Analytical Weighing
High-precision gravimetric determination for analytical workflows.
Application Overview
Analytical weighing is a critical step in many laboratory workflows where precise and reproducible determination of sample mass is required. Unlike process control weighing, analytical weighing focuses on high-precision mass determination for defined sample preparation and quantitative analysis.
The Lab-Bot can be equipped with a dedicated analytical weighing unit designed for enhanced measurement stability and electrostatic compensation. This configuration enables weighing accuracy down to 0.1 mg and ensures reliable gravimetric determination for sensitive analytical applications.
For statistical validation, the system allows multiple consecutive weighing cycles. The number of measurements can be predefined, enabling automated averaging and improved measurement reliability without manual intervention.
Analytical weighing can be combined with optional decapping to determine the net weight of uncapped tubes and ensure accurate sample preparation prior to dilution, digestion or chromatographic analysis.
By automating high-precision weighing and integrating it directly into structured laboratory workflows, Analytical Weighing reduces operator influence, improves reproducibility and creates a reliable foundation for downstream analytical processes.
