hemacytometer

 [he″mah-si-tom´ĕ-ter]
a device used for manual blood counts, consisting of a counting chamber of uniform depth that is covered by a ruled cover glass so that the region under each ruled square contains a known volume of the diluted specimen. Called also hemocytometer.

he·mo·cy·tom·e·ter

(hē'mō-sī-tom'ĕ-tĕr),
An apparatus for estimating the number of blood cells in a quantitatively measured volume of blood; it consists of a glass pipette with an ampulla for collecting and diluting the blood, and a counting chamber marked in squares.

Size and morphology analysis was performed on reconstituted MAA using an optical microscope (Micromaster, Fisher-Sci, USA) and a hemacytometer (Reichert, USA) before and after relyophilization.
After all of the worms had died (longevity studies) or after 10 days of culture, the number of eggs deposited in culture was counted on a hemacytometer.
Subsequently, the appropriate volume was transferred to a hemacytometer and WBCs counted under a microscope.
Then, 20-[micro]L aliquot was removed and placed on a Neubauer hemacytometer. Finally, the number of viable cells was counted under light microscopy.
Suspensions of 105 conidia/mL (as measured with a hemacytometer) were prepared with sterile distilled water and used in all inoculation procedures.
The cell concentrations of the diatom species were counted by direct counts using a hemacytometer and a compound microscope.
Afterward, cultured cells were extensively washed with PBS (PAA, H15-002) and both cell viability and concentration were calculated by trypan blue exclusion assay followed by examination with a hemacytometer under an optical microscope.
Conidial suspension of the isolate was prepared from fungi which growed for 10 days on PDA cultures, and the conidial concentration was adjusted to 2 x 105/ml using hemacytometer. The gerbera plants were cultivated at regular intervals in pots with sterile soil mixture and they were spray-inoculated with 100 ml of the spore suspension per pot.
