The usual practice of repairing a broken slide is to use Scotch Tape; but often fine splintering with loss of some part of the slide results in loose-jointed coherence, making impossible placing the slide on the stage of a microscope or filing it in a slide box with compartments.
What should you do if a microscope slide breaks?
If a slide or cover glass is broken, dispose of it and replace it immediately to prevent anyone from being cut. The adhesive used to attach a cover glass to a slide is applied as a liquid. As the liquid dries, it only hardens around the edges of the cover glass.

How do you seal a microscope slide?
Place the coverslip with the sample pointing towards the slide onto the slide. Dip the brush of the nail polish into the bottle and then dry it a little bit by squeezing gently against the inner side of the bottle neck. Place four small dots of nail polish first on the corners of the coverslip to fix it a little bit.
Why do microscope slides stick together?
The adhesive force acting between the glass and water is responsible for sticking up of the slides. Greater the surface area larger will be this force. It is the adhesive force that creates surface tension. … The water trapped between the slides has a lower pressure as compared to the atmospheric pressure.What is a depression slide?
Definition of depression slide : a glass slide that has a concavity in one surface over which a cover glass can be placed and that is used in biology for hanging-drop cultures and for the microscopic study of small specimens.

- Coverslips are fragile – handle with care.
- Coverslips should be clean and fingerprint free. …
- Both glass slides and coverslips should be held by their edges.
How do you sterilize slides?
- degrease and clean slides in Windex by placing n coplin jars.
- transfer to 95% isoporpanol (or ethanol) in coplin jars and then wipe clean. …
- rinse in white vinegar – the acid etches the glass surface slightly – wipe dry.

How do you make a grease free slide?
Grease or oil from the fingers on the slides is removed by washing the slides with soap and water. Wipe the slides with spirit or alcohol. After cleaning, dry the slides and place them on laboratory towels until ready for use.
Why do you clean and dry the slide and cover slip?
It is a good idea to clean twice the amount of coverslips as slides because they are easily broken. 3. Fill both slide and coverslip holders with 2% micro90 solution so that slides are covered.
How do you get rid of air bubbles on a microscope slide?
Apply a vacuum: You can remove air bubbles by placing the slide into a vacuum. THe bubbles will expand and move out beneath the cover glass. Dehydrate the specimen: Place the specimen into alcohol. Some specimens will shrink and lose water and air.
What holds the slide in place?
Stage clips hold the slides in place.
Can you put sperm under a microscope?
The air-fixed, stained spermatozoa are observed under a bright-light microscope at 400x or 1000x magnification. Their viability and mor- phology can be analysed at the same time. Those appearing red-pink in colour have a damaged membrane whereas white sperm are viable, as in Photo 2.
Can you view sperm under a microscope?
A semen microscope or sperm microscope is used to identify and count sperm. … You can view sperm at 400x magnification. You do NOT want a microscope that advertises anything above 1000x, it is just empty magnification and is unnecessary.
How do you smear sperm?
To examine sperm morphology, prepare at least two smears after the semen has liquified (>30 minutes). The specimen should be thoroughly mixed before pipetting the aliquot onto the slide and then mixed again before preparing the second slide.
What is the use of cover slip?
The main function of the cover slip is to keep solid specimens pressed flat, and liquid samples shaped into a flat layer of even thickness. This is necessary because high-resolution microscopes have a very narrow region within which they focus.
What is a biological microscope?
A biological microscope is generally a type of optical microscope that is primarily designed to observe cells, tissues, and other biological specimens. Multiple objective lenses can be attached, which gives these microscopes a magnification that can range anywhere from 10x – 1,000x or more.
What is depression in simple words?
Depression (major depressive disorder) is a common and serious medical illness that negatively affects how you feel, the way you think and how you act. Fortunately, it is also treatable. Depression causes feelings of sadness and/or a loss of interest in activities you once enjoyed.

What happens when you put water on a glass slide?
Adhesion between water and glass leads to capillary rise in a glass tube. The cohesive force of water molecules is responsible for the phenomenon of surface tension. Close-up of projected image of needle floating on water surface. … As a result, water molecules are drawn toward the center of the liquid mass.
What is the proper way of carrying a microscope?
Important general rules: Always carry the microscope with 2 hands—place one hand on the microscope arm and the other hand under the microscope base.
