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

The technique of fluorescence spectrophotometry measures the intensity of light emitted by a substance after it has been excited by a certain wavelength of light. This method is employed to investigate the characteristics of molecules and detect the presence of specific chemicals in a sample. The origins of fluorescence spectrophotometry can be traced back to … Read more

Fluorescence spectroscopy is an analytical technique used to examine the characteristics and interactions of molecules. It is founded on the idea that when a molecule absorbs a photon of light and becomes excited, it emits light at a longer wavelength, a phenomenon known as fluorescence. This emitted light can be collected and studied in order … Read more

Samples are homogenised in rotor-stator homogenizers by mechanical tearing, shear fluid forces, and/or cavitation, with the rotor spinning rapidly inside a stationary outer sheath (stator) (the rapid forming and collapsing of bubbles). However, particularly tough tissue can be a challenge for rotor-stators when trying to homogenise cells or tissues. Although some high-throughput models and continuous … Read more

What Is a Bead Mill Homogenizer (Bead Homogenizer)? Bead mill homogenizers can lower the size of solid particles and disseminate them uniformly throughout a sample. The sample is broken up by aggressively and rapidly shaking a tube containing the beads and sample. As the beads hit with the sample (reducing particle size on a macro … Read more

What is a Beaker? A laboratory beaker is a cylindrical glass container with a flat bottom and a pouring spout, used to measure and mix liquids in scientific experiments. Beakers are an important piece of equipment in many scientific laboratories and play a crucial role in chemistry and other scientific fields. The history of the … Read more
