PKL Chromatography Systems for Process Development

The suite of PKL bench-top chromatography systems is designed for rapid method and process development across a broad spectrum of biotherapeutics such as proteins, peptides, plasmids and viruses. The result is a blend of unique advantages and user features which are unmatched in the industry.

The high dynamic flow range of the systems enables suitability for all formats of chromatography: conventional column, expanded bed, and membrane chromatography. Other key features include powerful, easy-to-use Windows-based software, an active air trap, a multimode detector and a 100:1 pump-turndown ratio.

Developed from proven systems, with many years experience and a large customer base, PKL systems are also part of the Pall family of PK chromatography systems. The PK software wizard enables easy transfer of optimized methods from the PKL systems to process-scale PK chromatography systems. This allows optimum flexibility for changing process demands.

Features
