5.5 Special Systems
5.5.1 5/8 in. Systems
In applications with large particles or materials in the source liquid, a 5/8 in. ID
system will help prevent clogging. The added diameter adds 66% more
volume to the entire system.
For a sampler to increase to a 5/8 in. ID, the following parts and components
are changed to allow for more volume: intake tube, volume control tube, all
fittings, metering chamber, metering chamber lid, discharge tube, sample
container cover, and sinker or strainer. The 5/8 in. system is only offered for
our composite samplers.
5.5.2 Sanitary Systems – Teflon and Glass
In applications wherein the water sample must be prevented from coming into
contact with any plastics, a sanitary system is recommended. For example,
when testing for acid/base/neutral extractable organics and pesticides, the
sanitary system will keep the final sample clean from any contaminants.
The sanitary system includes changing all “wetted” components of the
sampling system (that is, everything that comes in contact with the final
