DEENA, an automated sample digestion system, fully automates the sample preparation for EPA and other laboratory methods that use hot water baths or heated blocks. In metal and mercury analysis, manual sample preparation often consists of many steps that are both labor intensive and time consuming. DEENA alleviates most of the manual sample preparation and reduces the errors associated with sample handling. DEENA has the necessary functionality to automate your sample digestion process without modifying it.
What does DEENA do?
- Improves laboratory safety
- Reduces manual handling of acids
- Increases efficiency
- Frees up technician time
- Provides consistent results
Dispensing Reagents
In addition to dispensing reagents and heating the samples, DEENA prepares calibration and spike standards, shakes the samples, inspects their color, adjusts the sample volumes after the digestion process, and records every step taken in the process.
DEENA handles up to 6 standards and 9 reagents including a dedicated reagent line for difficult solutions (e.g., KMnO4), avoiding cross-contamination. There are also 3 racks, each having a capacity of 20 samples, for ease of handling and portability. With the optional fume hood, DEENA can be placed on a bench top, freeing up valuable fume hood space.
