A hemocytometer is a laboratory counting chamber used for the manual counting of the cells in a suspension, and it is used in the biology, the clinical, and the hematology laboratories for the counting of the blood cells, the yeast cells, the sperm cells, and other cells. The hemocytometer consists of a thick glass slide with a counting chamber of a known depth, and a coverslip, and the counting chamber is divided into a grid of squares of the known dimensions, and the cell suspension is loaded into the chamber by the capillary action, and the cells in the grid squares are counted under a microscope, and the cell concentration is calculated from the count, the volume of the chamber, and the dilution factor; the hemocytometer provides a simple and economical method for the cell counting, and it is used for the counting of the red and the white blood cells, for the counting of the platelets, for the counting of the yeast and the bacteria, for the counting of the sperm, for the counting of the cells in the culture, and for many other applications, and it requires the proper preparation of the sample and the careful counting, and it may be used with the staining of the cells to improve the visibility; the hemocytometer is an essential instrument in the hematology and the biology laboratories, and it is available in various types, including the improved Neubauer chamber, which is the most common. Hemocytometers are used in the clinical laboratories for the blood cell counting, in the research laboratories for the cell counting, in the fertility clinics, in the breweries, and for many other applications. With their cell counting, hemocytometers are essential for the manual cell counting in the laboratory.

A double-sided vertical shaker is a laboratory instrument used to mix and agitate the samples in the tubes, the bottles, and the other containers, by a vertical reciprocating motion on two sides, and it is used in the biology, the chemistry, the clinical, and the environmental laboratories for the mixing of the samples, the extraction, the resuspension, and many other applications. The double-sided vertical shaker consists of a base with a motor and two vertical platforms or racks that hold the containers on both sides, and the platforms move up and down in a vertical reciprocating motion, agitating the contents of the containers; the vertical motion provides a vigorous mixing, and the double-sided design increases the capacity, allowing the shaking of many samples at the same time, and the shaker provides a variable speed, with features such as a timer and a digital display, and it is used for the mixing of the samples in the tubes, for the extraction of the analytes, for the resuspension of the pellets, for the mixing of the reagents, for the homogenization, and for many other applications; the double-sided vertical shaker is available in various sizes, with the different holders for the containers, and it is compact and sturdy, and it is an essential instrument for the mixing in the laboratory. Double-sided vertical shakers are used in the clinical laboratories for the mixing of the blood samples, in the chemistry laboratories for the extraction, in the environmental laboratories, in the food industry, and for many other applications. With their vigorous mixing, double-sided vertical shakers are essential for the sample mixing in the laboratory.
