Nylander’s test is a qualitative test that is used for detecting reducing sugars. It is the process where the reducing sugar is heated with an alkaline solution containing bismuth salt, and the reaction is controlled by the components present in the reagent. The reagent is made of bismuth nitrate or bismuth subnitrate, potassium sodium tartrate, … Read more
The Picric Acid Test is used to detect the presence of reducing sugars in a solution. It is a general chemical test and it is based on the reduction of picric acid under alkaline condition. Picric acid is a yellow crystalline compound (2,4,6-trinitrophenol) and it is converted into picramic acid when it reacts with a … Read more
Gradient PCR is referred to as a PCR optimization method where a range of annealing temperatures is tested at the same time in a single run. It is done in a thermal cycler that contain a gradient block, and this block is made in such way that one side hold lower temperature while the opposite … Read more
What is Bright Field Microscope? Bright field microscope is an optical microscope that produce a dark image of the specimen against a bright background, and it is the most common compound light microscope used in biological laboratories. It is the system where the specimen is illuminated from below by a uniform beam of light, and … Read more
What is Ocular Micrometer? The ocular micrometer, which many student’s usually call as the eyepiece micrometer, is basically a small circular glass disk that stay fitted inside the microscope eyepiece, and it carry a tiny ruled scale engraved on it. In general terms, this scale look like a simple series of line’s, but it is … Read more
What is Toolmakers Microscope? The Toolmaker’s Microscope is referred to as a compact Precision optical device that is utilized for measurement rather than ordinary viewing, and it projects a magnified shadow-image of a component’s contour in to an eyepiece or screen. It is considered to be contactless equipment, which is necessary for measuring very thin … Read more
The Atomic Absorption Spectrophotometer (AAS) is referred to as an analytical instrument that measures the absorption of specific Light wavelength’s by free atom’s, which is required for determining metal concentration in a sample. It is considered a method where atoms in the Ground State absorbs radiation, leading to characteristic signals that are recorded by the … Read more
What is Color Spectrophotometer? A color spectrophotometer is referred to as an optical instrument that is utilized for measuring the intensity of light at various wavelength’s, which gives a look into how a sample’s surface reflect or absorb color’s in a quite systematic way. It is considered a device that records the reflectance spectrum, which … Read more
What are Microscopes? A microscope can define as an optical or electronic Instrument that is used for observing objects’ that are too small for the naked eye, and it gives a look into structures in biology/physics etc. In general terms, the device is characterized by lenses, illumination sources, and also by Magnification system’s that allow … Read more
A centrifuge can define as a laboratory device that use rapid rotational Force to separate component’s of a mixture based on their Density difference’s, and it is considered a key Instrumentation in many biological / chemical workflows. What is Relative Centrifugal Force (RCF)? Relative Centrifugal Force (RCF) is the effective acceleration a particle experiences in … Read more
