CODE 3-0026

CA PAC ITY:

60 mL in collecting bottle (0688-DO) for dissolved oxygen test
450 mL in water sampler for additional tests

IN TRO DUC TION

This unique device collects samples
representative of specific depths and
is particularly suited to the collection
of dissolved oxygen samples. Discrete
samples may be taken at specific
depths by using the attached stopper
and an optional calibrated line and
two pound weight (1064-G). Simply
lower to sampling depth. When trip
line is pulled, sample collecting
bottle will begin filling, overflowing
and flushing more than 5 times.
During retrieval, decreasing water
pressure prevents the exchange of air
and water with sample. Excess water
in sample chamber can be used for
additional tests. The interior
chamber also accommodates
LaMotte Model 545 Armored
Thermometer (1066) to accurately
measure the sample temperature.
Gently press the thermometer into
the hole in the base of the sampler,
and read temperature through the
clear sampling bottle body.

PRO CE DURE

The collecting bottle (0688-DO) included with the Water Sampling
Bottle (3-0026), is the same as that provided in LaMotte dissolved oxygen
test kits. The Water Sampling Bottle will also accommodate 60 mL, flared
lip, glass-stoppered BOD bottles (2-2053).

1. Lift wire lid retainer up and away from sampler to release lid. Remove
the plastic lid with inlet tube attached, sliding it up the rope bridle.
Insert a collecting bottle (0688-DO), with the cap removed, into the
inner chamber of the sampler.

2. Replace the plastic lid, inserting the inlet tube in the collecting
bottle. Snap the wire lid retainer into grooves on the lid.

3. Attach a two pound weight to the snap clamp at the bottom of the
rope bridle.

4. Attach a calibrated line to the loop at the top of the rope bridle.

5. Press the plastic stopper securely into the center inlet hole. Lower the

water sampling bottle to the desired depth.

6. Collect water sample by removing the stopper from the inlet hole
with a quick jerk of the calibrated line.

NOTE: As air is displaced by water entering the sampler, bubbles
will be observed rising to the surface (downstream). When the water
sampler is filled, bubbles will no longer appear. Filling takes about 45
seconds to one minute.

7. Use a steady, hand-over-hand motion to retrieve the water sampler.
NOTE: If the thermometer is used with the sampler, read the

temperature through the clear sampler body WITHOUT removing
the thermometer from the sample. Record temperature.

8. Place the sampler on a flat surface.

9. Release wire lid retainer and remove the plastic lid with inlet tube

attached, sliding it up the rope bridle.

10. Remove the collecting bottle (0688-DO) from the inner chamber of
the sampler. If a dissolved oxygen test is to be performed on this
sample, follow the directions in your dissolved oxygen test kit.

11. The remaining water in the sampler can be used to perform additional
tests.
