Double Emulsion Production Station

The Fluigent double emulsion production station is a robust and complete system for producing outstanding monodispersed double emulsion in one single device.

Its performance is coming from the combination of Fluigent’s LineUP microfluidic pumps and the RayDrop device, a breakthrough technology for high monodispersed and stable double emulsion.
