Pack of 3 powderblasted H-reactor Chips, (2 inlets, 2 outlets).
The channels in these chips are made with a process called powder blasting. Powder blasting works by shooting a powder to the glass and results in an open channel with a rough surface. in order to make a closed channel, a smooth and flat sheet of glass is bonded to it.
The channel's bottom and sides are powderblasted, and the top of the channel is made by sealing a smooth layer of glass to it. This way, the channels have an undisturbed view from the top and an opaque view from the bottom. Also, even from the top, you will see the roughness of the channel's bottom and sidewalls.

Have a look at our clogging prevention guide
Is your setup clogged with dirt or fully blocked?
Chips can get clogged, for example when they’ve been used before and have not been cleaned the right way. If your chip is clogged with dirt, check our document on the prevention of clogging and/or read the answer to question number one on this page (regarding the cleaning of chips). Clogged chips often do let some flow through the chip, which makes it easier to identify the issue as clogging. If there is no flow at all it’s more likely that the flow path is not connected correctly.
Pinpoint the issue
We recommend walking through the full track of the fluid flows: check if your syringe or pump is not blocked, if your tubing is actually hollow and if your filters let fluids pass through. Then check if your chip has inlet and outlet holes and if these are positioned so that the fluids can go through the chip. The easiest way to do this is to disassemble the setup and check if fluids come out of the pump, then connect the tubing and check if fluids can come through. Keep on adding parts and checking if the fluids go through. This way you can pinpoint the problem.
If the problem remains
If the problem cannot be solved after following the above-mentioned steps, then take some pictures or make a short movie of your setup and send this, together with the description or name of your chip, to Micronit. We will gladly assist you in identifying the issue.
