PLGA Microparticle Production Station
The PLGA microparticle production station is a robust, high performance solution to generate polymer microparticles in a homogenous and fully controlled manner. The performance brought by the RayDrop droplet generator, with the combination of poly(lactic-co-glycolic acid) as an encapsulation polymer and ethyl acetate as a solvent provide a biocompatible solution lowering both hazard risk and precipitation time. Suitable for biological applications, the RayDrop and its station offer a semi-automated solution for one of the most successful drug delivery systems in laboratories and clinics. To solve the current problems of the PLGA microparticles synthesis, droplet based microfluidics appears to be a powerful tool. Droplet control and generation allows highly monodispersed and continuous production as compared to batch emulsion methods.

APPLICATION PACKS
The PLGA microparticle production station is available in 3 different packages depending on ones requirements. Each pack was designed to perform PLGA microparticle generation, and a detailed protocol has been created and designed specifically for this application. Thus, any pack owner can use it smoothly, in a semi-automated way. The station remains fully modular and each parameter can be modified so you have a complete control of your expected results.
STANDARD PACK
The standard pack offers the possibility to generate PLGA microparticles manually by using the potential of the RayDrop device and the fluid control precision and stability with Fluigent instruments.
AUTOMATION PACK
The automation pack offers the possibility to generate PLGA microparticles in a semi-automated way using the 2-SWITCHTM and the MAT Software. By eliminating manual manipulation, the station executes your protocole to provide better results.
FULL PACK
The full pack extends the automation pack with the possibility of observing/recording your results in real-time with a quality microscope and high frequency camera. The setup has been optimized in order to produce superior results.

TECHNOLOGY
The RayDrop is a microfluidic device composed of three main parts fully removable: two inserts on each side and a center section containing a nozzle and an outlet capillary. There are four microfluidic connections, two on the box for the continuous phase, and one on each insert for the dispersed phase entry and the mixed phase exit.
The RayDrop works as a co-flow focusing principle. The nozzle and outlet capillary are aligned in continuous phase chamber, the dispersed phase comes through the nozzle to create the microparticles into the continuous phase and exit by the outlet insert.

Testimonial
“My team has started using the Fluigent microfluidic kit for making polymer based particles. We tried different microfluidic systems in the past but unfortunately they were not suitable for our application. The main issue was chip blockage which rendered the process quite laborious.
The RayDrop microfluidic chip from Fluigent gave us the best results with a better control over the process.
I have to mention the excellent technical support from Fluigent, their team visited my lab 3 times to deliver training and help to optimize the process”

FAQ
As chemicals, can be used ethylacetate, ethanol or IPA. (The nozzle material is not compatible at long-term use with dichloromethane)
The method has been designed for PLGA. Changing polymers may change the physical fluid properties and lead to different results.
Yes, we recommend filtering all solutions before starting your experiment. The presence of dust can block the nozzle.
Open the top plugs of the RayDrop.
Return to the RayDrop filling state.
Refer to the application note protocol.
Leaks can sometimes appear if the fluidic connectors are not tightened enough.
Check that all the connectors are attached firmly.
(Be careful not to over tighten or your tubing may be blocked by pinching)
If the RayDrop has been manipulated (for cleaning or maintenance) the four screws might not be tightened enough.
Use an allen key to tighten.
Follow the procedure detailed in the application note.
Please note the priming and cleaning procedures.
If the usual cleaning procedures from the good practice guide cannot unclog the nozzle, contact customer support for help.
If some ethylacetate without PLGA has flowed into the chamber it can be flushed out easily.
Follow the instructions in the good practice guide.
If some ethylacetate without PLGA is fixed around the nozzle, it can be easily flushed out.
Follow the instructions in the good practice guide.
If some PLGA gets into the chamber, it has to be eliminated quickly.
Refer to the good practice guide for the exact procedure.
It is important to clean the RayDrop after each experiment in order to prevent clogging.
Refer to the good practice guide for the detailed procedure.
Make sure that all tubing is well flushed before connecting the RayDrop.
If air bubbles appear during experiment we advise one to switch to the ethyl acetate solution (if you are in the PLGA configuration) and let it flow for a minute to remove all PLGA from the system.
Then make sure that all connectors are tightened properly.
Refer to the application note procedure to avoid air bubble infiltration.
