NEPHELOstar Plus – Microplate reader
The world’s first and only laser-based nephelometer microplate meter was developed to meet the high throughput demand for rapid screening of solutes. NEPHELOstar ® Plus detects insoluble particles in liquid samples by measuring front-scattered light and can be used for turbidity measurement, drug solubility screening, protein binding kinetics, microbial growth and petroleum process control.
