A BOD incubator is a laboratory instrument that is used for maintaining a controlled temperature environment required for the estimation of Biochemical Oxygen Demand of water samples. It is designed to operate both at heating and cooling conditions which is different from ordinary incubators. It is mainly adjusted at a fixed temperature of 20°C which … Read more
A lipase test is a laboratory diagnostic test which is done to measure the level of lipase enzyme in the blood. Lipase is a digestive enzyme which is mainly produced by pancreas and it helps in digestion of fats. It is the process in which dietary triglycerides are broken down into fatty acids and glycerol … Read more
The purpose of the malonate test is to see if the organism can get all of its energy from malonate.
The oxidase enzyme is a key factor in distinguishing Staphylococcus from Micrococcus, and the Microdase Disk is a reagent-impregnated disc recommended for use in qualitative procedures.
What is API (Analytical Profile Index) 20E Test? The API (Analytical Profile Index) 20E test is a standardized biochemical identification system used for the identification of Enterobacteriaceae and other non-fastidious Gram-negative rods. It is developed as a miniaturized system where a number of biochemical reactions are carried out simultaneously in a single plastic strip. It … Read more
Affinity chromatography is a type of liquid chromatography technique which is used for separation and purification of biomolecules based on a highly specific and reversible interaction between the target molecule and a specific ligand. It is the process where the target molecule selectively binds with a ligand that is immobilized on a solid matrix. This … Read more
A bench top centrifuge is a laboratory instrument which is used for separation of components present in a liquid sample based on their density. It is a compact device that is designed to be placed on laboratory bench and is commonly used in routine laboratory work. It is the process in which centrifugal force is … Read more
A hematocrit centrifuge is a laboratory instrument which is used to determine the hematocrit value of blood. It is the percentage volume of red blood cells present in the total volume of whole blood and this value is also referred to as packed cell volume (PCV). It is commonly used in hematology laboratories for routine … Read more
In negative staining method, an acidic dye is used known as India Ink or Nigrosin. When the bacterial cells are exposed to this stain, due to the presence of acidic nature it readily gives up a hydrogen ion (proton) and the chromophore. As a result, the dye becomes negatively charged, now the bacterial cell surface deflects the stain.
The main purpose of simple staining is to determine the cell shape, size, and arrangement of bacterial cells.
