3-Pack Focused flow droplet generators (nozzle size 5 µm)
€395.00

Availability: In stock

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

Share this product on:

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

  • Optimised nozzle geometry
  • Symmetric channels and nozzles for uniform droplet formation 
  • Droplet production stable over a wider 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:

  • Nozzle size 5 µm
  • Droplet size can roughly be tuned from the size of the nozzle to double this size
  • Filter for filtering out impurities
  • Suitable for foam, digital PCR, single cell analysis, emulsions etc.
  • Made from high quality glass, borosilicate, suitable for most biological and chemical applications.

Application examples:

Cell, DNA, bead encapsulation for

  • drug discovery
  • drug studies
  • molecular biological studies
  • immunology studies
  • evolutional studies
  • enzyme catalysis studies.

Food, paints, foams

  • Bubble formation
  • Mineral Oil Emulsion Production
  • Particle production - PLGA, PEGDA, gelatine, alginate, polystyrene, agaros
  • Drug delivery - creams, aerosols

Chemical

Q: How do I clean my chips?

Q: How do I clean my chips?

A:  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 remaining inside the chip after cleaning and rinsing with water pose a problem then ammonia can be used instead. Note that the these solutions are caustic and can cause damage to e.g. the polyimide coating of fused silica capillaries. Also plastic parts should not be exposed to very alkaline solutions.

In order to aid in the removal of particulate matter, a water bath with ultrasonic agitation can be used, preferably while flushing a watery solution through the channels using an Fluidic connect kit.

Glass microchips can be heated (e.g. >400° C) causing any organic material adsorbed on the glass surface to degrade.

Concentrated sulphuric acid works well to dissolve organic material such as fibres which are difficult to remove with alkaline solutions, but because of the extremely corrosive nature of the material a cleaning procedure is not so easily implemented.

 

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

A: There are several high precision pumping systems on the market that work with different pumping principles. Many of our customers use for example the Fluigent pumping systems. Those systems are made to realize pulsation free, smooth and precise fluid delivery.
