Puromill™ 研磨介质

PuroMill™药用级先进工艺的研磨介质可帮助您提高研发成品质量。它是一种低密度聚合物研磨介质,能够制备小于100 nm的纳米颗粒,这些纳米颗粒不会因可萃取、可浸出和磨损而受到污染。使用传统或新型铣削设备进行高剪切铣削。

PuroMill™通过先进的纳米颗粒研磨技术实现溶解度增强。

  • 提高药物化合物的生物利用度
  • 高纯度聚合物研磨介质
  • 在cGMP认证、FDA检查的工厂生产
  • 药物/生物制药制剂理想的研磨材料
  • 生产小于100 nm的药物纳米颗粒,以增强溶解性差的药物的吸收
  • 实现高效生物细胞破坏,无需研磨相关污染
  • 尺寸为50–1000µm,用于优化药物制剂的研磨性能
  • 在FDA注册的药品主文件(DMF文件)
