What is Pulsed-field Gel Electrophoresis (PFGE)? Principle of Pulsed Field Gel Electrophoresis (PFGE) The principle of pulsed-field gel electrophoresis (PFGE) revolves around the separation of DNA fragments based on their size using an electric field. In conventional gel electrophoresis, small DNA fragments migrate more easily through the gel matrix than large fragments. However, when dealing … Read more

What is PCR Machine? Principle of PCR The polymerase chain reaction (PCR) is based on a set of principles that enable the amplification of specific DNA sequences. The key components involved in PCR are the template DNA, DNA primers, DNA polymerase enzyme, and deoxynucleotide substrates. The principle of PCR begins with the selection of a … Read more

What is a Spectrophotometer? Definition of Spectrophotometer A spectrophotometer is a laboratory instrument that measures the amount of light absorbed by a sample and is used to determine properties such as concentration or absorption patterns of substances. Principle of Spectrophotometer Spectrophotometry is a scientific technique that quantifies the intensity of light as a function of … Read more

A Single-Use Bioreactor (SUB) is a type of bioreactor that is used for a single batch of culture and then disposed of, as opposed to being cleaned and reused. The bioreactor is made of plastic or other disposable materials, such as polymeric bags or containers. These materials are used for the cultivation of cells, microorganisms, … Read more

A tissue homogenizer is a laboratory tool used to disrupt cells and tissues by mechanical means, such as grinding, blending, or shaking. It is commonly used in biology and biochemistry research to extract cellular components, such as proteins and nucleic acids, for further analysis. Homogenizers come in different types, including manual and mechanical versions, and … Read more

What is Ultrasonic Homogenizers? Principle of Ultrasonic Homogenizers The ultrasonic power supply converts line voltage to 20 kHz electrical energy at high frequency. This electrical energy is sent to the probe, which converts it into mechanical energy. The probe’s vibrations are connected to and amplified by the titanium tip. This longitudinal vibration is transmitted to … Read more

What is Homogenizer? What is High Pressure Homogenizer? Working principle of high pressure homogenizer High-pressure homogenization involves the use of high-pressure, compressed liquid material that flows through the gap at high speeds and is subjected to intense shear stresses. The collision of the liquid material on the metal ring generates a powerful impact force and … Read more
