Autoclave Bag – Application, Types, Applications, Advantages

Autoclave Bag - Application, Types, Applications, Advantages

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 – Principle, Protocol, Uses

Density Gradient Centrifugation Principle, Protocol, Uses

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

Scanning Electron Microscope: Definition, Parts, Application, Principle, Advantages

Scanning Electron Microscope

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

Phase Contrast Microscopy: definition, parts, uses, working principle.

Phase Contrast Microscopy

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

Confocal Microscope Principle, Uses, Parts, Advantages, and Disadvantages.

Confocal Microscope Principle, Uses, Parts, Advantages, and Disadvantages.

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
