Tips & Tricks

Glass microfluidic technologies are not considered as simple consumables of laboratory which can be trashed just after use. The main reason is easy to understand. Due to the required facilities and equipment’s, the cost of fabrication of glass chips is one of the highest on the market compare to others classical plastics technologies. In LabInGlass we are aware that our product are valuable items.

Lots of end users often asked us some tricks to reuse and restore their chips. Based on her long experience in Klearia’s group, we will give you some small secrets to take care about your product…

  • How to clean and store your microfluidic chip in glass?

“Depending on your experiment requirement obviously, but we always flush all the channels with Deionized water in order to remove maximum of dusts, polymers residues, precipitates. Tap water is not recommended because we don’t control its “hardness” and the possibility of limestone residual coating.

Then flush it with Isopropanol and dry it with filtered air gun.

For a long term storage, I advise to fill the channels with Nitric acid at 0.1M but don’t forget to hermetically sealed the channel!!”
