How to unclog a 34G detachable needle that goes on the end of 5 microliter Hamilton syringe?

02 August 2023 0 2K Report

The cause of blockage is deposition of either dried blood or dye particles from microinjection. Unfortunately, immersing the needles in 100% ethanol and flushing them through ethanol, using the hamilton syringe did not unclog it.
