Parallel droplet generator - topconnect
Pack of 3 parallel droplet generators with 8 nozzles, available with and without hydrophobic coating.
Looking for a way to scale up your experiment? Then replace your single droplet generator with this parallel droplet generator and increase your production rate by eight times! The chip contains eight nozzles which share mutual inlets and an outlet, so only three external connections are required.
This pack contains three parallel droplet generators with nozzles etched on both sides. The chips are similar in functionality to the, but have eight nozzles.
It could be preferential to first build your setup with a single nozzle droplet generator before using the parallel droplet generator with eight nozzles. For example, if your supply of sample material is limited or expensive (eight nozzles use eight times as much sample material) or if you are trying to build understanding of how the droplet size responds to changing parameters (one nozzle is easier to understand than eight nozzles that influence each other).

One simple but very effective way to clean a microchip is to flush an alkaline solution through the channels. A solution of 1 M sodium hydroxide in water works well, but a lower concentration might also be sufficient. If traces of the cleaning solution...
We recommend using a high precision pumping system. Regular syringe pumps often don't work very well for droplet generators. There are several high precision pumping systems on the market that work with different pumping principles.
To name one, we'd like to mention that we have had positive experiences with the equipment Fluigent offers: https://www.fluigent.com/
This depends on many things. For example on the type of fluid that you are using. Check our flowrate instructions to find out how to start.
Decrease your flowrate. Check our flowrate instructions for a more acurate explanation.
