Using a sterile cotton swab, gently remove some of the exudate from the dog's ear. Place the exudate on a glass microscope slide and, pressing firmly, smear the exudate across the slide. Use an open flame source (hand-held flick-style cigarette lighters work well) and gently head the underside of the slide to attach the exudate to the slide. Stain the slide with standard Gram stain following the manufacturer's directions. Rinse the slide gentle with tap water and then place on the microscope for viewing.

What is cytospin?
A cytospin is a laboratory technique that involves depositing a cell suspension onto a slide, which is then spun at a high speed to spread the cells out evenly. This technique is commonly used in cytology to prepare samples for examination under a microscope. It helps separate cells from the surrounding fluid and allows for easier visualization and analysis.
How do you make a slide out of a pice of onion skin?
To make a slide out of an onion skin, prepare a clean glass microscope slide and cover slip. Gently peel a thin layer of the onion skin and carefully place it on the slide. Add a drop of water, then gently apply the cover slip over the onion skin to create a flat specimen. Carefully examine under a microscope.
If you prepare a wet mount slide and observe a large empty circle with dark edges you are most likely seeing an air bubble.?
True
What is a slide and cover slip and how is it used in science labs?
A slide is a small, usually rectangular piece of glass on which specimens can be mounted for microscopic examination. A cover slip is a small, thin piece of glass placed over the specimen on the slide to protect it and hold it in place. In science labs, slides and cover slips are used to prepare and view samples under a microscope for analysis and study.
What are the steps of the wet mount?
the five steps to making a wet mount slide is 1.use a flat glass slide to prepare a wt mount slide 2.suck up a few drops of water from your liquid specimen into a medicaine dropper 3.pick up the wet mount slide on the 2 outer sides of the slides 4.place the specimen your using into the water 5.place the top cover slips on the top of the water with the specimen in it (: (: (: (: (: (: (: (: (: (:

What happens when you prepare a smear from a agar plate or slant without first placing water on slide?
If you prepare a smear from an agar plate or slant without first placing water on the slide, the cells may not adhere well to the slide, leading to uneven distribution and difficulty in visualization. Adding a drop of water before preparing the smear helps the cells adhere to the slide and spread evenly for better microscopic examination.
How must samples be prepare for observation by electron microscope?
They must be preserved and dehydrated. Once this is accomplished, put the specimen onto a slide, and then the slide is ready to be viewed under the microscope.
How do you prepare a wet mount?
To prepare a wet mount, place a small drop of liquid or specimen on a slide. Then, gently lower a coverslip onto the drop at a slight angle to avoid trapping air bubbles. This creates a thin layer of liquid between the slide and coverslip for viewing under a microscope.
How do you prepare a heat fixed smear?
To prepare a heat-fixed smear, start by placing a small drop of the specimen (such as bacterial culture) on a clean glass slide. Using a sterile loop or stick, spread the drop evenly to create a thin film. Allow the smear to air dry completely, then pass the slide through a flame briefly to fix the cells to the slide, ensuring not to overheat and damage the sample. Once cooled, the slide is ready for staining and microscopic examination.

What is the best way to prepare a blood smear directly fron a skin puncture?
Wipe away the first drop of blood and then make the slide
If you prepare a wet mount slide and observe a large empty circle with dark edges you are most likely seeing an air bubble.?
True
How to do a wet mount slide preparation?
To prepare a wet mount slide, place a small drop of liquid or specimen in the center of a clean microscope slide. Gently lower a coverslip onto the drop at a 45-degree angle to avoid trapping air bubbles. View the specimen under a microscope on low power to observe.
How do you prepare specimen for stereo microscope?
To prepare a specimen for a stereo microscope, first place it on a clean glass slide. If needed, add a drop of water or mounting medium to help stabilize the specimen. Then cover the specimen with a coverslip, to protect it and ensure clearer imaging under the microscope. Finally, position the slide on the stage of the stereo microscope and adjust the lighting and focus for optimal viewing.
How do you prepare a wet mount slide for the microscope?
Take a clean slide (either depressed or flat) and add a drop of water using an eye dropper. Add the specimen and using the slip cover, touch the end of the slip cover to the water. Lay flat as smoothly as possible to omit bubbles from forming.
