    If you can use a solvent - just do it. bsp I would try to pour a bit of the initiator into a beaker (not that difficult to weight) and dilute with the solvent. Solution should have much lower viscosity and would be probably easy to transfer into a flask. You may need some tricks to make sure you know the concentration, but it is all a matter of tracing masses of everything involved in the process.Besides, if the initiator is that sticky even mixing it with other reagents can be tricky, so the solvent can make it easier to homogenize the solution and get the polymerization right in all the volume.

    Hi I'#039m trying to perform a polymerization which requires a super sticky initiator (2-hydroxy-2-phenyl piperdine). It'#039s roughly the consistency of honey and I want to transfer a measured quantity into a round bottom flask. Is there a standard way of doing this? I tried putting the flask on a balance and measure it out with a spatula a few times but it'#039s hard to do without getting it on the neck / wasting material stuck to spatula/etc. bsp I'#039m considering dissolving it in solvent first and then adding it to the fla
