A spectrophotometer cuvette is a small optical cell that is used to hold the liquid sample during absorbance or transmittance measurement. It is usually made in a rectangular shape and two opposite sides are kept clear and highly polished so that the light beam can pass through the solution without scattering. It is the process … Read more
A pH meter is an instrument that is used to measure the pH of a solution, and it is the value that shows how acidic or alkaline the solution is. It is the process where a glass electrode and a reference electrode are placed in the sample, and the potential difference formed between them is … 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 is a Bioreactor? A bioreactor can define as a controlled Vessel where biological’ process are carried out for growing cells, microorganism’s, or enzymes, and It is considered an essential component of many Industrial Biotechnology fields . Definition of Bioreactor A bioreactor is a device or system used to cultivate and grow biological cells, tissues, … 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
