  • •Mass flow control of flow rates by means of a flow meter mounted after every pump 
  • •Double tube heat exchangers ensure a constant temperature in the product flow before the Chromatography column   
  • •Bubble trap and gas sensors prevent gas bubbles from entering the chromatography column 
  • •Inline filtration can be used to reduce the bioburden
  • •Pressure, temperature, conductivity, pH, UV and flow rates are recorded before and after the chromatography column 
  • Elution can be controlled by pH, UV, conductivity, volume or duration 
  • •Pressure can be controlled for chromatography columns with low operating pressures  
  • Compatible with all standard process control systems  


Possible applications

There is at least one chromatography step used for downstream purification in todays biopharmaceutical manufacturing processes. These custom made chromatography skids, executed by VOGELBUSCH BIOPHARMA, are used in a variety of processes worldwide.

Liquid filtration-steps are standard methods of modern biotechnology.

Possible applications

The various liquid filtration methods are used in a wide variety of applications in the modern biopharmaceutical industry.
Due to the process-specific development of each individual VOGELBUSCH BIOPHARMA filtration skid, they are used in various pharmaceutical plants. Some main applications are the production of antibodies, enzymes and hormones.

  • Particle separation and baterial count reduction with membrane filter elements after media-/ buffer preparation
  • Purification of fermentation solutions or crude protein solutions by means of depth filtration (disk stack modules), cassette filters or membrane filters at the start of the downstream process
  • Purification of intermediates by depth filtration
  • Bacterial count reduction with membrane filter elements for intermediate and final products
  • Nanofiltration for virus removal

Ultra and diafiltration

Concentration and changing of buffers between different purification stages

  • Skids for a large variety of membrane systems (flat screen, hollow fiber), ultrafiltration 

Ultrafiltration and diafiltration are important processes in modern biotechnological production plants. They are used for the concentration and conditioning of intermediates of the downstream process as well as for the final formulation of end products. Ultrafiltration systems from VOGELBUSCH BIOPHARMA are mobile and flexible solutions for various applications based on membrane cassette systems.
