McIntosh and Fildes’s anaerobic jar is a tool utilized in microbiology laboratories, to generate anaerobic circumstances (anaerobiosis) to cultivate obligate anaerobes, such as Clostridium spp. Anaerobiosis derived from McIntosh and Fildes anaerobic jar is among the most effective and most frequently employed methods for anaerobiosis however it requires expensive special equipment and a vacuum pump. … Read more
GasPak anaerobic system is utilized to create an oxygen-free atmosphere to encourage the growth of microorganisms that live in anaerobic environments. In the present, it is the most frequently utilized method for anaerobiosis. It is easy to do and works well for laboratories with a smaller amount of samples. Components of GasPak Anaerobic System Principle … Read more
What is BOD Incubator? BOD incubator Definition The BOD (Biological Oxygen Demand) Incubator is a specialized laboratory instrument designed to provide a controlled temperature environment, typically around 20 degrees centigrade, for microbial and biochemical studies, particularly for assessing the oxygen demand of microorganisms in water samples. BOD incubator Principle Components of BOD Incubator The BOD … Read more
What is Oil Immersion? What is Microscopic Resolution? Microscopic Resolution Definition The microscopic resolution also is known as resolving power. Resolution is defined as the ability of a lens to separate or distinguish between small objects that are close together or the ability to distinguish two adjacent points as distinct and separate. Equation of Microscopic … Read more
Differential centrifugation (also called the differential velocity method) is a common process in the fields of biochemistry and cell biology it is utilized to differentiate organelles and other subcellular particles by their sedimentation rates. Although it is commonly used in biochemical analysis it is a general method that is useful for the crude elimination of … Read more
Autoclaving is one method that uses steam to sterilize. Autoclave bags are utilized for sterilization at high temperatures to keep low-temperature plastics in the autoclave bags from sticking against the side of the sterilizer or obstructing the plumbing for the sterilizer’s vent. Autoclaves function by using a combination of pressure, steam, and time. They work … Read more
Density Gradient Centrifugation Density gradient centrifugation refers to an approach to separation between molecules, where the separation is determined by the density of the molecules when they travel through a gradient under the force of centrifugal. Principle of Density gradient centrifugation Density gradient centrifugation relies on the premise that molecules settle under the force of … Read more
What is Laminar flow hood/cabinet? Definition of Laminar flow Laminar flow refers to the smooth, uninterrupted flow of fluid, such as air or liquid, in parallel layers without any significant mixing or turbulence. Principle of Laminar flow hood The working principle of a laminar flow hood is based on creating a controlled airflow within the … Read more
What is transmission electron microscope? Parts of A Transmission Electron Microscope 1. Electron Gun Types of Electron Gun Used in Transmission Electron Microscope There are several types of electron guns that are used in transmission electron microscopes (TEMs), including: Overall, the type of electron gun used in a TEM depends on the specific requirements and … Read more
A scanning electron microscope (SEM) is a type of electron microscope that generates images by scanning the surface of a specimen with a concentrated beam of electrons. Electrons interact with atoms in the sample, generating signals that carry information about the sample’s surface topography and composition. The electron beam is scanned in a raster scan … Read more
