BMG Labtech NEPHELOstar Galaxy Laser-Based Microplate Nephelometer and Turbidity Reader

The BMG Labtech NEPHELOstar Galaxy is a laser-based microplate nephelometer designed for turbidity, solubility, and light-scattering measurements in native microplate formats. It supports 96-well and 384-well plates and is suitable for applications in biotechnology, pharmaceutical research, microbiology, molecular diagnostics, and bioprocessing workflows.
