Magsphere

Magsphere Inc .很高兴为医疗和科学团体提供高质量的单分散聚苯乙烯乳胶粒子(也称为均匀乳胶粒子、乳胶纳米粒子和单尺寸乳胶粒子(微粒))的内部制造。
近30年来，我们的产品一直用于研究和商业诊断应用。通过与我们的客户直接合作，我们自豪地提供高质量的单尺寸乳胶纳米球和微球，以及开发成功的颗粒产品所需的技术支持。我们的产品可用作NIST可追溯颗粒尺寸标准、FACS(荧光激活细胞分选)标准，以及载玻片凝集试验(乳胶凝集试验，如CRP和HCG)、侧向流动快速试验和颗粒增强浊度和浊度免疫测定。我们的精密微珠也被用作液晶显示器的间隔，以控制细胞间隙。
我们可以在50至100毫升批次的特殊乳胶粒子、乳胶微球、磁性粒子、荧光微球或任何未列为标准产品的聚合物粒子中进行定制合成。为了满足您的大规模生产，我们在5升至150升的树脂反应器中生产可再生胶乳。我们可以与您的研究团队合作，根据您的需求按比例增加定制批量的微球或纳米球。
