6.80? It's getting a little confusing now. There never was a FW 6.80 for the G1321B, but maybe you had that on your pump. You did not talk about the configuration you have.
If entire stack gets updated to latest FW and you still see an issue, it is…
Hi Pillai,
Thank you for this information. I recommend trying a different cellular adhesive to see if this improves the detaching. Additionally, you may want to increase your seeding density as 10K/well was used in this paper (though these cells were…
