If you want to minimize
exposure to moisture and use the less costly 4 liter bottle of
Acetonitrile to dissolve your amidites, we offer an amidite
Diluent station that does just that.
Our Amidite Diluent Station usually comes with a 38 mm bottle
cap which fits directly onto the standard 4 liter bottle of
Acetonitrile that is sold in the USA and in some other
countries.
We also offer an
adapter that allows you to use a bottle of Acetonitrile with
a 45 mm cap.
If you are concerned about the larger bottle of Acetonitrile
becoming contaminated with water because it takes a long time to
use, we offer
Molecular Traps which are designed to remove moisture form
solvents and to maintain a very low moisture level in solvents
such as Acetonitrile.
