Microplate Readers and Reader Accessories
Microplate readers are a type of spectrophotometer designed specifically for analyzing multiple samples in multi-well plates.
The readers detect light signals that result from biological, chemical, biochemical, or physical reactions. The signals are produced by, converted by, or transmitted through the samples and are measured by a detector. The detectors are usually photomultiplier tubes (PMT), which convert the released photons into electricity. The current is quantified by the reader’s software to produce the numerical result.
In some cases, samples are first excited by exposure to light of specific wavelengths. Filters or monochromators are used to select or restrict the wavelengths needed for emission or detection.
Single-mode microplate readers commonly measure absorbance, fluorescence, or luminescence. Multi-mode plate readers may measure absorbance, fluorescence, and luminescence with options for fluorescence polarization (FP). They may also include lasers for time-resolved fluorescence (TRF), TR-FRET, Amplified Luminescent Proximity Homogeneous Assays (ALPHA), and cell imaging.
Features may include:
- Monochromator- or filter-based wavelength selection
- Visible only or UV/Vis spectrum, fluorescence, and luminescence
- Multiple photomultiplier tubes (PMTs) for simultaneous assays
- Temperature and CO2/O2controls
- Modular design for adding functionality
Microplate readers are used for high-throughput screening (HTS), biomarker assays, nucleic acid and protein quantification, kinetics, ELISA assays, homogeneous time resolved fluorescence (HTRF) for measuring cytokines, bioluminescence resonance energy transfer (BRET), and other techniques.

Electron Microscopy Sciences Nagoette Single Counting Cell 0.5 mm
Counting cells are used to create precise volumes of liquid to enable counting of particles in a specified volume of liquid. A thick slide (glass or plastic) has an area cut into its surface that will hold precise volumes of bathing fluid. The shallow well, facilitating easy counting of contained particles. In use, a single drop of liquid is placed on the slide and a coverglass is placed on the platform providing equal and accurate subdivisions of the fluid each of which can be observed for particle counting. All complete with case and 1 pair of cover glasses. The depth of the Nageotte counting is 0.5 mm. For Liquids in Poor content.

Electron Microscopy Sciences MAC X-Ray Fluorescence Single Standard Nd
These standards are supplied as 1/4" (33 mm) diameter pressed pellets or metal foils, and are prepared from selected high purity elements and compounds to ensure interference free-spectra. They are suitable for use by experienced spectroscopists as well as staff training. Each of the pressed pellets is supported by a thin-walled aluminum cup which is protected from damage during handling and minimizes the risk of touching the standard materials (some of which are harmful).
