Guide and selection support
Plate readers are used for the analysis of samples in microtiter plates, for example in ELISA, protein quantification, or cell culture assays. These instruments support various detection methods such as absorbance or fluorescence measurements.
Key factors when selecting a plate reader include the available detection modes, measurement accuracy, throughput capacity, and compatibility with different plate types. Features like multimode capability can offer additional flexibility.
LabFinder provides a structured overview of plate readers, helping users find devices based on application and technical characteristics. This facilitates procurement decisions and makes it easier to compare different models.
Applications and Benefits
Plate readers are used to measure and evaluate biological, chemical, and physical reactions in microtiter plates. They allow analysis of assays such as ELISAs, protein and cell growth tests, nucleic acid quantification, immunoassays, and high-throughput screenings. In doing so, optical signals are detected, which provide information about sample properties and are used in research, diagnostics, or quality control.
Selection Criteria
Key selection criteria include the detection principle offered (e.g. absorbance, fluorescence, luminescence, fluorescence polarization), the number of samples that can be measured simultaneously, and compatibility with various plate types and formats. Other considerations are ease of use, software functions for data analysis, and possible multimode capabilities that combine multiple detection modes in one instrument.
Variants and Detection Principles
The main variants of plate readers differ according to their detection principle. Absorbance readers are commonly used for color intensity measurement, fluorescence readers allow sensitive detection of specific markers, while luminescence readers are optimized for detecting very low signal levels. Multimode readers integrate several of these principles for versatile applications.
Calibration and Maintenance
Regular calibration, maintenance, and cleaning are essential for reliable measurement results. Calibration is often performed using defined standards or control samples. Manufacturer guidelines for maintenance help ensure optimal functionality and extend the instrument’s service life.
Limitations of Use
Plate readers are limited to microtiter plates as sample vessels and can be influenced by interfering factors such as sample matrix or light scattering depending on the detection principle. Not all signal types are suitable for every type of plate reader, which should be considered when selecting an instrument. Additionally, they are designed for raw data measurement and usually require additional software for complex data analysis.
