BioTek ELx808 Absorbance Microplate Reader with UV-Vis Detection and 4-Zone Incubation Option
Product Description
The BioTek ELx808 Absorbance Microplate Reader is a versatile UV-Vis spectrophotometer designed for high-throughput quantification of biomolecules in 96-well microplates. It features a tungsten halogen light source and photodiode detector, covering a wavelength range of 380–900 nm on the base model and 340–900 nm on the ELx808IU variant with UV capability. This reader supports multiple read methods including end point, kinetic, and linear scanning, enabling precise kinetic ELISA assays and other quantitative absorbance measurements.
Key technical specifications include:
- 96-well plate format compatible with standard assays in biotechnology, cell biology, molecular diagnostics, and neuroscience research.
- Wavelength filtering via a 6-position filter wheel with up to 5 filters supplied, ensuring spectral selectivity and minimizing channel cross-talk.
- Optical performance with dynamic range 0–4.0 OD, resolution of 0.001 OD, and high accuracy (<1% OD at 2.5, <2% at 3.5), critical for reliable bioassay quantitation.
- A fast kinetic read speed of 8 seconds for a full 96-well plate, optimizing workflows in bioprocessing and clinical diagnostics.
- Optional 4-zone temperature control with incubation up to 50 °C (ELx808IU model), essential for live-cell assays and controlled enzymatic reactions.
- Onboard diagnostic self-tests and calibration via test plate to maintain instrument performance and compliance with validation protocols.
- Integration with Gen5 Software, providing advanced data analysis tools such as transformation formulas, assay control, and validation features tailored for molecular biology and biomanufacturing processes.
Physically compact (16 x 14 x 7 inches) and lightweight (20 lbs), the ELx808 supports efficient laboratory space utilization. Its robust design minimizes edge effects and evaporation via a heated carrier, enhancing assay consistency.
Widely used in biotechnology applications including molecular cloning workflows, synthetic biology research, and biopharmaceutical production pipelines, the BioTek ELx808 is optimized for absorbance-based assays in live-cell imaging, fluorescence analysis, and clinical biomarker quantification. This microplate reader is a critical tool for researchers demanding precise, reproducible, and high-throughput absorbance measurements in diverse biomedical and agricultural domains.
Included accessories typically comprise the absorbance reader with validation reports, Gen5 software on a Windows platform, communication cables, user manual, and power cords, backed by standard warranty support.
