Section 3 Installation of the Sampler
Note
Do not pack the bottle rack with ice if you need to ship it to a
laboratory. The styrofoam carrier cannot be adequately sealed,
and the cardboard shipping carton is not waterproof. Use only
gel-packs for cooling. Additional bottle racks, styrofoam carriers,
and shipping cartons are available from Teledyne Isco.
3.4.3 Cleaning the Bottles After the bottle rack has been returned from the testing laboratory,
you will need to clean the bottles and reload the rack.
Cleaning the bottles is an easy procedure, but you must disassemble
them first.
1. Remove the bottles from the bottle rack.
2. Remove the stainless steel valve stem from each bottle.
(Hold the bottle in one hand and pull the stem firmly
toward you with the other hand. Turn the handle back and
forth while you are pulling it toward you.
3. Unscrew the cap from the bottle to free the valve body.
4. Push the valve body out of the cap and remove the O-ring.
Note
The construction of the cap keeps the O-ring from ever contacting
the sample. In this application the O-ring serves as a
spring to help seal. It is not necessary to sterilize the O-ring.
Also, some solvents and detergents could attack the O-ring.
5. Clean all parts in an autoclave or with appropriate detergents.
Note
If you use detergent or solvent to clean the bottles, make sure
the detergent or solvent is non-residual. Non-residual means
that no trace of the detergent will remain on the glass after
rinsing and air-drying. Cleaning agents that leave any residues
could cause misleading results when you use the bottles to
take future samples.
6. After cleaning, allow the bottles, caps, valve bodies, and
stems to air dry in a clean, dry environment.
7. Reassemble the bottles, lids, and valves while you are
wearing rubber gloves, to avoid contaminating them.
8. Put the O-ring on the top of the valve body.
9. Put the cap over the valve body.
Note
The O-ring must be between the cap and the valve body. Do
not place the O-ring between the valve body and the bottle.
10. Screw the cap down onto the bottle.
