Beckman Coulter’s Multisizer 4 provides analysts with an easy-to-use, technologically-advanced system that can solve most particle sizing and counting challenges. Implementing the Coulter Principle with Smart Technology, the Multisizer 4 ensures the repeatability and uniformity of sample analysis conditions and therefore produces reliable results.
Although the following procedures were developed to address common issues encountered when analysing subvisible particles in protein formulations, the general guidelines can also be used for applications requiring small aperture tubes. Specifically, the cleaning procedures are valuable when characterising very small particles at low concentrations.
