A scanning electron microscope (SEM) produces high-resolution images from an electron beam that scans a focused beam over the surface of a specimen. The benefit of using electrons as opposed to an optical light microscope is that, due to electronegativity, the resultant interactions with the orbitals surrounding the atom create signals that indicate surface morphology … Read more
What is phase contrast microscopy? Okay, so picture this: back in the 1930s, scientists were struggling to study things like living cells or bacteria under a microscope. Why? Because those tiny critters are practically see-through! You couldn’t get a clear look without dunking them in harsh dyes—which, you know, kinda killed them. Not exactly helpful if you … Read more
Confocal microscopy offers some pretty cool perks compared to regular optical microscopes. For starters, it gives you a razor-thin focus depth, cuts out that annoying blurry background glow, and lets you snap crisp, detailed “slices” of thick samples—one after another. This makes it a go-to tool in biomedicine, especially for studying cells and tissues, whether … Read more
What is a Dissecting microscope or a Stereo microscope? A dissecting microscope—also known as a stereo microscope—is an optical microscope study apparatus that enables the observation of an object at low to moderate magnification (typically 5x to 250x) through reflective light versus transmitted light. Thus, it’s a microscope made for viewing little details that could … Read more
Designed to enlarge things too tiny for the human eye to see, a microscope is a tool. It provides a portal to the hidden world of minute structures, allowing medical practitioners, teachers, and researchers to examine materials, cells, and creatures in until unheard-of clarity. Microscopes range significantly in kind, from simple to very sophisticated models. … Read more
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
