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 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 a Fluidic connect kit.
Glass microchips can be heated (e.g. >400° C) causing any organic material adsorbed on the glass surface to degrade. Try to use lower temperatures first because burning the content could make it stick. Make sure you only heat the glass chip and not the plastic parts around it.
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.
Please note that chips that were coated by Micronit have different guidelines for cleaning.
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. Micronit can offer serveral different pumping systems. A droplet platform including pumping system can be found here. You can also send us an email to find out which pump would work for you.
This depends on many things, for example, which fluids you use. Check our flowrate instructions to find out how to start.
Decrease your flowrate. Check our flowrate instructions for a more acurate explanation.
