Each microfluidic block is approximately 16mmx16mm. Produced from molds using highly precise 3D printing technology, the parts offer good feature resolution while reducing cost. Check back frequently as more designs are incorporated.
Input/Output Blocks
One Direction Single Input Block
The one direction single input block allows for a single input of fluid in one direction to be introduced to the microfluidic device. It is an important but basic requirement to introduce fluid into the microfluidic device.
Two Direction Single Input Chip
The two directions ingle input block allows for a single input of fluid to be directed in two opposing directions. This chip is particularly useful for assembling a flow generated droplet generator chip using other components listed below. See applications in the side panel for more ideas and uses.
One Direction Double Input Block
The one direction double input block allows for two input fluids to be mixed together into one channel. However, if thorough mixing is desired this chip should be used in conjunction with the passive mixing chip listed below.
Basic Configuration Blocks
Straight Channel Block
The straight channel block is used to configure microfluidic chips to create custom designs. This particular block is well suited for examining diffusion of two dissimilar miscible fluids.
Left and Right Elbow Block
The left and right elbow blocks are used to configure microfluidic chips. These particular blocks are useful for changing fluid direction 90 degrees. They are also useful for specific applications such as droplet generation. See applications in the side panel for more ideas and uses.
Intersection Block
The intersection block has several useful functions for configuring microfluidic chips. They allow for up to three input streams to be combined into one and allow for a single output stream.
Mixing Blocks
T-Junction Block
The T-junction block is used to allow for two input streams to be combined into one or to create two output streams if desired. It shouldn’t be confused with the T-junction droplet generator specified below.
Passive Serpentine Mixing Block
The passive Serpentine mixing block has one input and one output stream. As fluid passes through mixing occurs via diffusion. The channel geometry increases the travel distance, effectively increasing the contact time allowing for thorough mixing. Other designs leveraging contact area via geometry modifications are being developed.
Droplet Generator Blocks
T-Junction Droplet Generator
The T-junction droplet generator is useful for creating droplets and emulsions using two immiscible fluids. By controlling and maintaining constant flow rate, uniform droplets can be created in high output. Droplet size is controlled by altering the flow rate of the main through and through channel.
Flow Focused Droplet Generator (with and without input)
The flow focused droplet generator, similar to the T-junction droplet generator, is useful for creating droplets and emulsions using two immiscible fluids. However, for higher flow rates the flow focused droplet generator creates more reliably uniform droplets than the T-junction droplet generator.
This configuration allows for two
input reagents that pass through
a mixer to create a homogenous
mixture.
