NEPHELOstar Plus

The World's First and Only

Microplate Nephelometer

Overview

Laser-based microplate nephelometer for light-scattering and turbidity measurements

The NEPHELOstar® Plus microplate nephelometer was developed to meet high-throughput demands for fast compound solubility screens. It detects insoluble particles in liquid samples by measuring forward scattered light and can be used for turbidity measurements, drug solubility screening, protein binding kinetics, microbial growth, and petroleum process control.
