* Required Fields

This setup does not include pumps. For droplet generation, we recommend pressure based pumps to ensure an optimal experience. Pressure based pumps use stabilized pressure to push liquid out of a reservoir. Syringe pumps can generate a step wise movement in pressure release. This can result in pulsations, that cause instability in droplet generation. There are some high-end syringe pumps on the market that might overcome this issue, but we have limited experience with such pumps. For use in combination with high-end syringe pumps our Syringe to tube connection kit might be a useful addition. 

Droplet generation chips are available in the following types:

  • Focused Flow 
  • T-shaped
  • Parallel

 

Focused flow droplet generators are available in the following configurations:

SKU Nozzle size Coating Use for Recommended droplet size
(reference liquids)
00935 10µm Non - Hydrophilic Oil-in-water droplets 9µm< droplets <20µm
01341 Hydrophobic Water-in-oil droplets
02137 (Beta product) 20µm Non - Hydrophilic Oil-in-water droplets 15µm< droplets <30µm 
  Hydrophobic Water-in-oil droplets
00877 50µm Non - Hydrophilic Oil-in-water droplets 40µm< droplets <90µm
01366 Hydrophobic Water-in-oil droplets
00580 75µm Non - Hydrophilic Oil-in-water droplets 65µm< droplets <140µm 
00970 Hydrophobic Water-in-oil droplets

T-shaped droplet generators are available in the following configurations:

SKU Coating Use for Channel width Channel height
FC_TSDG.2_PACK Non - Hydrophilic Oil-in-water droplets 100µm 20µm
FC_TSDG.C.2_PACK Hydrophobic Water-in-oil droplets 100µm 20µm

Parallel droplet generators combine multiple focused flow droplet generators in parallel on a single chip with a shared inlet and outlet for increased production rates. They are available in the following configurations:

SKU Nozzle size Number of junctions Coating Use for Recommended droplet size
(reference liquids)
00923 75µm 8 lanes Non - Hydrophilic Oil-in-water droplets 65µm<droplets <140µm
02067 Hydrophobic Water-in-oil droplets

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.

I have a Elveflow OB1 pressure based pump what connectors do I need?

Nuts and ferrules

Elveflow uses 1/4-28 screw in connections on there reservoirs and sensors. To interface you will need Flangeless nuts 1/4-28 for 1/16" tubing, including compatible ferrules. Those nuts and ferrules are included in Elveflows "Kit Fittings Starter Pack Push-in".
This item wil look like this:

In addition you will need our connection kit. Our Connection kit includes nuts or ferrules specificilly designed for our Fluidic Connect Pro, Fluidic Connect 4515 or side connect holders.

Tubing included in "Kit Fittings Starter Pack Push-in"

The 1/16"OD PTFE tubing included in the kit has a very large ID (1/32" ~0.79mm) and is from a relatively soft material, this is not so suitable for bot our Fluidic Connect Pro and Fluidic Connect 4515 holders as there's very limited wall thickness. We recommend alternative tubing, like ETFE with a maximum of 0.5mm ID. This tubing is included in our connection kits.

Use of 1/32" tubing
1/32" tubing can be in combination with our Fluidic Connect Pro holder also be used, but need alternative ferrules. The ElveFlow "Kit Fittings Starter Pack Push-in" doesn't include sleeves for use of 1/32" OD tubing. They are included in our "Syringe to tube connection kit"
Our Sideconnect our Fluidic Connect 4515 holders doens't support 1/32" tubing.

I have a Fluigent pressure based pump, what connectors do I need?

Lineup

We recommend the dafault Fluigent kits (FLOW EZ™ SUPPLY KIT, FLUIWELL KIT or P-CAP KIT)
The P-cab or FLUIWELL KIT already contains 0.5m 1/16" OD FEP tubing with a ID of 500µm, when you use only limited pressures, you can try this tubing first and only order:

For optimal performance we recommend our complete connection kit, the FEP tubing might be a bit soft limiting the pressure rating. 

MFCS

We recommend the dafault Fluigent kits (MFCS™-EZ HIGH/LOW PRESSURE KIT, FLUIWELL KIT or P-CAP KIT ) 

The P-cab or FLUIWELL KIT already contains 0.5m or 1m 1/16" OD FEP tubing with a ID of 500µm, when you use only limited pressures, you can try this tubing first and only order:

For optimal performance we recommend our complete connection kit, the FEP tubing might be a bit soft limiting the pressure rating.
