Microscopic examination
The analysis of minute organisms, cellular organization of any biological structure, and composition of body fluids with the help of a microscope is known as microscopic examination. The magnification of specimens or samples under study helps in attaining a clearer picture of it.
Gram Staining
Named after Hans Christian Gram, a Danish bacteriologist, Gram stain is one of the most powerful staining techniques within microbiology. This technique was introduced in 1882 to identify pneumonia-causing organisms. The Gram staining technique uses crystal violet or methylene blue as primary staining colors to distinguish gram-positive from gram-negative organisms. Under a microscope, the gram-positive organisms appear purple-brown, retaining the primary color. Gram-negative organisms appear pink or red as they do not acquire the color of the primary stain.
List 6 ways on the proper handling/manipulation of the microscope.
Step by step
Solved in 2 steps
- List the steps to properly store/focus your microscope.3. Please number these steps, in the order they should be completed when using a microscope. Remove specimen, lower stage, wrap cord, and return covered microscope to numbered shelf. Move to other objective lenses to increase magnification. Rotate lowest-magnification objective lens into position (probably 4x or 10x). Clean all lenses with lens paper. Place specimen on stage. Adjust chair to a comfortable height. Use coarse focus knob to adjust stage until an image is visible. Be careful to use only the fine focus knob with the longest objective lenses.A. Purpose: Figure 1 B. Materials: Microscope Magazine Slides and cover slips Paper towels Pipette Scissors C. Procedure: 1. Careful carry a microscope to your lab area. Make sure to hold it with one hand under the base and one hand on the arm as shown in Figure 1. 2. Plug the microscope in and turn it on. Take a moment to look at all the parts of the microscope. Then look at your ocular lens. What is the magnification of the ocular lens (eye piece)? Figure 2 3. Fill in the chart to show the total magnification for each objective lens. Magnification of Ocular Lens Magnification of Objective Lens Objective Lens Total Magnification Low Power Medium Power High Power
- PROCEDURE: 1. Set two pencils down parallel from each other. Make them about 2-3 inches apart as the length of your slides to keep things easy. 2. Stick a long piece of tape over the two pencils and to the table on either side of the pencils to hold the tape tightly between the two pencils like a bridge. 3. Don’t touch the sticky side of the tape or you will ruin the microscope. Drop a small drop of water onto the top of the tape using the pipette or medicine dropper. 4. Make 3-4 lines of tape and add a different-sized drop to each one. This will help determine what size of water droplet produces the biggest magnification. 5. Prepare a rectangular shape of plastic cover. Put a small slice of onion. Slide the rectangular shape of the plastic cover with the small slice of onion under the pieces of tape and observe the size of the onion on different droplets. Write your observations on the table below. No. of drops Observation1. Match: Read about each microscope part. Match the description to the part on the diagram. Stage: Platform where a slide is placed. Eye piece: Lens at the top of the microscope that the user looks through. This lens most commonly magnifies a sample by 10x. Coarse focus knob: Large knob that moves the stage up and down to focus the sample. Fine focus knob: Small knob that moves the stage over a short distance to refine the focus. Objective lens: A second lens that further magnifies the sample. Microscopes usually have several objective lenses with different magnifications. Slide: A rectanqular piece of glass upon which a sample is mounted for viewing under a microscope.You have placed a microscope slide in a microscope and want to view it at with the 10X objective lens. List the steps that are necessary to set up and focus the microscope properly using the 10X objective lens.

Projection microscopeShown below are several micrographs (images from microscopes) that were taken using different microscopy techniques. Write down what method of microscopy was used and why you thought so. Choices for microscopy techniques are: Transmitted Light Microscopy (techniques of brightfield, phase-contrast, darkfield, DIC all fall under this), Fluorescence Microscopy, Scanning Electron Microscopy, and Transmission Electron Microscopy.Using the provided materials and the microscope itself, review the parts of the microscope including the name, where it is located, its function and the appropriate times to use. Record your observations and notes as vou will require this information when writing yourlab report
