Why use a micro fluidic mixer?

Microfluidic chips often operate laminar flow regime which are not ideal circumstances for mixing of liquids. Also, not all combinations from liquids mix as easily. This can result in the need for long mixing lengths or ineffective mixing. Mixing is sometimes also applied to create nanoparticles; such processes use chemical interaction between liquids that result in particle generation at liquid contact surfaces.  Micro mixers increase such liquid interaction and offer a relatively stable mixing condition which results in more controlled liquid interaction.

What are the advantages?

By adding mixing structures to a microfluidic setup or design the chip’s footprint can be reduced compared to incorporating just a long channel. Also, achievable mixings can be improved, which is often beneficial for results in subsequent analysis steps.

Nanoparticles with a much more contestant size distribution are created due to the highly controlled and predictable liquid interaction.

Double F Mixers - fully transparent

  • Ideal for: Effective mixing along the length of the mixing channel.
  • Mechanism: Split-and-recombine flow channels with multiple splits create parallel diffusion planes.

  • Fully transperent: The mixers are wet etched for optimal sight from both the top as bottom surface.Our etching process create ultra smooth surfaces.

Interfacing
The recommended interfacing tool is our Fluidic Connect Pro chip holder for chips in a cartridge.  In addition you will need a Connection Kit. The chips are also compatible with the Fluidic Connect 4515 chip holder.

Customer Questions
What's important in selection of a suitable microscope objective?
An inverted microscope is recommended for observing flow in microfluidic chips, as most observation surfaces are located on the bottom (non-inlet) side. A key parameter in selecting a suitable objective is the working distance. For thin-bottom chips, the working distance is less critical, as the distance to the channel is typically below 175 µm. However, it is still recommended to minimize the size of the objective itself where possible, to allow more space for movement within the holder. For chips with regular (thicker) bottoms, the working distance becomes a critical factor. Most standard objectives are designed for use with a #1.5 cover slip, which has a thickness of only 170 µm. However, the bottom thickness of typical microfluidic chips is usually in the range of 400–900 µm. Therefore, long working distance objectives—often referred to as non-cover glass objectives—are more suitable. Whenever possible, we recommend using dry objectives, as they simplify the setup and eliminate the need for immersion media. In many cases, it is feasible to use the edge of the channel or another well-defined feature as a reference point for manual size correction. This approach can reduce the need for optical corrections provided by the objective itself.
What locations should be used for making the fluidic connections with the mixer chips?
To mix the two liquids, connect their tubes to locations 2 and 4. The resulting mixture can be collected by attaching a tube to location 7. Location numbers are indicated on the holder.
Do I really need a chipholder to connect my tubing with the chips?
We highly recommend using our Fluidic Connect Pro chip holders, along with a connection kit, to securely connect the tubing to the chip. The chip holder presses an elastomeric component against the glass chip, creating a reliable seal between the tubing and the chip. The use of glue is not advised, as capillary action may draw the adhesive into the chip, potentially causing damage.
What pump system do you recommend for mixer chips?
Mixer chips offer flexibility within various pumping systems and are compatible with syringe, peristaltic, and pressure-based pumps. However, it's important to consider chemical compatibility when selecting your setup.
