Details

Application
These nozzles create free liquid sheets that are excellent targets for surface studies or bulk studies with soft X-rays. The sheets are flat and smooth, making them ideal targets for optical laser pumps or probes. The thickness of the sheet is on a microscale and varies along the sheet with distance from the nozzle. It is largely independent of flow rates, providing stable targets despite pump fluctuations.

Nozzle type
Micro 2N - is a narrow version of Micro 2 which can be used when a smaller sheet width is needed. The more narrow aspect ratio is also useful for running high concentration samples in vacuum to reduce spray from sheet rims. Sheets are in range 2 µm to 0.6 µm in thickness.

Available products

There are currently three nozzle types available for different sheet thickness needs.

SKU	Name	Q (Typical flow rate)	Sheet Length at Q	Sheet Width at Q
11003383	Micro 2N	3.0 ml/min	2.2 mm	0.32 mm

Alternatives

Interfacing
Sheet and converging nozzles both use the same interfacing concept, which is not compatible with other products in the store. Micronit can connect you with a third party that can supply a compatible interfacing tool.

Product Questions (10)

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.

How can I interface with the sheet/converging nozzles?

You will need a interfacing tool from a third party (Neptune), see details for contact data.
