steps for making a microscope slide

Prepare a wet mount slide. Youll need to follow these instructions when developing your dry-mount slides:Pick a neat and clean glass slide or clean it using this methodPlace your dry specimen in the middle of the slideCover the specimen with a coverslip so it will never moveCarefully place the slide on the center of the stage of the microscopeSet the resolution power on which you want to observe the sampleMore items Use the right kind of slide mount. If your slide is dirty or smudged, you wont be able to effectivel Choose the right stains to bring out the desired features. Use a toothpick or forceps to gather non-liquid subject material.

More items Put a drop of stain on an outer edge of your cover slide. Using tweezers, place the onion skin onto the drop of water on the slide. * Heat Fixing the Bacterial Sample * Before staining, the sample must be heat fixed. 5. * Place a drop of water into the wax circle that has been created on the slide.

Place a small drop of a liquid sample onto the slide.Take a second clean slide. Hold it at an angle to the first slide. Use the edge of this slide to touch the drop. At this point, either allow the slide to dry so that it can be stained or else place a coverslip on top of the smear. Dont apply pressure; Place the slide on the stage of the microscope and observe under different resolution power; Advantages. Most microscope slides are flat on top and bottom and rectangular in shape. - as far as it will go. Just place a drop of the liquid material on the slide. 3. Place the slide on the Mechanical stage and fasten it with the stage clips. Add glycerine to the mount. 2. 2. Pipette a little bit of the Euglena Gracilis water from the jar. Stick the coverslip onto the center of the microscope slide. Place a piece of napkin or paper towel against the opposite side of your cover slip, right up against the edge. Home; Animal; Education. Select a clean slide. The method of making microscope slide system 10 includes as a first step the depositing of a layer of fluorocarbon 14 on upper surface 16 of optically clear glass slide 12. You are bidding all the slides photographed. Collect a drop of stain with an eye dropper or pipette. Transfer materials to the water or polish drop by touching the toothpick or forceps to the mountant. This is to hold the onion skin and to keep it from drying out. Remove the slide turn the scope to low power turn off the light. Using the pipette, draw a few drops of the liquid you want to examine. 3. There are three types of mounts that you can choose from when making microscopy slides. Position sample on liquid, using tweezers. If necessary, gently move the toothpick or forceps to dislodge materials. What are the 5 steps for creating a wet mount slide? There are some microorganisms that live in water and require water for survival. Place the slide on the stage and move it so that a promising area is over the light source. There are no cracks or chips to the glass, but they do have the scuffs, marks and scratches that you expect from a well used items of this Culture from solid media: Using a sterile pipette, add one drop of sterile saline or sterile water to the center of the microscope slide.

Place the coverslip at a 45-degree angle with one edge touching the water and let go. Your slide is ready to be viewed. Steps to prepare Smear Slides. Choose the kind of slide that fits your special microscope equipment and the purpose of your examination. These are dry mount, wet mount, and prepared mount. * Using a sterilized and cooled inoculation loop, obtain a very small sample of a bacterial colony. Remove the slide turn the scope to low power turn off the light. a. Each mount has its own pluses and minuses. Raise the Condenser upward toward the slide GENTLY! Under a wet mount slide the bacteria can more easily move and their interactions with the environment can be more easily observed. To prepare the They are all paper covered and have the subject matter hand written or printed to one side. Step by Step How to Use a Compound Microscope Turn the Objective Lenses so that the longest lens (the lowest power one) is in viewing position. IMG 1 show the design of my case for the microscope. The first step in making your own slides is to choose the type of mount you want. Move the low-power (10) objective lens close to the slide. 4. Microscope slide preparation using concavity slide 1.

What should be done whenever you are finished using a microscope? See to make sure the entire area under the coverslip is covered with water. Focusing a light microscope involves several steps. These 22 slides are in "as found" condition. 4. Viewers will learn how to prepare a microscope slide properly. Lower the Mechanical stage to make more room if needed. Take a piece from on of the sections and peel off a small, thin piece of the onion epidermis, or skin. * Gently mix the bacteria into the water drop. In these cases, your only practical option is to use a wet mound slide. 7. Lower the cover slowly, avoiding air bubbles. Gently squeeze three or four drops of liquid, using the pipette, into the slides concave depression, or well. Make sure that the lowest power lens is in place before proceeding. Wet Mount: Place a drop of fluid in the center of the slide. If the mount is not correctly placed observation under microscope becomes difficult. Insert a drop of pipette water into the edge of the coverslip without tape. Dilute 1 mL of sperm in 1X PBS (1:10) and centrifuge for 5 min at 500,. Be sure the oculars are clean - USE LENS PAPER ONLY! Now trace the marks on the glass of transparent plastic. Set condenser diaphragm at 30 to start out. Easily observe blood cells and bacterial growth. With the paper still on top, the slide is held over a bunsen burner for five minutes. Measure all the four sides in my case it's a square so i have to measure only one side of it. Use an effective mounting medium. Raise the lens with the coarse adjustment knob until the specimen comes into focus. The paper is removed, and the slide is carefully rinsed with water. The second stain is Mix evenly to make a thin smear. To get the highest quality slides, you must: Choose the highest quality glass for your slides and cover slips.
