DEVICE FOR MEASURING THE VISCOSITY OF A FLUID

The present invention relates to a device suitable for measuring the viscosity of a fluid, which device comprises on all sides surrounded channels, and a membrane suitably connected to the channels for differential pressure measurement. According to the invention, the first channel is located in a first plane and the secondchannel in a second plane, which first plane and second plane are oriented substantially parallel in relation to each other, and the membrane is located in a plane substantially parallel to the first plane. This facilitates the device to be filled with liquid without the danger of the retention of air bubbles. The device can be used as an independent viscosity meter, but may also be integrated with one or more separation techniques for particles and (polymer) molecules
