App Note: Scale to 500L with ≥13% recovery increase​

Repligen, in collaboration with Forge Biologics conducted a case study where  AAV capture purification step was scaled from 1L at PD to 500L at pilot scale. The results  demonstrated an overall recovery increase of ≥13% with no increase in impurities.​

Learn How

every drop counts

Innovative valve block technology eliminates dead legs

Repligen valve blocks support consistent flow dynamics from mixing valve to column.

Traditional valves

Hose barb connections create dead legs and increase hold-up volume across the flow path.

Zero-dead leg valve block technology

Injection molding and overmolded connections  at critical junctions eliminate dead legs and decrease hold-up volume.

  EVERY DROP COUNTS

Low hold-up filter and sensor solution replaces  bubble trap

Traditional bubble trap​

Up to 500 ml of hold-up volume can uncontrollably disrupt gradient, causing back mixing and dilution, harming reproducibility and recovery.

Repligen filter and level sensor solution​

  • Use of a filter minimizes hold up volume helps maintain gradient control and promotes higher recovery​
  • A level sensor coupled with the filter enables the automation of  air release
  EVERY DROP COUNTS

Over-molded connections reduce shear stress

Hose barb connections create dead legs and increase hold-up volume across the flow path.

Traditional technology

Traditional solutions utilize  hose barbs, zip ties and individual valves at tubing junctions causing excess shear stress to the product as inner diameter narrows and flow dips into significant dead legs.

Repligen Technology

The consistent ID of overmolded connections coupled with injection molded tubing and valve block hardware at critical junctions eliminate dead-legs, minimize shear stress and protect product integrity.

ONE DESIGN SCALED PERFECTLY

Innovation and precision engineering at four different sizes

To remove process scale-up challenges, KRM™ Systems are part of one family built off of one design. The goal is to streamline scale-up from 1 L/h to 3600 L/h.

  • One optimized flow path design
  • Consistent hardware, including pumps
  • Identical user experience

  SINGLE-USE AND SIMPLIFIED

Precise buffer control enables maximal product recovery

Precise process control of buffer composition, optimal flow path and hardware design unlock accurate gradient control and improved recovery.

 SINGLE-USE AND SIMPLIFIED

Error-free installation in minutes with pre-assembled flow paths

ProConnex® Flow Paths, pre-assembled and specific to the KRM™ System, are intuitively designed for simple, mistake-free installation. All system sensors are pre-calibrated and assembly is done in minutes with no confusing instructions.
