ControLyo Nucleation on Demand

By inducing simultaneous nucleation of all the vials inside the freeze dryer chamber, our ControLyo™ technology can deliver improved product uniformity, quality and yield, while reducing cycle times by up to 40%.

Direct Oxygen Injection

Direct Oxygen Injection for Fermentation

Using direct oxygen injection and proprietary mixing technology, POL can help overcome dissolved oxygen limitations and expand the productivity of aerobic microbial fermentation by up to 65%.

Reactor Cooling

Our non-freezing direct and indirect cooling equipment provides the rapid cooling and precise temperature control required for reaction and process optimization. By harnessing the cooling power of cryogenic nitrogen, our highly efficient systems (> 95%) eliminate the need for complex, multi-stage mechanical refrigeration. Customers have experienced reduced operating costs, less maintenance requirements and increased peace of mind.
