Benedict’s test is a chemical test that is used to test for the presence of reduced sugars within an analytical test. Thus, simple carbohydrates that contain an aldehyde or free ketone functional group are detected using this test. The test is basing itself upon Benedict’s Reagent (also called Benedict’s solution) which is a complex mix of sodium carbonate, sodium citrate, and the pentahydrate of copper(II) Sulfate.
An electron microscope is an instrument which produces an image of a sample by means of a beam of electrons. Optical microscopes use light to form an image, electron microscopes have greater resolution, and can be used to observe objects that are too small to be seen with an optical microscope. In a large variety … Read more
What is Baran Pipette Column? Principle of Baran Pipette Column Principles of adsorption chromatography are used in the Baran pipette column. In this technique, the separation of compounds is achieved through their differential interactions with two key phases: in the stationary phase and the mobile phase. The pasteur pipette is packed with a stationary phase, … Read more

What is an autoclave? An autoclave is a device which finds applications in numerous scientific and medical institutions. Its work principle lies in using the pressure of steam for the cleansing of equipment and materials. During the autoclaving process, the following kinds of germs are killed: bacteria, viruses, and spores. The basic idea of autoclave … Read more
What is gas chromatography? Gas chromatography (GC) is a sophisticated technique that separates, identifies, and quantifies chemical components in complex mixtures. It operates on the principle of distributing the components between a mobile phase and a stationary phase. In GC, the mobile phase is an inert gas like helium, and it acts as a carrier … Read more
What is Laboratory Incubator? An incubator serves as a temperature-controlled, insulated container that laboratories utilise for cultivating and maintaining various biological cultures. This essential piece of equipment creates optimal conditions necessary for growing microorganisms in artificial environments. Like most sophisticated lab instruments, it maintains precise control over environmental factors such as temp, moisture levels, and … Read more

What is Repeater Pipette? How Repeater Pipettes Work Repeater pipettes enable the precise and repetitive dispensing of liquid in equal volumes. They improve efficiency by eliminating the need for repeated aspiration. Here’s a breakdown of their operation: Mechanism of Action Parts of Repeater Pipettes Repeater pipettes are designed for precise and efficient liquid dispensing. They … Read more
What is mouth pipette? Principle of Mouth Pipette The working principle of mouth pipetting is based on the creation of a pressure differential, which allows for the movement of liquid into a pipette through suction. This method involves the use of a glass capillary tube, where one end is submerged in the liquid to be … Read more
