All Praesto® chromatography resins are manufactured using our patented Jetting technology. It's faster, more environmentally-friendly, and produces consistent beads with a uniform particle size distribution.

This results in shorter lead times and faster mAb processing, whilst contributing to your sustainability goals.

Supply chain benefits

Purolite's goal is to secure supply, enable lot-to-lot consistency and minimize the impact of change.

In addition to our industry-leading security of supply and business continuity plans, Jetting technology has significant advantages for your supply chain.

Other agarose manufacturing technologies require a screening step to filter out beads that are too large or too small to be used in process. This is one of the most time-consuming steps in agarose resin production. The mechanism of Jetting technology eliminates this step completely, significantly reducing our lead times and improving your on-time delivery reliability.

With the shortest lead times in the industry, Purolite have been able to support major global biopharmaceutical manufacturers during the most challenging global conditions.

Lot-to-lot consistency
Jetting technology gives Purolite precise control over bead size and distribution. Praesto beads are uniform, meaning unrivalled lot-to-lot consistency, and minimal variation batch to batch. 

Multiple manufacturing locations
We have ISO-accredited Praesto Jetting facilities in the UK, which conform to global quality standards. Purolite is the leading the way in improving the security of supply of agarose-based resins as the first supplier to commission production facilities on multiple continents.

Jetting technology is a far more environmentally-friendly manufacturing process than alternative technologies. It consumes significantly lower volumes of water and solvent (such as toluene), and generates less CO2. 

Process Benefits

Praesto chromatography resins contain the only uniform agarose beads on the market. This gives Praesto resins unique performance benefits when utilized in process. 

  • Faster mass transfer kinetics
  • Reduced column packing failures
  • Improved resolution
  • Higher flow velocities
  • Longer lifetime
