Meet Affipump

A High Accuracy Dual-Syringe Pump

The Affipump stands as the pinnacle of syringe pumps, offering unparalleled accuracy, reliability, and precision for flow-based analysis. Its precise flow rate control ensures smooth liquid flow with minimal pulsation, solidifying its reputation as the ultimate choice for flow-based analysis using our P4PRO device. 

Some unique features include: 

  • Ultra-low pulsation 

  • High speed control

  • Extended flow rate range from 5 nl/s up to 5 ml/s.

  • Can be operated individually or in tandem


Introducing the ultimate tool for precision analysis: P4PRO and Affipump. With its advanced technology, this versatile device offers unparalleled control and flexibility, allowing users to easily switch between static and flow analysis modes with the addition of the Affipump. Its high accuracy dual-syringe pump provides a wide range of flow rate options, while its ability to perform both static and flow-based analysis makes it a powerful tool for a variety of applications. For example, you can condition and prepare your immobilization in static mode and then seamlessly switch to flow for kinetic analysis. Whether you need individual or multi-channel analysis, the P4PRO and Affipump delivers real-time, inline controls and unbeatable performance.
