VROC®动力粘度计可根据剪切速率或温度来完全表征粘度。同时，RheoSense的粘度计为在复杂液体（即非牛顿）生产中必不可少的宽动态范围内的完整的广泛粘度表征提供了一种经济高效的替代方案。

VROC®initium可在受控的剪切速率和温度下提供无人值守的粘度测量。我们最先进的粘度计功能：

高精度的动态粘度测量
与HPLC 40样品瓶和96孔板的兼容性
自动样品加载，测量和清洁

与传统的粘度计和流变仪相比，RheoSense的微流控设备具有以下优势：

每次测量仅需几微升
允许表征牛顿流体和非牛顿流体
实现高剪切速率而没有流动不稳定
防止样品蒸发和污染
简单的流通设计可提供高吞吐量

科学原理
测量池或“芯片”包含一个矩形的狭缝流动通道，该通道由硼硅玻璃制成，具有均匀的横截面积。样品以恒定的流速通过流道注入，在流道中，安装在基座内的多个压力传感器监控从入口到出口的压降。压降与边界壁处的剪应力相关。剪切速率和剪切应力与矩形缝的几何形状和流量直接相关，从而可以进行粘度测量。
