Cone & Plate Viscometers

The NµLine Cone & Plate Viscometer is a self-calibrating, highly adaptable ‘At-Line’ instrument designed to give you a cost effective and robust option between sensitive laboratory instruments and the lower end ‘Go-No-Go’ type viscosity measurement devices currently on the market. Readings can be taken at variable shear rates, using multiple speeds and at temperatures between 10°C to 230°C, with advance graphing outputs via the integral PC interface software, including ‘Shear Drop-Off’ the NµLine Cone & Plate Viscometer is a cross over instrument between ‘At-Line’ quality and batch control and product research and development. Its rugged design continues to meet the high demands of cutting edge manufacturing environments due to both its reliability and its performance; with many new features designed to meet the diagnostic needs of modern production standards.

Vapour Pressure

Vapour pressure is the pressure exerted by a vapour in equilibrium with its solid or liquid phase at a particular temperature. Vapour pressure increases with temperature and is a measure of volatility. Volatile material evaporates more readily than non-volatile material because it has a higher vapour pressure. If the vapour pressure of a liquid reaches that of the surrounding atmosphere bubbles of vapour will form in the liquid and the liquid will boil. Water at sea level (atmospheric pressure 100kPa) boils at 100 degrees C. This means that at 100 degrees C water has a vapour pressure of 100kPa. On top of Mount Everest the atmospheric pressure is about 26kPa. Water has a vapour pressure of 26kPa at 70 degrees C so it will boil at 70 degrees C on top of Mount Everest. So boiling point decreases with decreasing applied pressure. This principle is used in vacuum distillation.
