how do you prepare a wet mount slide

How to Make a Wet Mount Slide

1. Use a flat glass slide to prepare a wet mount. The slide should be clean and free of dust or other fine particles.
2. Suck up a few drops of your liquid specimen into a medicine dropper.
3. Pick up a flat glass slide with one hand, grasping it by the outer edges.
4. Place one drop of the liquid specimen in the medicine dropper on top of the slide. Make sure the drop goes on the center portion of the slide.
5. Put down the medicine dropper. Do not tilt the slide in your other hand while you are doing this.

What is a wet mount compared to a prepared slide?

What is the difference between a wet mount and a dry mount preparation? Dry mount means placing sample directly on slide without putting water. Wet mount means placing a sample in drop of water on slide and then covering it with cover slip.

How do you set up a temporary wet mount 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.

How to make a temporary wet mount slide?

• Place a small drop of the specimen fluid that contains the specimen onto the middle of the slide.
• Carefully hold the slide by the edges, or you can use the tweezers if you’re more comfortable that way. ...

Making slidesPeel a thin, transparent layer of epidermal cells from the inside of an onion.Place cells on a microscope slide.Add a drop of water or iodine (a chemical stain).Lower a coverslip onto the onion cells using forceps or a mounted needle. This needs to be done gently to prevent trapping air bubbles.

Why is preparing wet mount an important skill to gain?

Wet mounts are commonly used in the science of Biology. This is an important skill to develop in order to be able to study specimens with a Microscope.

How do you get water bubbles out of a wet mount?

Apply a vacuum: This speeds up the movement of the fixing solution or water into the specimen. Dehydrate the specimen: Place the specimen into alcohol. Some specimens will shrink and lose water and air. By placing the specimen into water again, the specimen will take up the water.

Can I make my own microscope slides?

You can make simple homemade slides using Scotch tape, and the materials listed below. Some objects, such as a dollar bill, can be viewed by placing directly onto the stage, and holding in place using stage clips. Experiment for yourself to see how the materials below can be viewed with your compound microscope.

When preparing a wet mount what is mixed with the sample to be tested?

A vaginal wet mount preparation is a test where a sample of vaginal discharge is observed by wet mount microscopy. The swab collected sample is placed on a clean glass slide and mixed with either 0.9% saline or 10% potassium hydroxide (KOH).

What is a wet mound slide?

A wet mound slide is a slide that is prepared with some type of liquid placed at the center of the slide that will serve as the medium through which the specimen will move or interact with during microscopic observation.

Why does my wet mount slide have bubbles?

Air bubbles can form if your slide coverslip closes too rapidly causing air to be trapped under the coverslip or a displacement in the water that is rapidly filled by air.

Why is it important to lower the other side of the coverslip slowly and gently?

It is important to lower the other side of the coverslip slowly and gently because is you just let the coverslip drop onto the water droplet you will get air bubbles. Air bubbles will make viewing your specimen much more difficult.

How to prepare a vaseline mount?

To prepare a Vaseline mount, use the Q-tip and apply some Vaseline only to the outer edge of the slide coverslip. Then once you have the outer edge coated you can lower the slide coverslip just like you would on a standard wet mount (as described above).

Why does my coverslip float?

Floating Coverslip. In some cases, you may find that if you add too much water your coverslip will float after you place it over the water droplet. This can cause you slide coverslip to move to one side or the other of the slide and can also disrupt your sample in some cases.

What to do if you add too much water to a slideslip?

If you have added too much water and the coverslip has floated or if water has bled out to the edges of the slide you can use the edge of the paper towel and place it next to the edge of the coverslip and just let the paper towel extract some of the excess water. Now you are ready to take your wet mount slide and place it on the microscope stage and start observing your specimen.

How to use Q tip on microscope?

The first step is to use the Q-tip to swab your sample and apply it to the center of the microscope slide. If your specimen is a littler larger you can use tweezers or whatever tool that will help you place the specimen in the center of the slide without damaging it, killing, it or contaminating it. If your sample is some microorganism in the water, you can skip this step.

What is wet mount?

Wet mount technique is used for preparing eukaryotic cells, such as the cells of plants and animals for the microscope. In order to view bacteria ( prokayotes ), which are much smaller than plant and animal cells, a different specimen preparation technique is used called a bacterial smear.

How to collect liquid specimens?

Use a pipette to collect a small amount of the liquid specimen. Take a piece of microscope slide, and place a drop of the specimen on to the slide. Using a second piece of a glass slide, smear the specimen around the slide by dragging the smearing slide across the first.

What type of microscope does a specimen have to be prepared before it can be viewed?

For many types of microscopes, especially light or bright field microscopes, some form of specimen sample preparation must be done before the specimen can be viewed under the microscope. Take for example a compound light microscope. It makes use of microscope slides to mount the specimen on, before loading it onto the microscope for viewing.

What is a flat slide?
