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. Gas supply availability is another drawback to this technique. It is currently being replaced with an easier GasPak system.
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.
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
Incubator definition An incubator is an insulated and enclosed device used in biological laboratories. It creates an optimum environment which is required for the growth of microorganisms by providing optimum temperature, humidity, and other environmental conditions such as the CO2 and oxygen content inside’s atmosphere. In laboratories, it is used to grow and maintain microbiological … Read more
What is Oil Immersion? Oil immersion is a technique, used to increase the resolving power or microscopic resolution of a light microscope. This is done by immersing the objective lens and specimen into a transparent oil containing a high refractive index, as a result, it increases the numerical aperture of the objective lens. The immersion … Read more
Stereo microscopes, in contrast to compound light microscopes, often employ reflected illumination, or light reflected off an object’s surface, rather than transmitted (diascopic) illumination. When a specimen is too thick or opaque for compound microscopy, reflected light from the object enables for investigation. Unlike a compound microscope, transmitted illumination in most stereo microscopes is not … Read more
Confocal microscopy has various advantages over conventional optical microscopy, including a short depth of field, the elimination of out-of-focus glare, and the ability to collect optical slices serially from thick specimens. A prominent use of confocal microscopy in the biomedical sciences is the imaging of either fixed or live cells and tissues that have typically … Read more
What is phase contrast microscopy? A phase contrast microscopy converts slight differences in refractive index and cell density into easily detected variation in light intensity to observe living cells. This microscope is used for visualization of cell culture and live cells. Living cells can be observed without any staining. Unstained specimens have absorbed no light, … 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
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
An electron microscope is a type of microscope that uses a beam of electrons to create an image of a sample. Electron microscopes have a higher resolution than optical microscopes, which use light to form an image, and can be used to observe objects that are too small to be seen with an optical microscope. … Read more
A microscope is a scientific instrument that is used to magnify the image of an object or sample in order to study its structure or features in detail. Microscopes are commonly used in scientific and medical research, as well as in education and other applications, to study small structures and organisms that are not visible … Read more
The history of the simple microscope can be traced back to the 17th century, when it was first developed by Dutch mathematician and astronomer, Christiaan Huygens. Huygens designed a simple microscope that used a single converging lens to magnify the image of an object, similar to the design of a modern refracting simple microscope. The … Read more
