Impingement Jets Mixing units nanoparticles (LNP, microemulsions, etc.)
IJM DuoCore NanoProducer
SYSTEMS FOR LIPID NANOPARTICLE (LNP) PRODUCTION AND FORMULATION
The number of parallel units depends on the application. Also, the number of pumps, flow meters, jets mixers and pipes can be adapted to the required conditions and scale. All IJM NanoProducers are built in a stainless steel frame on casters and are suitable for CIP cleaning procedures in pharmaceutical production. The IJM DoubleCore NanoProducer contains two parallel mixing units. Each unit consists of four pumps. Concentrated Active Pharmaceutical Ingredient (API) solution is diluted first and then mixed with the organic phase. Finally, the mixture is quenched in a third mixer. Both units can be operated independently. The IJM NanoProducer can be configured with up to eight parallel mixing units depending on the customer requirements. Each unit consists of two pumps to deliver lipid and API streams, two flow meters for flow control and one jet mixer. Depending on the configuration, the predilution of the API and quenching can be performed for the combined flow of all units in one process step outside the Impingement Jets Mixing (IJM) NanoProducer.
THE TECHNOLOGY
Impingement Jets Mixing Technology (IJM) enables the formulation and production of highquality lipid nanoparticles carrying API (e.g. for mRNA vaccines). The encapsulation process of active pharmaceutical ingredients with lipids is based on Impingement Jets Mixing Technology, where two streams collide at high velocity in a jet mixing chamber. One of the streams contains the lipids in organic solvents and the other stream the API in water.
The mixing at high velocity reduces the solubility of the lipids so that homogenous nanoparticles are formed. The quality of nanoparticles depends on the streams‘ flow stability, the mixer geometry and the fluid velocities. As a final step, the mixture is quenched to stop particle growth.
