The Zetasizer Sample Assistant significantly enhances your Zetasizer Advance system utilization by minimizing the downtime between samples, ensuring that your laboratory operates at peak efficiency without any compromise to data quality. This tool integrates seamlessly with your existing methods, simplifying the process of method transfer. If you find yourself needing to develop a new method, you can easily create one using the standard procedures in the Method Builder.

Furthermore, the Zetasizer Sample Assistant supports the use of multiple methods, even if they are all on the same sample tray, allowing for versatile handling of various tests concurrently. This versatility is paired with a user-friendly workflow that guides users through regular maintenance tasks effortlessly. By implementing these features, the Zetasizer Sample Assistant not only streamlines your laboratory operations but also boosts overall productivity and reliability.
