Handling Instructions – 3D Serpentine Mixer Fluidic 1079

Many microfluidic systems require rapid mixing of different fluids within microchannels. While diffusion can be an effective mode of mixing in microchannels with predominantly laminar flows, it often requires prolonged mixing times and/or ideally increase of interfacial area.
Introducing chaotic (but still laminar) flow patterns can aid mixing efficiency in microchannels. This strategy becomes even more important when mixing solutions with particularly low diffusion coefficients. The 3D serpentine mixer has been developed especially to address this challenge in microfluidics. It is the perfect tool to investigate fast and efficient passive micromixing of up to three liquids.

Handling Instructions – Diffusion Mixer Fluidic 186

As flows in microchannels are usually laminar, mixing of liquids at microscale is a challenge but can be tackled using various approaches. One of the simplest methods for effective micromixing is to increase the interfacial areas between the fluids. Diffusion will cause the transfer of molecules through the interfacial area.
microfluidic ChipShop‘s diffusion mixer with its 217 mm long channel that enables a prolonged co-flow of fluids, makes use exactly of this principle.

Droplet generation

Droplet generation using microfluidics has attracted a lot of interest due to the ability to produce highly monodispersed droplets with high frequency. The generation of droplets is based on the use of two immiscible phases: continuous phase (medium in which droplets flow) and dispersed phase (the droplet).
