Magsphere Inc .很高興為醫療和科學團體提供高質量的單分散聚苯乙烯乳膠粒子(也稱為均勻乳膠粒子、乳膠納米粒子和單尺寸乳膠粒子(微粒))的內部制造。
近30年來，我們的產品一直用于研究和商業診斷應用。通過與我們的客戶直接合作，我們自豪地提供高質量的單尺寸乳膠納米球和微球，以及開發成功的顆粒產品所需的技術支持。我們的產品可用作NIST可追溯顆粒尺寸標準、FACS(熒光激活細胞分選)標準，以及載玻片凝集試驗(乳膠凝集試驗，如CRP和HCG)、側向流動快速試驗和顆粒增強濁度和濁度免疫測定。我們的精密微珠也被用作液晶顯示器的間隔，以控制細胞間隙。
我們可以在50至100毫升批次的特殊乳膠粒子、乳膠微球、磁性粒子、熒光微球或任何未列為標準產品的聚合物粒子中進行定制合成。為了滿足您的大規模生產，我們在5升至150升的樹脂反應器中生產可再生膠乳。我們可以與您的研究團隊合作，根據您的需求按比例增加定制批量的微球或納米球。
