艾美捷科技代理Nexcelom品牌。

2003年，Nexcelom的创始人推出了CP2，这是一种辅助手动细胞计数的方便工具。Nexcelom的创始人兼首席技术官JeanQiu博士说，“NIH的某位客户曾要求我们‘消除显微镜计数’。

为此，我们发明了CellometerAutoT4，用于测量细胞浓度和活力。”自那时起，Nexcelom扩大了产品范围，升级了系统功能，并优化了适用的方法，使研究人员能够分析所有细胞类型，

包括小细胞和原代细胞。凭借先进的专有技术，Nexcelom是细胞分析中基于图像的细胞计数的领导者和创新者。世界各地的科学家在学术和政府研究机构、生物技术和工业环境中使用

Cellometer，Cellaca和Celigo仪器进行细胞定量、分析和基于细胞的检测。Nexcelom图像细胞术和细胞分析解决方案被集成到生命科学的广泛工作流程中。
