What is the meaning of microplate reader?
A microplate reader is a laboratory instrument that is used to measure chemical, biological or physical reactions, properties and analytes within the well of a microplate. A microplate reader can handle up to 3456 samples in minutes or even seconds.
What is a microplate absorbance reader?
The iMark™ Microplate Absorbance Reader, with a wavelength range of 400–750 nm, is an economical, high-performance solution for a wide range of applications, including immunoassays with colorimetric substrates, such as ELISA, and protein assays such as Bradford and Lowry.
What is an absorbance reader?
An absorbance microplate reader, (longform: absorbance microplate reader; shortform: absorbance reader), is a piece of equipment capable of detecting and quantifying the light photons absorbed/transmitted by a liquid sample present in a microplate, when exposed to light at a specific wavelength.
What is ELISA microplate reader?
An ELISA reader measures and quantitates the color differences in the 12 wells of the plate. ELISA readers or micro plate readers do spectrophotometry; they emit light at one wave length, and measure the amount of light absorbed and reflected by an object such as a protein.
Is a microplate reader a spectrophotometer?
Microplate Readers, or Plate Readers, are a type of spectrophotometer. Both use either a monochromator system or filter-based optics and these lab instruments both collect useful measurements across a variety of methods.
How does a fluorescent plate reader work?
The emission system of the plate reader uses polarizing filters to analyze the polarity of the emitted light. A low level of polarization indicates that small fluorescent molecules move freely in the sample. A high level of polarization indicates that fluorescent is attached to a larger molecular complex.
How much is a microplate reader?
BioTek’s simplest ELISA reader, for instance, costs about $5,000, says Xavier Amouretti, product marketing manager at BioTek Instruments, a company that sells a range of microplate reader systems; the company’s least-expensive multimode reader, the Synergy™ HT, costs about $20,000.
What is the difference between microplate reader and spectrophotometer?
The biggest difference between a microplate reader and a spectrophotometer is sample size. A typical spectrophotometer like the Thermo Nanodrop works with samples held in a cuvette, measuring just 1-2 uL at a time. A plate reader on the other hand works with multiwell plates to cover more ground in less time.
What is ELISA microplate reader used for?
Microplate readers detect and process biological and chemical data using absorbance (ELISAs, enzyme activity, and nucleic acid and protein quantification), luminescence, and fluorescence detection modes, including intensity, TRF, and polarization.

What is a fluorescence microplate reader?
A fluorescence plate reader, (longform: fluorescence microplate reader; shortform: fluorescence reader) also called spectrofluorometer or fluorometer, is a piece of equipment capable of detecting and quantifying the light photons emitted by a fluorescent sample present in a microplate upon excitation with light at a …
What is the purpose of a microplate reader?
What is a Microplate Reader? A microplate reader is a laboratory instrument that is used to measure chemical, biological or physical reactions, properties and analytes within the well of a microplate. A microplate consists of small wells in which separated reactions take place.
Which is the correct name for a micro plate?
A microplate or microtiter plate (spelled Microtiter is a registered trade name in the United States), microwell plate, multiwell, is a flat plate with multiple “wells” used as small test tubes. The microplate has become a standard tool in analytical research and clinical diagnostic testing laboratories.
How is a plate reader used in a well?
The plate reader software has a graphical user interface of the plate that allows you to select which wells are loaded with samples. Multichannel pipettes are often used to load multi-well plates.
What can be used as a microplate material?
Glass is also a common material, and vacuum forming can be used with many other plastics such as polycarbonate. Composite microplates, filter bottom plates, solid phase extraction (SPE) plates, and even some advanced PCR plate designs use multiple components which are moulded separately and later assembled into a finished product.
