Pack of 3 focused flow droplet generator chips with a nozzle size of 10µm. This limited edition features a thin bottom with a thickness of 175µm. For use in combination with our topconnect interfacing chipholder.

Pack of 3 Microfluidic Droplet Generator Chips – 10 µm Nozzle, 175 µm Thin Bottom Layer

Designed with precision and ease-of-use in mind, these microfluidic chips are ideal for researchers looking to produce highly consistent microscale droplets. Each chip features a 10 µm nozzle and a thin 175 µm bottom layer—similar in thickness to a #1.5 coverslip—making them perfect for high-resolution imaging.

Key Benefits:

  • Generate droplets between 10–20 µm in diameter *)
  • Only 175 µm to the imaging plane—ideal for high-resolution microscopy
  • Symmetric nozzle and channel design ensures uniform droplet formation
  • Stable operation across a wide range of droplet sizes and frequencies
  • Crystal-clear, smooth channels for reliable visualization and flow

Whether you're working on single-cell analysis, digital PCR, emulsions, or foam research, these chips give you fine control over droplet formation. By tuning viscosity, surface tension, and flow rates, you can easily adjust droplet size and production rate.

Additional Features:

  • Compatible with Oil-in-Water (O/W) droplet generation
  • Can be surface-coated to support Water-in-Oil (W/O) systems
  • Made from high-quality borosilicate glass—chemical-resistant and durable

Perfect for lab setups where reproducibility, precision, and optical clarity matter.

Note: This is a limited edition release of our thin-bottom droplet generator, based on a proven existing design. We’re using this early series to gather feedback from researchers like you—especially regarding additional observation features you'd like to see in future versions.

*) Obtained 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.

Customer Questions
How do I clean my uncoated chips?
1) Flush an alkaline solution through the channels, like 1 M sodium hydroxide in water. 2) A water bath with ultrasonic agitation can be used to remove particulated matters, keep energy levels initially low to prevent potential damages. 3) Glass microchips can be heated (e.g. 400°C) causing any organic material on the glass surface to degrade. Try to use lower temperatures first because burning the content could make it stick. 4) Concentrated sulfuric acid works well to dissolve organic material, such as fibres, that are difficult to remove with alkaline solutions.
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?
Advice on how to find the right flow rates and to to change the droplet size can be found under "Read More".
I only see streaks of fluids but no droplets. How do I get the droplets?
When you only see streaks of fluids its important to decrease your flowrate. Instructions to find the right flow rate can be found under "Read More".
Which surfactants should I use?
Tween 20, Tween 80 and Emulseo FluoSurf™-O surfactant are used in combination with our chips. See "Read More" for details.
How do I prevent clogging of my chips?
Clogging can only be avoided by working as cleanly as possible. Typical sources of particles include: - Dust from the air or open surfaces - Larger particles or other contamination in the fluids - Dried or solidified residues when re-using chips from previous runs - Components within the fluidic setup (e.g., tubing, connectors, reservoirs) - Residual particles remaining after cleaning See “Read More” for detailed advice on minimizing these risks.
Should I use coated or uncoated droplet generators?
For water-in-oil droplets, use droplet generators with a hydrophobic coating.For oil-in-water droplets, no additional coating is needed. Below more details on surface wetting properties are explained.Surface wetting propertiesThe contact angle between the fluid and the droplet generator surface is key for defining the stability of the wetting of the continuous phase. If the wetting is more preferential for the dispersed phase, pinning of the droplets to the channel can occur. The standard uncoated droplet generators of Micronit are glass based, thus hydrophilic and are suitable for making organic droplets in an aqueous phase (oil-in-water droplets). It is possible for Micronit to provide a coating which renders the surface of the droplet generators hydrophobic, thus suitable for making aqueous droplets in an organic phase (water-in-oil droplets). This coating is based on a fluorinated polymer and ensures the coated surface has a contact angle of more than 90° with water.
I have a Elveflow OB1 pressure based pump what connectors do I need?
You need a combination of items supplied by Elveflow and Micronit. Please take a look at the full answer for more details.
I have a Fluigent pressure based pump, what connectors do I need?
See "Read More" for advice.
What's important in selection of a suitable microscope objective?
The objective working distance is a critical parameter for selection of an objective. See "Read More" for recommendations.
Does those droplet generators work well with Emulseo surfactants and Oils?
Micronit hydrophobic coated Glass Droplet generators are tested with the combination of Emulseo FluoSurf-O™ surfactant and Emulseo FluoOil™ 7500 oil and good results are obtained.
Can I apply a hydrophobic coating myself using Emulseo Fluo-ST3™ surface treatment?
The combination of Micronit glass droplet generators and Emulseo Fluo-ST3™ surface treatment is tested and works well.
