spills, liquid or powder, as soon
as they occur. Refer to
label and accompanying
MSDS for proper
reagent disposal.

4

Use care when dispensing or
handling all reagents due to safety
reasons. Some
chemicals also may cause
permanent stains if spilled.

ANALYTICAL TECHNIQUE

1. Clean glassware is a must for accurate results. Thoroughly rinse
test tubes before and after each test. Caps and stoppers should
also be cleaned after each use.

2. Use test tube caps or stoppers, not your fi ngers, to cover test
tubes and fl asks during shaking or mixing.

3. When adding sample to calibrated test tube, be sure vial is fi lled
to the appropriate mark. The bottom of the liquid (meniscus)
should be level with the desired mark. (Figure 1)

4. When dispensing reagents from bottles fi lled with dropper plug
and cap, be sure to hold bottle vertically and gently squeeze to
dispense the appropriate number of uniform drops. (Figure 2)

5. For those reagents to be added with the screwcap pipet assemblies
enclosed, remove polyseal cap on bottle and replace with the
screwcap pipet.
NOTE: Place the polyseal caps back on the reagent bottles for
longer periods of storage. Be sure that both pipet assemblies
and polyseal caps are thoroughly cleaned before placing on
bottles to avoid contamination.

6. When dispensing reagents from pipets, hold pipet vertically
to assure uniform drop size. This is extremely important when
performing drop count titrations. (Figure 3)

7. To fi ll pipets, squeeze rubber bulb and immerse into reagent.
Release bulb to fi ll. (Figure 4)

8. To accurately dispense powdered reagents with spoon, tap
spoon on edge of reagent container to remove excess reagent.
(Figure 5)

9. When performing tests that include Octa-Slide 2 Comparators,
the comparator should be positioned between the operator and
non-direct sunlight. This allows the light to enter through the
light-diffusing screen at the back of the comparator for optimum
color comparison.

Model S and DuoSoft Softeners

INTRODUCTION

The Model S and the DuoSoft Water Softeners are designed to produce high quality softened

water. As water passes through the Model S chamber, the resin column causes scale-forming
calcium and magnesium ions to be exchanged for non-scale-forming sodium ions. When the
resin is exhausted it must be replaced or regenerated. Inexpensive resin refi ll packages are available,
or the original resin can be regenerated by chemical treatment.

In the DuoSoft, water passes through both chambers and will be treated by both types of media.
The two chambers of the DuoSoft may be easily fi lled with the media of choice for specifi c
problem water.

NOTE: These softeners DO NOT yield water suitable for drinking .

Total Hardness

Total Hardness of a water supply generally represents the total concentration of Calcium and Magnesium ions
expressed as Calcium Carbonate (CaCO3). Other ions may contribute, however, they are usually present in
insignifi cant quantities. Hard waters may form scale on plumbing fi xtures, consume excessive quantities of
soap, and leave deposits of fi lm on glassware, fabrics, etc. Excessive hardness may be removed by various
treatment methods.

Precipitation Demonstration

Again, Calcium and Magnesium ions are the major contributors to water hardness. The chemical reagents in this
demonstration pull the Calcium and Magnesium ions out of solution to form a cloudy precipitate in hard water.
The water that has been run through the ion exchange column has had these ions removed, therefore, the sample
should remain clear.

NOTE: This portion of the AT-38/40 Water Quality Demo Kit is ONLY a visual demonstration illustrating the
removal of Calcium and Magnesium ions from tap water after treatment by the ion exchange process. The
results should not be interpreted beyond the intent of the demonstration.

pH Test

Simply, the term pH can be considered to be an “index” of the amount of hydrogen ions present in a substance.
This “index” can be used to quickly identify the acid, neutral, or alkaline (basic) nature of water. On the scale
of 0.0 to 14.0, 7.0 is considered to be neutral, acidic water is less than 7.0, and basic or alkaline water is greater
than 7.0. Water that is acidic in nature may cause corrosion of plumbing and equipment while alkaline water
may contribute to scale buildup. Neutralization by various methods is used to correct pH for proper operation of
equipment.

pH measurement may be made electronically with a pH meter or as below with a colorimetric method. The pH
indicator used is a mixture of dyes that produces a specifi c color at various pH levels.

Iron Test

Most natural waters contain iron, varying from trace to very large amounts in various forms. In the dissolved
state (ferrous), iron water is often colorless. Upon exposure to air, or an oxidized state, ferrous iron will undergo
a chemical reaction to the suspended (ferric) state causing discoloration, staining, and possibly an objection­able taste. Several methods are available for iron removal, the selection of which is dependent upon the state in
which it exists.
