slide is in the experiment used to place the experimental materials of glass, oblong, thick, translucent better; the coverslip is covered in the material, liquid and the objective lens to avoid contact, in order to avoid the pollution of the lens, is square, thin, light transmission is good.

.

Slide is microscope was used to observe the things to put things a sheet of glass, and coverslips placed on it, used to observe the cell.

usage

1, smear is the material evenly coated on glass slides and a preparation method.
smear material unicellular organisms, small algae, blood, bacteria culture medium, plant of loose connective tissue, testis, anther etc..
Should pay attention to smear:
(1) slides must be clean.
(2) slides to flat.
(3) coating shall be uniform. Apply liquid drops in the slide centre right, with a dissecting blade or toothpick evenly.
(4) to a thin coating. With another carrier slide pushing piece, along the drop a smearing liquid carrier glass one-sided (should second slide angle is 30 degrees to 45 degrees) from right to left gently push, painted a uniform thin layer.
(5) fixed. For the use of fixed available chemical stationary agent or drying method (bacteria) fixed.
(6) staining. Using methylene blue bacteria, blood wright'dye. Dyeing liquid to cover all coated surface.
(7) flushing. Dry or dry with absorbent paper.
(8) mounting. The long-term preservation of Canada with balata.
2, squash method the biological materials placed in a slide and a cover sheet between, to exert a certain pressure, tissue pressure powder a kinds of production methods.
Span; style= font-size:18pt "< or on the platform. When the water content should be appropriate, which happens to be covered with coverslip for.
(2) should be material with dissecting needle or tweezers not to overlap, flattening in the same plane.
(3) on the coverslip, slowly from one side cover on the water, to prevent the emergence of the bubble.
(4) staining, a drop of staining droplets on one side of the glass, with absorbent paper from the other side of the draw, coverslips were uniformly colored. After coloring, in the same way, a drop of water, the dyeing liquid is sucked out, under the microscope.
4, from a biological slice is cut into the sheet of glass specimen.
because requirements are different, use the blade by hand sectioning, tissue embedded in paraffin or collodion or to cryogenic freezing microtome sections. Cut into 10 ~ 5 microns thin slice, for optical microscope observation. With epoxy resin or methacrylic acid paraffin embedded tissue blocks of ultrathin sections were cut, the thickness in 20 ~ 50 nm, specifically for under electron microscope observed. General teaching such as root tip and stem sections known as paraffin sections.

cleaning method

clearance method: wash with water or alcohol to wash, and then use cotton or gauze to wipe clean (best with lens cleaning paper, fingers to avoid contact with the glass slide, in order to avoid the fingerprints, affect the next observed using)
