对于较大量生物样品的压力浓缩，Vivacell 250浓缩器提出了全新的概念，这种浓缩器与带搅拌装置的样式浓缩器相比，具有许多优点。Vivacell 250样品处理量为50ml-250ml，既可放在工作台上，也可静置于冰箱中，又可放在摇床上快速浓缩，同时降低了剪切力的影响。Vivacell 250独特的滤膜组件，垂直膜设计，降低污染。独特的锥形死端结构设计允许样品被浓缩至1ml以下。各组件容易安装，换膜也只需数秒钟时间，操作简便。通过有刻度的观察窗可以实时观察浓缩情况。
- 操作简单
- 高通量聚醚砜膜
- 垂直膜设计，超高速浓缩
- 高回收率>90%
- 组件可重复使用，只需更换膜
速度需求！
既可放在工作台上或冰箱中静置浓缩，又可放在摇床上快速浓缩。独特的锥形死端结构设计允许样品被浓缩至1ml以下。振荡产生的涡流避免了滤膜因浓差极化而阻塞，同时极大地降低了剪切力。而剪切力在带搅拌装置的杯式超滤浓缩管中是难以避免的。组件安装和换膜只需数秒，操作简便。快速连接配件和简单的旋盖进一步提高易用性。
