  • Vigreux Distilling Columns

    United Scientific Supplies

    A Vigreux column is a type of air condenser where the simple tube has been modified to include an abundance of downward-pointing indentations. This dramatically increases the surface area per unit length of the condenser. Includes a 24/40 connector.

  • With standard taper 24/40 joints. Length in centimeters refers to the effective length of the column as measured from the lowest to the highest indent of the column.

  • Length in millimeters refers to the effective length of the column as measured from the lowest to the highest indent of the column. Available in a microscale version, top center joint is 14/10 externally threaded for making an O-Ring-Cap-Seal type conn

  • Vigreux style column with indentations that run the entire length of the column for improved vapor-liquid contact. Column length refers to the effective length, measured from the lowest to highest indent in the column. Column has a top outer and lower inner standard taper joint.
