In stock

Pack of 3 focused flow droplet generator chips for use in combination with our sideconnect interfacing. The chips are available with both a coated (hydrophobic) and uncoated (hydrophilic) channel surface.

Indicated reference droplet sizes are based on a reference experiment with Silicone oil 5cSt and DI water combined with 2% v/v Tween 20 or Tween 80.

Pack of 3 single nozzle side connect droplet generators with a nozzle etched on both sides, giving the following advantages:

  • Optimized nozzle geometry
  • Symmetric channels and nozzles for uniform droplet formation 
  • Droplet production stable over a broader size and frequency range
  • Smaller droplet sizes available

This microfluidic droplet generator is an excellent tool 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, droplet size and frequency can be altered. Oil-in-Water (O/W) droplets can be generated directly using the glass chips. Also, these droplet generators are suitable for coating in order to form Water-in-Oil droplets (W/O).

Further specifics:

  • Droplet size can roughly be tuned from the size of the nozzle to be doubled
  • Suitable for foam, digital PCR, single cell analysis, emulsions etc.
  • Made from high quality glass, borosilicate, suitable for most biological and chemical applications

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.
