Thanks to their colorless, odorless, and biocompatible properties, fluorinated oils are widely used in microfluidics for droplet applications. Fluo-Oil 40, based on Fluorinert 40, and Fluo-Oil 7500, based on Novec 7500, are well suited for water-in-oil emulsions as a stable carrier phase. Fluo-Oil 135 and Fluo-Oil 200 are alternatives to Fluo-Oil 7500 and Fluo-Oil 40, respectively.
Available in bottles of 10 mL, 20 mL, 50 mL, and 100 mL.
General
We have chosen these oils for their high stability and wide chemical compatibility. Fluo-Oil 40 and Fluo-Oil 7500 are used in a wide range of applications: cell sorting, protein studies, research on living cells, or droplet encapsulation to name a few. Their permeability to gases makes experiments with living cells possible.
Fluo-Oil 40 contains FC-40TM from 3M company, and Fluo-Oil 7500 contains NovecTM 7500 from 3M company. Fluo-Oil 135 and 200 are alternatives with similar properties to respectively Fluo-Oil 7500 and Fluo-Oil 40.
Use Fluo-Oil 40 to dilute FluoSurf in FC-40, and Fluo-Oil 7500 to dilute FluoSurf in HFE 7500. FluoSurf is a high-performance surfactant specifically formulated to get highly stable and monodisperse emulsions. To find out more about oil/surfactant compatibility, the experts of Darwin Microfluidics invite you to consult their review "Choosing the best oil and surfactant for droplet generation".
Fluo-Oil being fluorinated oils, we recommend using a fluorophilic coating in your microfluidic channels. A standard hydrophobic coating can also work.

Specifications
Fluo-Oil 40 is slightly more viscous than Fluo-Oil 7500, so the droplet generation speed with Fluo-Oil 7500 will be a bit faster than with Fluo-Oil 40, and also closer to water. Besides this difference in viscosity, the two oil types have quite similar properties.
