Questions

  1. What could be recommended O-ring to use (with diameter) with this ace RBF? I need an O-ring resistive towards polar and non-polar solvents and should be inert towards chemicals reactions?

    1 answer

    1. This is a product of Ace Glass. The plug and O-ring are included. The O-ring for the 250ml flask is product Z504858, which is composed of FETFE and has an I.D. 9.2 mm, and a wall size of 2.6 mm. The general compatibility is listed as 'good', however, it would be recommended to review each component. See the link below to review the Ace Glass O-ring compatibility guide.
