes. Different organisms might be more resistant to the disinfectant. A conclusion that the disinfectant we used is inefficient with all bacteria cannot be made.
What is a test tube used for?
Test tubes are widely used by chemists to hold, mix, or heat small quantities of solid or liquid chemicals, especially for qualitative experiments and assays. Their round bottom and straight sides minimize mass loss when pouring, make them easier to clean, and allow convenient monitoring of the contents. The long, narrow neck slows down the spreading of vapors and gases to the environment. A test tube filled with water and upturned into a water-filled beaker is often used to capture gases, e.g. in electrolysis demonstrations. Culture tubes are often used in Biology for handling and culturing all kinds of live organisms, such as molds, bacteria, seedlings, plant cuttings, etc.; and in medicine and forensics to store samples of blood or other fluids. A test tube with a stopper is often used for temporary storage of chemical or biological samples. Test tubes are usually held in special-purpose racks, clamps, or tongs. Some racks for culture tubes are designed to hold the tubes in a nearly horizontal position, so as to maximize the surface of the culture medium inside. Test tubes are sometimes put to casual uses outside of lab environments, e.g. as flower vases or containers for spices.
