The Brabender Void Volume Meter provides you with a rapid, simple and cost-effective alternative to the oil absorption process for determining the void volume of structured solids (e.g. carbon blacks, acetylene black, silica materials). Auxiliary substances are not required. For quality control in incoming and outgoing goods as well as for product development, production monitoring and management, the Void Volume Meter only requires small sample quantities.
With the hydraulically operated die, a very high compression rate is achieved and, compared to oil absorption measurements, a higher measurement frequency is reached, leading to a higher efficiency. A precision scale (optional) is directly linked to the device and communicates with it. Calculating the difference between the measured and the theoretical volume gives the remaining pore volume (VV). The pressure is increased continuously in the sample chamber according to a specified compression rate until the freely editable pressure value is achieved. More information
