General Information
The Pour-Thru Cell Kit is an optional accessory for the DR 5000 Spectrophotometer. The
Pour-Thru cell improves measurement accuracy, as zeroing, measurements and
measurement comparisons are carried out 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 Pour-Thru is designed to allow the
samples to be introduced into the cell without having to handle the cell in any way.
There are three types of Pour-Thru cells; a 1-inch cell, 1-cm cell and a 5-cm cell. Only the
quartz cells (1 cm and 5 cm) can be used over the entire wavelength range. The 1-inch
Pour-Thru cell can be used in the visible spectrum (340 to 900 nm).
Specifications
Specifications are subject to change without notice.

Assembly
The 1-inch Pour-Thru cell requires the use of a Pour-Thru cell adapter (Figure 1, item 3).
The 1-cm and 5-cm cells use the multi-cell holder supplied with the DR 5000.
Prepare the tubing and Pour-Thru housing
1. Cut the 182 cm (6 ft) length of clear tubing into two equal lengths of tubing,
approximately 91 cm (3 ft) in length.
2. Feed both ends of the clear tubing through the two holes on the side of the housing,
leaving approximately 20 cm (8 inch) inside the housing (Figure 3).
3. Resting the housing on its left side, remove the rubber fitting if installed. Route the
external tubing through the channels molded into the exterior right side of the housing.
Replace the rubber fitting (Figure 3).
Important Note: Do not kink or bend the tubing sharply.

1-inch cell assembly
1. Remove the multi-cell holder from the DR 5000 and replace it with the Pour-Thru cell
adapter (Figure 1, Item 3). Do not screw down the Pour-Thru cell adapter.
2. Place the Pour-Thru module on top of the Pour-Thru cell adapter in the DR 5000.
Make sure the locking screw holes are aligned. Secure the assembly with the two
locking screws.
3. Clean the Pour-Thru cell with a lint-free cloth. Insert the Pour-thru cell with the barb
fittings pointing left.
4. Route the tubing as shown in Figure 4 on page 5, trimming tube length as needed to
achieve smooth curves with no kinks or sharp bends.
5. Assemble the stand and connect the tubing, noting flow direction arrows molded into
the housing where the tubes emerge. The inflow tube is connected to the glass funnel;
the outflow tube is connected to the overflow tube assembly (Figure 5 on page 5).
6. Connect the drain tube (black rubber tube) to the bottom fitting of the overflow tube
assembly. Connect the other end of the drain tube to an appropriate waste vessel.
The tubes can be shortened if necessary.

1-cm and 5-cm cell assembly
1. Arrange the multi-cell adapter so the appropriate cell holder for the Pour-Thru cell
points towards the front of the instrument. Make sure the imprint of the cell type is
visible. Do not screw down the multi-cell holder.
2. Place the Pour-Thru cell housing on top of the multi-cell holder in the DR 5000. Make
sure the locking screw holes are aligned. Secure the assembly with the two locking
screws.
3. Clean the Pour-Thru cell with a lint-free cloth. Insert the Pour-Thru cell in the cell
holder so that the cell windows coincide with those of the cell holder.
4. Route the tubing as shown in Figure 6. Trim the tube length as needed to achieve
smooth curves with no kinks or sharp bends.
5. Assemble the stand and connect the tubing, noting flow direction arrows molded into
the housing where the tubes emerge. The inflow tube is connected to the glass funnel;
the outflow tube is connected to the overflow tube assembly.
6. Connect the drain tube (black rubber tube) to the bottom fitting of the overflow tube
assembly. Connect the other end of the drain tube to an appropriate waste vessel.
The tubes can be shortened if necessary.

Cleaning the Pour-Thru cells
Important Note: Do not use solvents (e.g. acetone) to clean the Pour-Thru cell. A dilute
acid solution can be used for cleaning. Rinse thoroughly with deionized water.
If windows are cloudy or soiled or bubbles form, add 50 mL of a detergent solution to the
cell and wait for a few minutes to allow it to take effect. Then purge the cell thoroughly with
distilled water. If necessary, the 1-inch Pour-Thru cell can be taken apart to be cleaned.
Wipe the windows of the cell with a soft cloth only—paper towels and other paper products
may scratch the glass.
Troubleshooting
Carefully inspect clear tubing for kinks or sharp bends which may restrict the flow of liquid
through the Pour-Thru cell.
Use of the Pour-Thru cell
Since there is a difference in the light path between the 1-inch square cells and the 1-inch
Pour-Thru cell it is necessary to adjust the calibration slightly when using the 1-inch
Pour-Thru cell. This is done by applying a dilution factor of 1.1 or performing a standard
adjustment. The appropriately revised method can be stored as a user program. If the use
of a Pour-Thru cell is prescribed in a Hach method, no adjustment is needed.
Be sure to use the Pour-Thru cell that corresponds with the cell path length called for in
the method. The 1-cm and 5-cm Pour-Thru cells should only be used with Hach methods
that call for those specific cells or with user programs.
Be sure to use the appropriate sample volume and reagents required for each particular
cell. A 1-inch Pour-Thru cell can be used with a Hach method if the prescribed sample
volume is 25 mL. If the prescribed sample volume is different than 25 mL, adjust the
amount of sample and reagents as necessary to achieve the stated minimum rinsing
volume (refer to Specifications on page 1).
Although the Pour-Thru cell can be used for the Hach methods listed in Table 1, the cell
must be thoroughly purged with distilled water between individual samples.
The Pour-Thru cell can also be used to run Nitrogen, Ammonia, Nessler Method and TKN
chemistries. Clean the cell by pouring a few sodium thiosulfate pentahydrate crystals into
the cell. Rinse out the crystals with deionized water.
Important Note: The Pour-Thru cell cannot be used for the Hach methods listed in
Table 2.
