I am using a Sutter electrode holder for my patch clamp experiments, but I'm having trouble keeping positive pressure inside my electrode due to a leak out of the back of the holder.

I have added small plastic tubing to the inside of the holder around my silver wire, but I am still experiencing leaks.

Any tips/suggestions on preventing these pressure leaks will be appreciated. Here is a video of me adding 3cc of pressure from a syringe: https://streamable.com/veb0cm

(Ignore the bubbles coming out of my electrode, I had performed this multiple times with this same pipette. The electrode is filled with di-water for testing purposes).

Thank you!
