ERWEKA USP 4 Systems

ERWEKA offers three different USP 4 systems, which can be adapted individually to your personal needs.

USP 4 Stand-Alone System

The ERWEKA stand-alone flow-through cell system is perfect for performing simple release tests with manual sampling. Therefore, the new flow-through cell tester DFZ II offers in a system with the ERWEKA piston pump HKP 720 and the ERWEKA heater DH 2000i an easy entry into testing with USP 4 systems for a small budget.

USP 4 Open Offline System

The open ERWEKA offline flow-through cell system is the perfect solution for testing poorly soluble products that need unlimited amounts of fresh media to dissolve. It also offers the opportunity to quickly and easily exchange media with different pH-values within one test run and is thus perfectly suited for IV/IVC testing.

USP 4 Closed Offline System

The closed ERWEKA offline flow-through cell system is excellently suited for testing low-dose formulations with sustained release (e.g. implants). It allows performing comprehensive long-term dissolution tests with small media volumes.

Each system comes with our new USP 4 Flow-Through Cell DFZ ll, that features innovations such as the new cell design with increased leak-tightness and the optimized tubing system.
