Single Neck Cow Receiving Flask 

USA MADE Single Neck Cow Receiving Flask with 24/40 female ground joints. Cow receiver volume is 250ml. Includes GL-14 port. 

• When using with a distillation system, it is recommended to have two Single Neck Cow Receiving Flasks. The first one will be used for the first volatile fraction. Once this fraction is completed, the user will swap with a clean Single Neck Cow Receiving Flask so that the second fraction is not contaminated. For the third fraction, only the receiving flask needs to be swapped not the Single Neck Receiving Cow.
