What is ultracentrifuge?

Ultracentrifuge is a tool designed to rotate the object around a fixed axis using perpendicular force. Ultracentrifugation is performed at a speed of faster than 20,000 rpm and is used to separate small particles apart to determine their size and molecular weight. It is also used to study high polymers, especially proteins, nucleic acids, viruses and other biological macromolecules. There are preparative and analytical ultracentrifuges and both are used in polymer science, biochemistry and molecular biology.

Preparatory ultracentrifuge is used to insulate specific particles for reuse. It is considered a high -performance tool that is reliable and efficient and works quickly and quietly. It is equipped with a number of rotors that are suitable for a number of separation tasks used in cellular biology, biochemistry and molecular biology. The sample can be shaken at high speed until its components are separated. Most preparatory ultracentrifugation units include a carRotor management, color LCD screen and positive feedback.

Analytical centrifugation is a widely used biomolecular research technique that measures the physical properties of sedimentant particles and the way they behave in a state of solutions. Theodor Sedberg invented the analytical ultracentrifuge and won the Nobel Prize in Chemistry for the research he did with him. In this type of ultracentrifuge, the sample is spinned in the cell and the optical system projects a cell image on a computer or film in real time. The most common types of analytical ultracentrifugation experiments are experiments in sedimentation speed and balance that offer information about shapes, sizes and conformation changes of macromolecules.

Using Ultracentrifug, there are dangerous hazards because it works at very high speeds and often uses solutions that include hard chemicals. Both of these factors to createThey tend to mechanical tension that can cause rotor wear. In addition, the rotors must be properly loaded and exported, or may be released, causing considerable damage, injury and even explosion. Each tool should receive regular maintenance and users should be properly trained to record it properly and balance and clean rotors.
