Previously analysing protein solutions had been impossible due to the large sample vessel incorporated in PAMAS laboratory instruments. Protein solutions and other pharmaceutical liquids are usually only available in very small sample volumes. As a consequence, PAMAS upgraded its SBSS laboratory instrument and equipped it with an optional small pressure vessel container. With the help of this new feature, small sample volumes of 1-5 ml of high viscosity liquids are now able to be analysed.PAMAS adds that the main benefit of the SBSS laboratory instrument is the integrated pressure container. This sample vessel is used to create either a high pressure or vacuum atmosphere that is safely enclosed within the locked container. High pressure is applied to transport high viscous liquids through the sensor for measurement, whereas the vacuum mode removes gas bubbles out of the sample.
