What is Chromatography? Definition of Chromatography Chromatography is a laboratory technique for the separation of a mixture by passing it in a solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates. How does Chromatography work? Applications Of Chromatography Because chromatography can separate, … Read more
What is spectroscopy? Types of Spectroscopy Spectroscopy encompasses a broad range of techniques based on the interaction between light and matter, each with its own unique applications and principles. Here’s an overview of some key types: Each spectroscopic method brings unique insights into the physical, chemical, and structural properties of materials, finding applications across science, … Read more
An ultracentrifuge is one of those lab tools that might not grab headlines, but behind the scenes, it’s a game-changer for scientists. Picture a high-tech spin machine—way more intense than your average centrifuge. It whirs at mind-blowing speeds, sometimes hitting hundreds of thousands of rotations per minute. The force it creates? Imagine gravity cranked up … Read more
One of those methods you’ve most likely heard of in passing, particularly if you have ever dipped a toe into chemistry or seen a crime thriller where they examine unidentified drugs, is chromatography. Fundamentally, it’s a means of separating difficult combinations into their component elements. Imagine you want to know what’s really in there and … Read more
Microbiology laboratories require well-built rooms that are equipped with tools, glassware and equipment. Test tubes, culture tubes, Petri dishes and Erlenmeyer flasks are the most important types of glassware in a microbiological lab. 1. Test tube Usually composed of glass or transparent plastic, a test tube is a standard piece of laboratory equipment distinguished by … Read more
What is an Inverted Microscope? An inverted microscope is literally an inverted microscope. The lights and lenses are positioned above the specimen stage and the objective lenses are below. This allows the user to critically observe the samples from below; this is important because many living specimens and cells to be observed are in petri … Read more
What is Dark Field Microscopy? Darkfield microscopy is a form of light microscopy that facilitates detection by contrast. For example, brightfield microscopy uses a light source that shines light directly through the sample in order to illuminate the sample from below; darkfield microscopy uses a condenser that shines light at an oblique angle so that … Read more
What is Semiconductor Sequencing? Semiconductor sequencing is the integration of microchip technology with DNA sequencing where electrical signals replace the detection of light. This sequencing method is unique because it uses complementary metal-oxide semiconductor chips associated with sequencing by synthesis chemistry; so, in this respect, it opens up opportunities to make DNA analysis quicker and … Read more
What is Thyroid Gland? Definition of Thyroid Gland The thyroid gland is a butterfly-shaped endocrine organ located in the anterior neck that produces hormones such as thyroxine (T4), triiodothyronine (T3), and calcitonin, which regulate metabolism, growth, and calcium homeostasis. It plays a crucial role in maintaining the body’s metabolic rate and overall hormonal balance. Anatomical … Read more
Rickettsia is a small, Gram-negative, obligately intracellular bacterium. It is the organism which can grow and multiply only inside the living host cell. It is highly specialized bacteria showing extreme genomic reduction. Due to this, many metabolic pathways are absent and the bacteria is unable to synthesize its own energy. It depends on the host … Read more
