What is a license plate reader: Definition
A plate reader is a measuring device used to analyze the contents of a microplate by quantifying optical signals such as absorbance, fluorescence, or luminescence. Each well of the plate, which can contain different samples, is read quickly and automatically. This data provides accurate results for:
- Enzymatic dosage (e.g. ELISA).
- Quantification of nucleic acids (DNA, RNA).
- Measurement of fluorescence intensity in labeled cells.
- Monitoring cell growth by absorbance.
- Molecular binding studies by luminescence.
The plate reader thus facilitates serial analyses while increasing the reliability and speed of results.
96-well plate reader: the standard configuration for laboratories
The 96-well plate reader is one of the most widely used formats in laboratories today. Why? Because it offers an excellent compromise between sample capacity and ease of analysis.
Advantages of a 96-well plate reader
- Simultaneous analysis of 96 samples with high precision.
- Compatibility with most ELISA kits, enzymatic assays and cytotoxicity tests.
- Easy standardization of laboratory protocols.
- Significant time savings for high-throughput screening.
For more specific needs, some readers also offer 384-well formats for mass screening, or 48-well formats for applications requiring more volume per sample.
Microplate reader: which types of detection should you choose?
The microplate reader can integrate different types of detection, depending on the nature of the experiments:
Absorbance detection
Allows you to measure the optical density of a sample based on the amount of light absorbed. Ideal for colorimetric assays such as standard ELISAs.
Fluorescence detection
Used to detect light emitted by fluorophores, it is crucial for cell labeling, protein quantification and quantitative PCR (qPCR).
Luminescence detection
Useful for ultra-sensitive tests, such as enzyme activity, reporter-gene (luciferase) tests or detection of low amounts of DNA/RNA.
Multi-mode detection
Some devices combine multiple detection types in a single instrument, providing maximum flexibility for multi-purpose laboratories.
If your protocols require multiple analysis methods, investing in a multi-mode plate reader may be worthwhile.
Selection criteria for your license plate reader
Before investing, it is important to evaluate the following criteria:
- Required detection mode : absorbance, fluorescence, luminescence or multimode.
- Optical resolution : quality and sensitivity of reading (expressed in nm).
- Analysis software : intuitive, compatible with your protocols.
- Kinetic reading capability to track the evolution of a reaction over time.
- Dimensions and type of compatible plates .
- Ease of maintenance and availability of spare parts.

ELISA plate reader price: what to expect?
The ELISA plate reader price depends on several factors: the integrated technology (single absorbance or multimode), the brand (BioTek, Thermo Fisher, Tecan...), and the condition (new or refurbished).
On average:
- An entry-level ELISA reader costs between €3,000 and €7,000 new.
- A multi-mode ELISA reader can cost €15,000 or more.
- By reconditioning at Rewake, you can get a high-performance model for between €1,500 and €5,000, a saving of 40 to 60%.
Our selection provides rigorously tested devices, backed by a warranty and technical support, so you can work with confidence.
Buying a digital license plate reader: how to make the right choice?
When considering a digital license plate reader purchase , there are several factors that should guide your decision:
- Type of detection required: absorbance only, or multimode?
- Integrated software : ability to create custom protocols, data export.
- Scalability : ability to add additional modules (e.g., stirring, temperature control).
-
Compatibility with other equipment such as a laboratory shaker to homogenize samples before reading.
A modern digital reader must offer an excellent compromise between precision, ergonomics and adaptability to your current and future experimental needs.
Applications of plate reader in biology and life sciences
The plate reader is ubiquitous in many scientific disciplines:
- Cell biology : assessment of cell viability, cytotoxicity, cell proliferation.
- Molecular biology : quantification of DNA, RNA, enzymes and proteins.
- Immunology : enzyme-linked immunosorbent assays (ELISA), detection of antibodies or antigens.
- Pharmacology : high-throughput screening of active compounds.
-
Food industry : detection of microbial contaminants or toxins in food.
Thanks to its versatility, it is suitable for basic research laboratories as well as industrial or hospital laboratories.
