The Pour-Thru module is an optional accessory for the instrument. The
module contains a sample cell that remains in the instrument while
samples are poured through the cell by means of a funnel and tubing.
Working with the module improves measurement accuracy, as zeroing,
measurements and measurement comparisons are completed under the
same optical conditions. As the samples all flow through the same cell,
errors attributable to the different optical characteristics of individual cells
are excluded. The module is designed to allow the sample to be
introduced into the cell without having to handle the cell in any way.
The Pour-Thru cell can be used over the entire wavelength spectrum of
the and can be oriented to provide two pathlengths:
•
1 inch cell
•
1 cm cell
These two cell types can be used over the whole wavelength spectrum.
Pour-Thru Cell Assembly
The Pour-Thru Cell Assembly must be assembled and installed before
use.
Figure 1
illustrates the assembled unit.
Note: Tubing supplied with the kit may be cut to fit as needed. However,
care should be taken to set up the tubing first, to make sure that pieces
are not cut too short.
Note: If any of these items are missing or damaged, contact the
manufacturer or a sales representative immediatly.

Chemical Hazard. Do not use the Pour-Thru Cell in tests that call for the use of
organic solvents such as alcohols, toluene, chloroform, trichloroethane or cyclo-
hexanone. These solvents may not be compatible with the plastic components of
the Pour-Thru Cell creating the potential for equipment damage and chemical
exposure for the analyst.
