Anyone have any preferences on injectors for viral injections into the spinal cord and brain? I used the popular WPI UMP4 micropump this summer. It worked, but it requires one to fill a Hamilton syringe and glass pipette with mineral oil all the way through in order to maintain pressure throughout the whole setup.
I’ve seen some papers using a pressure injection system, namely the Femtojet (Eppendorf). This looks attractive because it doesn’t require the filling of oil or other liquid. But I don’t see it used as much. Anyone have any experience?
