Pack of three T-shaped droplet generator chips.

Pack of 3 T-shaped droplet generator chips, for generating higly reproducible microsized droplets.

Microfluidic droplet generators are excellent tools for generating highly reproducible microsized droplets with much higher precision and repeatability compared to conventional methods.

By tuning the relative viscosities, surface tension, and velocities between the dispersed and the continuous phase, droplets of almost any size can be created.

Oil-in-Water (O/W) droplets can be generated directly using the glass chips. For Water-in-Oil droplets (W/O), choose the coated chips.

Customer Questions
How do I clean my chips?

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...

I need a pumping system for my setup. Which one do you recommend?

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/

 

Which flowrates should I use?

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.

I only see streaks of fluids but no droplets. How do I get the droplets?

Decrease your flowrate. Check our flowrate instructions for a more acurate explanation.

Which surfactants should I use?

Use our surfactant guide for advice on surfactants.

How do I prevent clogging of my chips?

Have a look at our clogging prevention guide.

Should I use coated or uncoated droplet generators?

Have a look at our article about surface wetting properties.
