[RASMB] capillary viscosimeter

[HGSR (Holger Martin Strauss)]

Hello everyone,

We've recently ventured into measuring viscosities. We use a capillary viscosimeter Lovis 2000 ME from Anton Paar and have observed several times that high concentration protein solutions stick to the (glass) capillary, after rinsing and scrubbing. We then treat the capillary with piranha solution. This is annoying and cumbersome and we haven't yet found a way to avoid/reduce of protein sticking to the surface. But maybe someone of you has?

Best wishes, Holger
