Even Q-tips that have only been used once may have dirt on them that could contaminate the methanol and cause scratches in subsequent objectives or oculars when they are cleaned. … WHEN LENS PAPER IS USED TO CLEAN

OBJECTIVES

OR OCULARS, USE A NEW, CLEAN SECTION OF THE PAPER EACH TIME YOU WIPE THE LENS SURFACE.

WHY IS lens paper used to clean the microscope?

why should

only lens paper

be used to

clean microscope lenses

? The glass on the

lens

is softer and will scratch easily. It allows the

lenses

to move independently. Once you have blown the

Why should you use lens paper?

Microscope Lens Paper is soft, dust-free paper that is used

for cleaning microscope slides and lenses without scratching the glass

.

Why must you use special lens paper to clean the eyepiece and the objectives?

Why is lens paper used to clean the microscope lenses?

It has extremely fine, soft fibers

. Other types of paper have coarser fibers that will gradually scratch the lenses causing them to become foggy and blurry.

When should the lenses be cleaned What is the correct way to clean them?

If the spot doesn’t move when you turn the

eyepiece lens and you see it at all powers

then the dirt is internal and you should probably have it cleaned by a professional. If you only see it at one power, the dirt is most likely on that particular objective lens. Sometimes all you need to do is blow off the residue.

Which lens must cleaned last and why?

If your

eyepiece lens

turns, turn it and see if the spot moves as well. If so, the dirt is on the eyepiece lens (if not, the dirt is internal and you should probably have it cleaned by a professional). If you only see it at one power, the dirt is most likely on that particular objective lens.

What is the safest solvent for cleaning an objective lens?


Acetone

is the safest solvent for cleaning an objective lens. Only lint-free, optically safe tissue should be used to wipe off microscope lens. … Once the focus is achieved at one magnification, a higher-power objective lens can be rotated into position without fear of striking the slide.

What is the advantage of using a wet mount?

Wet-mount Slides A wet-mount slide is when the sample is placed on the slide with a drop of water and covered with a coverslip, which holds it in place through surface tension. Advantages – This type of

slide preparation allows you to view microscopic living things without them drying out

.

What is the shortest objective lens?


A scanning objective lens that magnifies 4x

is the shortest objective and is useful for getting a general overview of a slide. A low-power objective lens magnifies 10x, but remember that it is coupled with an eyepiece lens, so the total magnification is 10x times the power of the eyepiece lens.

Should you focus by moving stage up or down?

Use the fine adjustment, if available, for fine focusing. If you have a microscope with a moving stage, then turn the coarse knob so

the stage moves downward or away from

the objective lens.

Which is the only objective lens that can come in contact with oil?

Before using immersion oil, make sure that your

100x objective lens

is made for use with immersion oil. Begin by focusing your sample using the 40x objective lens.

Which objective lens should be used first?

3. When focusing on a slide, ALWAYS start with

either the 4X or 10X objective

. Once you have the object in focus, then switch to the next higher power objective. Re-focus on the image and then switch to the next highest power.

Do you use alcohol to clean objective lens?

General procedure for cleaning an objective:


70% ethanol on cotton-tipped applicator

. … Distilled water (or breathe on the objective), wipe gently with lens paper.

What is in lens cleaning solution?

Lens cleaning solutions are generally

alcohol: methanol or similar

. (Methanol has a characteristic sweet smell). Most any alcohol will do, but be very careful if you get denatured alcohol that it doesn’t contain oils. A lot of times they’ll put oils in there to counteract the drying effect of alcohol on the skin.

What power objective should be in place when cleaning up?

ALWAYS use both hands when picking the microscope up and moving it from one place to another. 3. When focusing on a slide, ALWAYS start with either the

4X or 10X objective

. Once you have the object in focus, then switch to the next higher power objective.
