The Accumix Dry Acid Dissolution system is an automated acid mixer designed to simplify acid batch preparation and acid concentrate transfer to tanks for dialysis clinics.

Next-generation innovation includes automated batch verification, radio frequency identification (RFID), and more

The Accumix Dry Acid Dissolution System was purposefully designed and integrates scanning, sensing, and record retention technology.1

Streamlines daily workflows and reduces multiple manual tasks

The low powder-entry point allows for the ergonomic handling of heavy powder boxes.2 A touchscreen panel leads the operator step-by-step through the acid mixing process.3 Built-in sensors facilitate the filling and rinsing and enable the automation of associated interaction steps.3,4 Prompts and updates displayed on the touchscreen throughout the mixing process aim to keep the operator engaged.1,4 Accumix is the first dry acid mixer in the US to automatically determine specific gravity at the end of batch preparation.4

Reduce the potential for human errors during batch preparation

During the batch preparation process, the barcode scanning facilitates data matrix entry. The system matches data against the entered prescription, checks expiration dates, and alerts operators of errors.5

Sensing technology determines the specific gravity of the solution. When the acid solution passes automated verification, the system allows transfer to the corresponding RFID-enabled storage tank or jug fill wand.6

Electronic record retention

Regulatory bodies require record-keeping for quality assurance of hemodialysis devices.7 Accumix mixer electronically captures batch production records and disinfections that may replace the need for paper documentation.8


Additional Benefits:

Versatility: One system prepares 99 and 132 gallons of acid1
Compatibility: Fits through standard doors, facilitates logistics and installation1
Acid Waste Reduction: Eliminates the purge of 3.5 gallons of acid in the transfer hose*
