Weighing and Dispensing Containment Isolator (WDCI)
The Esco Weighing and Dispensing Containment Isolators (WDCI) are advanced containment systems providing controlled negative pressure environments to maximize personnel protection during weighing and dispensing of potent compounds.
Esco WDCIs’ provide standard configurable designs that are able to adapt to various weighing and dispensing quantities and accuracies.
Fully welded single-piece SS316L internal chambers with rounded coved corners
Pressure tested to ISO 14644-7
Inflatable antibacterial, USP Class VI compliant and food grade FDA approved gaskets providing both proactive and reactive sealing
Safe change glove system allowing change of gloves whilst maintaining a contained system
Integrated anti-vibration granite platform for analytical balance placement
Integrated automated pressure decay testing
Clean interior and exterior finishing
Safe change filters to allow in-process filter replacement
Lighting external to isolator chamber for ease of servicing and process chamber cleanliness
Integrated automated height adjustment providing 280mm of motion for ergonomic comfort
