Safety Information

Read the instruction manual thoroughly to familiarize yourself with the test procedures before you begin. Make note of any precautions in the instructions.

Read the labels on all LaMotte reagent containers prior to use. Some containers include precautionary notices and ﬁ rst aid information. Certain reagents are considered hazardous substances and are designated with a * in the instruction manual. Material Safety Data Sheets (MSDS) are available at www.lamote.com. Read the MSDS before using these reagents. Additional emergency information for all LaMotte reagents is available 24 hours a day from the Poison Control Center listed in the front of the phone book. Be prepared to supply the name and four-digit LaMotte code number found on the container label or at the top of the MSDS. LaMotte reagents are registered with a computerized poison control information system available to all local poison control centers.

Keep equipment and reagent chemicals out of the reach of young children.

Protect Yourself and Equipment: Use Proper Analytical Techniques

Testing Hints

1. 2. 3.

Tightly close all reagent containers immediately after use. Be sure not to interchange caps and pipets from containers.

Avoid prolonged exposure of equipment and reagents to direct sunlight.

Protect reagents and components from extreme heat and cold.

Wipe up any reagent chemical

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

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 .

Instructions for Use

PROCEDURE A — Use of the Softeners

1. 2.

Allow water to run from faucet brieﬂ y to visually gauge pressure.

3. 4.

SLOWLY turn on faucet and adjust the ﬂ ow of water into softener until the stream of water is about 1/8” in diameter. Maintain a gentle ﬂ ow to prevent excessive pressure in the adapter.

5. 6.

Unclamp outlet hose at bottom of softener.

Attach adapter on inlet hose to faucet. Fully open clamp on inlet hose.

Fill chamber until a 1” layer of water is visible over the media.

Let efﬂ uent run to waste for about 3 minutes to wash out residue from the previous sample.

minutes

Adjust ﬂ ow to maintain the 1” layer of water over the media.

9. 10.

When softener is disconnected from faucet, clamp inlet hose.

After enough softened water has been collected, turn off faucet and clamp outlet hose

If softener will be stored unused for any length of time, keep a 1” layer of water over resin column to prevent drying and cracking.

PROCEDURE B — Replacing the Media in the Softeners

1. 2.

With the aid of a funnel, add the fresh media to the column.

3. 4.

Continue adding media to the column until the resin is about 2” from the top of the column.

2”

ADDITIONREMOVAL

5. 6.

Clean threaded area completely and replace the black plug in the top of column.

Tap water may be added to the media in the funnel to facilitate ﬁ lling of the column.

Allow excess water to drain from outlet hose.

DuoSoft Unit

To add the media in the bottom chamber, turn unit upside down and repeat Addition Steps 1-5. When media has been added to both chambers, proceed with Procedure A. When using carbon media, it is suggested that it be used in the top chamber.

To replace media, remove black plug from the top of dispenser.

3. 4.

By adding more water to the column and shaking, the remaining media can be easily removed.

To remove the media in the bottom chamber, turn unit upside down and repeat Removal Steps 1-3. To add new media, follow Addition Steps 1-5 for both chambers.

Unclamp outlet hose and turn softener upside down.

Allow exhausted media and water to run to waste.
