1-ml
syringes are very useful tools for volumetric and gravimetric measurements
in microscale chemistry experimentation.
Removing
the needle makes a syringe safer, easier to handle suitable as a measuring
cylinder.
Left
and photo 2: The needle is extracted leaving a nozzle with the very
thin channel of the needle.
This
channel can be easily closed by welding the thermoplastic material.
Photo
3: The needle can also be removed together with the nozzle.
Right:
A bigger hole might be useful to insert an electrode.
