How to test if all electrodes MEAs are working or if the MEA is good to be used or should be discarded

Post  DiSh on Fri Mar 28, 2014 12:07 am

Dear Manager,

I would like to know how do I check if I can still use a particular MEA or Not

The MEAs in my lab have been at 4c since one year and I wish to know the shelf life of the chips.


I have tried checking the impedance of all my MEAs , which give a reading around 107-140 average

In some MEAs the reading is more even of around, 112 for all the electrodes.

How do I know If I can still use the chips or no?

(I have tried to clean MEAs by Tera E Zyme , Autoclave and plasma cleaning also post which I checked the impedance)


Awaiting Your Quick Reply

Many Thanks

Dish

Dear Dish,
the impedane values sound good to me, so the MEAs should be fine. It's hard to name a certain shelf livetime, as most customers use them straigth away. We guarantee 6 month, but they last much longer. I would use the principle As long as there are signals, they are OK.
