NEPHELOstar Plus
光散射和浊度检测的激光微孔板分析仪
NEPHELOstar® Plus 是全球首款基于激光技术的微孔板浊度分析仪，专为高通量复合物溶解度筛选而设计。
该系统通过检测前向散射光信号，定量分析液体样品中的不溶性颗粒，可用于浊度测量及多种相关应用，包括药物溶解度筛选、蛋白结合动力学研究、微生物生长监测以及工业过程控制（如石油加工）。
NEPHELOstar Plus
NEPHELOstar Plus 配备高强度激光二极管光源，是一款基于激光散射原理的微孔板浊度分析仪。与传统基于透射光密度（OD）的检测方法相比，该系统通过测量前向散射信号实现分析，灵敏度提升约 30 倍。
凭借高速检测性能、高灵敏度与良好的方法灵活性，NEPHELOstar Plus 可将激光散射浊度分析拓展至更广泛的微孔板应用场景。
