Aquamarijn Emulsification module

Description

Aquamarijn offers microsieves optimized for emulsification with hydrophobic or hydrophilic coatings for making WATER in OIL or OIL in WATER emulsions respectively.

A cross-flow module made of stainless steel is available. For emulsification with strong solvents, we offer perfluoro elastomer (FFKM) O-rings. Solvent-resistant glue will be used to mount the chip onto a disc mount. Altogether, this makes the module fully solvent-compatible.

The microsieve membrane emulsification process generates monodisperse droplets by dispersing one fluid into a second, immiscible fluid through a precise microsieve. Thanks to the homogeneity of pore size, every droplet generated by the microsieve membrane is the same. In addition, hydrophobic or hydrophilic coatings for making WATER in OIL or OIL in WATER emulsions respectively, advances and stabilizes the process of emulsification. Altogether this results in highly uniform, reproducible and size-controlled droplets. The droplets can be transformed into particles after an appropriate solidification step.

In principle, the size of the droplet will be about 4 times larger than the width of the slit chip. It means:

o Slit chip 2×20 ⇒ ~ 8µm droplets

o Slit chip 3×30 ⇒ ~12µm droplets

o Slit chip 5×50 ⇒ ~25µm droplets

Additionally, membrane emulsification also can be performed with a low porosity membrane. In this case, the droplet size will be determined by the flow rate of the continuous flow. Contact us for technical support.
