Multi-Mode Microplate Reader LMMR-A10

Our Multi-mode reader is beneficial for labs conducting a wide range of scientific experiments starting from Immunosorbent assays and cell imaging to protein and nucleic acid quantification. Combining multiple microplate technologies and detection modes into a single, more versatile unit is an ideal choice when space is a limitation factor.

Colorimetric assays, bacterial growth assays, ELISA, nucleic acid and protein identification as well as quantification can be performed in the Absorbance mode, DNA quantification, RNA quantification, enzyme kinetics, cell quantification, fluorescence-based immunosorbent assays can be performed in Fluorescence mode and reporter gene assays, ATP quantification, kinase assays, cytotoxicity, cell viability assays can be implemented using the Luminescence mode, along with many other applications.

A Microplate Reader, commonly called as plate reader or plate spectrophotometer, is an analytical instrument that reads or detects the physical, chemical, and biological events of the analyte, within the wells of the plate. It has numerous tiny wells where the sample analyte is introduced for analysis.

A standard spectrophotometer measures the absorbance of one sample at a time. The sample is typically placed in a cuvette through which light is sent horizontally. An absorbance plate reader offers higher throughput and can measure the absorbance of samples in microplates (typically 96-well or even 384-well) by sending light through each well vertically.

Microplate-based measurements detect light signals produced by a sample, converted by a sample, or transmitted through a sample. In the plate reader, the signal is measured by a detector, usually a photomultiplier tube (PMT). PMTs convert photons into electricity that is then quantified by the microplate reader. The output of this process is numbers by which a sample is quantified.

Tungsten-halogen or xenon flash lamps are generally used. LEDs have also come into the picture in some modern readers.

The detection technology can be of 3 types- Monochromator based detection which provides flexibility, convenience, and spectral scanning; Filter based detection which enables rapid switch between different wavelengths; Hybrid detection which has dual technological advantage of both flexibility and sensitivity.
