What is Electron Spin Resonance (ESR)? Working Principle of Electron Spin Resonance (ESR) How Does Electron Spin Resonance (ESR) Works? Instrumentation/Parts of Electron Spin Resonance (ESR) Component Function Klystrons Act as the radiation source; stabilized against temperature fluctuations; frequency controlled by voltage and an automatic circuit; power output around 300 milliwatts. Waveguide/Wavemeter Placed between oscillator … Read more

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

One of those methods you could find in biochemistry or biotech laboratories, particularly when someone has to separate a particular molecule from a complicated mixture, is affinity chromatography. Imagine attempting to locate a single buddy among throngs at a concert without a torch or means of communication. Working with proteins, enzymes, or antibodies in a … 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

What is Native Polyacrylamide Gel Electrophoresis? Principle of Native Polyacrylamide Gel Electrophoresis (PAGE) An analytical technique called SDS-PAGE (Polyacrylamide Gel Electrophoresis) separates protein mixture components according to size. The method is predicated on the idea that a charged molecule would migrate in an electric field toward an electrode of opposite sign. Since the mobility of … 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 McIntosh and Fildes’ Anaerobic Jar? Designed to provide an oxygen-free environment required for growing bacteria unable of surviving in the presence of oxygen, McIntosh and Fildes’ anaerobic jar is a specialist piece of laboratory equipment. Usually built from strong metal or glass, the jar has a firmly closing lid and has input and … Read more

The GasPak Anaerobic System is a laboratory method used to grow bacteria that thrive in oxygen-free environments, known as anaerobes. Using throwaway sachets filled with compounds like sodium borohydride and sodium bicarbonate helps to create an anaerobic (oxygen-free) environment more quickly. These molecules combine to generate hydrogen and carbon dioxide when water is introduced. The … Read more
