    General Instrument Operation Use the optional Pour-Thru Cell (Cat. No. 59404-00) with the Multi-pathlength Cell Adapter (Cat. No. 59466-00) to save time when analyzing the same parameter in many samples. Because the same optical characteristics exist for both zeroing and measuring, or when comparing measurements of different samples, any error that would have resulted from optical differences between individual sample cells is eliminated.

  • Page 29: Installing The Pour-Thru Cell

    Pour-Thru Cell can be used where procedures allow it. 2.11 Using the Pour-Thru Cell Most of the DR/2400 Hach Programs specify the use of 25-mm round cells. The Pour-thru Cell and its 1-in./25-mm pathlength can be used as a replacement in most of these DR/2400 Hach Programs.
