Pour-Thru Cell
A.3 Use of the Pour-Thru Cell
The Pour-Thru Cell is intended primarily for those methods that
specifically call for its use. These use liquid reagents and are
typically denoted as ULR or Rapid Liquid methods. These methods
obtain maximum benefit from the Pour-Thru Cell by avoiding
turbidity from un-dissolved reagents and provide the precision and
sensitivity required to determine very low concentrations. These
methods require no modification when the Pour-Thru Cell is used.
It is possible to use the Pour-Thru Cell for other methods, with a few
minor modifications. The cell requires a minimum volume of 25 mL
