Automated Block Digestion and Sample Dilution

DURABLOCK Auto

Description

The DURABLOCK Auto Sample Digestion System is designed to alleviate all of the mundane, tedious, and manual processes associated with mercury and metals sample preparation. It increases the accuracy and precision of reagent additions, final dilutions, and aliquot transfers. Technician safety is increased by significantly reducing the manual handling of concentrated acids.

The DURABLOCK Auto simply automates your current laboratory methods. Load your samples and the DURABLOCK Auto does the rest. When the instrument is finished, the samples are ready for your analyzer (ICP, ICPMS, AA, Mercury Analyzer, etc.).
