Particle Micronizing and Disaggregation
The Covaris system has been demonstrated to offer significant advantages in compound formulation work over mechanical blade and probe based sonicators. These suffer from reproducibility issues and can transfer large amounts of heat into the product causing potential degradation.
The Covaris AFA technology allows the rapid disaggregation micronizing of compound formulations and slurries, and improving particle distribution data, (please see data below). AFA can operate in batch and in continuous flow mode for large volume processing.
Impact of AFA on Inhaled Programs
Covaris-dispersed non-micronized suspensions are very effective in micronizing drug suspensions to:
- Allow in vivo testing with much smaller (mg) amounts of drug substance.
- Permit testing without scaled-up re-synthesis.
- Avoid repeated studies.
- Reduce animal use.
- Impact on the throughput of inhaled lead optimization programs for the future.
- Reduction of poorly-soluble compounds for oral programs.
- Conventional micronizing requires more drug than if using Covaris AFA.
