Decant your sofnolime from the larger (20kg) Molecular products sofnolime tubs into the smaller  portable (4.7kg) Molecular tubs easily and quickly. The funnel screws directly onto the smaller tub. 
The larger bore of the funnel aids in the smooth flow of sofnolime. 
Please check the molecular tub thread photograph before ordering as the older tubs have a different thread. We can make funnels for the older tubs, please contact if you would like one for an older tub.
