Translume fabricates both Microfluidic Chips and Flow Cells. These two product families have microfluidic channels with different optical characteristics, which may affect your application.
Some of the physical phenomena that we frequently encounter in our daily life do not play a significant role, nor do they seem to operate by the usual rules at the microsystem level. In this article, we look at one specific example: the mixing of liquids.
Many of our microfluidic chips and flow cells are equipped with Nanoport™ connectors. Model N-126S, which was our standard model, is no longer in production. It is being replaced by the model N-333.
Most microfluidic applications involve only relative moderate pressures. However, some applications do require working with high-pressures. Occasionally we are asked “what is the maximum pressure that can be applied to our fused silica glass microfluidic chips?”
Wikipedia will tell you that springs are usually made out of spring steel. While that is usually correct, that does not necessarily have to be the case. For some applications you may want to consider a spring made out of glass.
We are happy to provide you with some initial feedback based on a simple hand-sketch of your custom chip; before fabrication starts, though, we ask that you provide us with a quality error-free engineering drawing.
Many customers order chips (or flow cells) with factory-installed Luer connectors. These chips are shipped with a protective luer cap, which is screwed on top of each luer base. The cap prevents contaminants from entering into the microfluidic channels. We strongly recommend that you keep the caps on until you are ready to use the chip.
When you design microfluidic chips, remember that you must allow sufficient space for the connectors to operate properly. You must leave ample space between the connectors, and between the connectors and the edges of the chip. If you are going to use your chips under a microscope objective, you also need to take into consideration the height of the connectors and that of any associated tubing.
