Richard, is this still an actual problem you have?

not any longer

I passed it over to a ULT specialist as I needed 300gms but the refrigerant was only available in 8kg bottles and at over 200 Euro's per Kg it became not cost effective. Not sure what happened after that.

It's normally R508 for the newer units and R23 for the older ones.
You mostly can fill it at a standstill temperature of 20C to a certain equilibrium pressure.
It's sometimes on the nameplate
