A microscope slide (top) and a cover slip (bottom) A microscope slide is a thin flat piece of glass, typically 75 by 26 mm (3 by 1 inches) and about 1 mm thick, used to hold objects for examination under a microscope. Typically the object is mounted (secured) on the slide, and then both are inserted together in the microscope for viewing. This ...
A SAP's ability to absorb water depends on the ionic concentration of the aqueous solution. In deionized and distilled water, a SAP may absorb 300 times its weight [ 4 ] (from 30 to 60 times its own volume) and can become up to 99.9% liquid, and when put into a 0.9% saline solution the absorbency drops to approximately 50 times its weight.
Mostly air under the cover slip – too little water was used or the cover slip was improperly dropped onto specimen. Adding a drop of water to the slide at the very edge of the cover slip will result in water being taken in under the cover glass via capillary action. If numerous air spaces are still evident, it is best to start over.
The counting chamber should be filled by capillary action after the chamber lid (special cover-slip with certified thickness and flatness) has been put in place. This avoids the risk that the cells could sediment/stick to the glass or some volume to evaporate before the cover-slip is placed on top and resulting in an overestimation of the cell ...
Some microscopes make use of oil-immersion objectives or water-immersion objectives for greater resolution at high magnification. These are used with index-matching material such as immersion oil or water and a matched cover slip between the objective lens and the sample. The refractive index of the index-matching material is higher than air ...
Spotted cat breeds are both rare and beautiful. They are popular with owners but can be expensive to purchase as there are not that many breeders. Some are entirely domestic but others are hybrid ...

In the 21st century, most folks have either delivered something as a job or have had something delivered to them. In most cases, probably both. So it stands to reason that at some point, you are ...
