The solution
Accurate means counting cells
BactoBox® counts the bacterial cells in your sample, one at a time, and measures their size from the same reading. Two minutes, on the bench, no plates and no stains.
The count is your growth curve. Cell size tells you what state the cells are in.
Cells/mL is an absolute unit that holds across strains, media and conditions.
Use cases
Built for upstream microbial process development
Bacterial cultivation and fermentation, batch and fed-batch, at development and pilot scale.
Media screening and process optimization
Compare process conditions based on real growth.
Transfer and harvest timing
See exactly when your culture reaches the right growth phase.
Growth dynamics
Resolve precise growth dynamics across process conditions with true kinetics data.
