Flow meters are instruments used to measure the flow of liquids or gas. These fluids may be linear, nonlinear, mass, or volume. Flow meters are also referred to as flow sensors depending on a particular industry. There are many flow meters to choose from.
The Internet has become the most efficient source of info. For all kinds of data, you rest assured to get something that adds value or suits your needs. Bloggers are full of valuable data that satisfies all your queries. Even when seeking to know or buy a flow switch, they…
Are you looking for the liquid Flowmeter guide? In this article, you will learn more about the rate of flow of water. This tool is used to measure the volume and quantity of the liquid flowing in a pipe. Each flow meter has an advantage for the user. Many pipes…
In any mechanical industry, gauging devices are very vital. These devices are used to check the flow measurement as well as the energy value in the industry. There are many water flow measurement devices available in the market. But, picking the right tool is never a walk in the park.…
Laboratory ovens are standard equipment found in most research, clinical and forensic laboratories. Ovens are available in gravity (natural), mechanical (forced) convection, and vacuum pump for routine heating and drying applications. For labs with temperature uniformity, stability and accuracy requirements, advanced protocol ovens are available to meet demanding requirements. Convection…
Fume hoods are devices that are commonly used in laboratories and research facilities that deal with toxic substances. Their main purpose is to properly ventilate the hazardous vapors and toxic fumes which are produced by certain materials. When working with such dangerous materials, the toxic gases that are emitted can…
Necessity is the mother of invention, rightly said, from the invention of sundials to the latest stopwatch, technology has evolved slowly but surely and great things have come into being. Scientists, tech companies and laboratory equipment suppliers all are the part of this evolution and hence, need to be updated.
Because diagnoses and treatment plans are made based on laboratory findings, it is imperative that the equipment utilized in the lab be in excellent working order, serviced at regular intervals, calibrated and cleaned as recommended by the manufacturer, and used properly. In addition to properly functioning equipment, there are things…
Automated hematology analyzers work on different principles: Electrical impedance Light scatter Fluorescence Light absorption Electrical conductivity. Most analyzers are based on a combination of different principles. (1) Electrical impedance: This is the classic and timetested technology for counting cellular elements of blood. As this method of cell…
FLOW CYTOMETRY Flow cytometry is a procedure used for measuring multiple cellular and fluorescent properties of cells when they flow as a single cell suspension through a laser beam by a specialized instrument called as a flow cytometer. Flow cytometry can analyze numerous cells in a short time and…
Fluorescence A fluorochrome absorbs light energy and emits excess energy in the form of photon light (fluorescence). Fluorescence is the property of molecules to absorb light at one wavelength and emit light at a longer wavelength. The fluorescent dyes commonly used in flow cytometry are fluorescein isothiocyanate (FITC) and…
Leukemias and lympomas: Immunophenotyping (evaluation of cell surface markers), diagnosis, detection of minimal residual disease, and to identify prognostically important subgroups. Paroxysmal nocturnal hemoglobinuria: Deficiency of CD 55 and CD 59. Hematopoietic stem cell transplantation: Enumeration of CD34+ stem cells. Feto-maternal hemorrhage: Detection and quantitation of foetal hemoglobin in maternal…
The first fluorescence-based flow cytometry device (ICP 11) was developed in 1968 by Wolfgang Göhde from the University of Münster, Germany and first commercialized in 1968/69 by German developer and manufacturer Partec through Phywe AG in Göttingen. At that time, absorption methods were still widely favored by other scientists over…
Use the Reference manual for in-depth information on the principles of flow cytometry, information about what your instrument does, the methods it uses, its specifications, and information on installation, safety, and system options.Use the Getting Started manual to become familiar with the controls and indicators for your system and to…
