ezfill 4500
Dissolution Media Preparation Station
The ezfill 4500 is compact, transportable, and easy-to-use. The unique integration and control of critical functions like heating and vacuum degassing allow the unit to prepare and accurately dispense media in less than 90 seconds* for volumes as large as 1000 mls containing up to 2% surfactant. The system is user programmable and volumes are settable between 250 mls and 1000 mls in 5 ml increments. For programmed volumes of less than 500 mls the unit will automatically employ the MDC or Multiple Dispensing Cycle mode. The MDC simultaneously processes aliquots of media in multiples equal to the maximum volume of 1000 mls per cycle.
The MDC mode significantly reduces the average time to dispense by taking advantage of the ezfill’s ability to batch process.

The ezfill 4500 offers tight controls over key volume and temperature parameters with accuracies of ±1% for volume and ± 2°C for temperature, meeting compendia requirements. The high precision glass vacuum chamber and piston are used to create the conditions for fast and effective de-aeration and media dispensing where up to 3 ppm of dissolved oxygen can be removed. Because an analytical balance and vacuum pump are not required to prepare and dispense media, the ezfill 4500 is compact, light weight and easily relocated around the dissolution laboratory.
