Abstract: A viscosity measuring apparatus comprising a removable viscosity testing module and a viscosity testing apparatus. The removable viscosity testing module comprises a ducting arrangement having a first portion for receiving the fluid and a second portion fluidly connected to the first portion. The viscosity testing apparatus further comprises means for causing the fluid to pass along the ducting arrangement between the first and second portions. The ducting arrangement comprises a first reference point, and a second reference point disposed downstream of the first reference point, the first and second reference points being separated by a fixed, calibrated distance along the ducting arrangement. The apparatus further comprises detecting means for detecting when the fluid reaches at least one of the first and second reference points, and a timer for determining the time taken for the fluid to pass from the first reference point to the second reference point.

Abstract: There is disclosed an apparatus is disclosed for monitoring blood coagulation comprising a main body; a test chamber for receiving a fluid sample; and a rotor disposed within the test chamber. The rotor comprises a buoyancy chamber for reducing the apparent weight of the rotor when fluid is positioned within the test chamber.
