Vivaspin 2,0.2µm PES,25件

Vivaspin® 浓缩器属于一次性超滤装置,可浓缩生物样品。Vivaspin® 2可放入适合15ml离心管的水平转子或固定角转子中高效使用。专利的垂直膜设计和薄通道过滤室(US 5,647,990)可最大限度地减少膜污染,实现高速浓缩 - 即使是含有大量颗粒物的溶液也不在话下。Vivaspin® 2兼具经典版Vivaspin®产品的速度与较低的内部表面和膜面积,即使是极低浓度的稀释溶液,仍可实现出色回收。Vivaspin® 2 可提供三种不同膜材质:PES、醋酸纤维素膜或Hydrosart®膜,具有灵活性,可实现工艺优化。Vivaspin® 2的另一项特征是可选择使用移液器直接从浓缩器底部内置的死端结构中吸取并回收浓缩液,或者将浓缩液反转离心到回收帽内。这两种方法均可使浓缩液达到近乎完全回收。

  • 三种不同膜材质可供选择
  • 高渗余物回收率> 90 %
  • 垂直膜设计,适用于超快浓缩
  • 兼容通用转子
  • 采用死体积设计,安全浓缩样品
  • 使用移液器回收浓缩液,比较方便
  • 可选反转离心,提高浓缩回收率
  • 浓缩管上标有刻度,方便阅读/监测
