PIXER®

Single-Use Pump and Mixer

PIXER® is Alphinity’s single-use positive displacement pump and mixer, designed to handle today’s most demanding bioprocessing applications. Unlike traditional pumps, PIXER® manages high pressures and viscous fluids with ease without damaging sensitive materials.

At its core is an odd-numbered radial diaphragm engineered for reliable, low-shear performance, ideal for handling delicate proteins, cells, and other high-value biologics. Its unique vertical orientation with a top inlet allows direct mounting to container bottoms, enabling gravity-fed suction for instant priming. This eliminates air entrapment and cavitation commonly seen in legacy pumps.

PIXER® is versatile across the entire process stream. In upstream, it supports perfusion, cell harvest, and media circulation. In downstream, it integrates seamlessly into TFF systems, viral inactivation, and product transfer. And because it’s single-use, PIXER® eliminates cleaning, sterilisation, and turnaround delays—reducing risk, enabling faster changeovers, and ensuring compliance.
