Sentinel Chamber Testing System Product List
Sentinel Chamber is a specially designed container for monitoring
the effect of treatments or ecological changes on important indicator
Wastewater Treatment Monitoring
The water and wastewater treatment Sentinel Chamber is designed
to contain organisms that should be monitored to prevent health
concerns. The chambers are placed in water or wastewater before
treatment and recovered after treatment. The organisms are then
extracted from the chamber and their viability is tested. This simple
system enables you to monitor the efficacy of treatments and provides
an easy method for determining if the treatment is reducing pathogen
viability. Water or biosolids from your plant can be placed in the
chambers along with a predetermined number of indicator organisms.
Indicator organisms available:
___ Oocysts of Cryptosporidium
___ Cysts of Giardia lamblia
___ Eggs of Ascaris suum
Food Processing Safety
The Sentinel Chamber for food processing plants contains:
___ E. coli or
X 1" Polycarbonate "Californian" Chamber,
has US#400 (38 micron) stainless steel mesh on each end.
Brewster" is our 2" wide by 1" in diameter
polycarbonate chamber, with US#400 (38 micron) stainless steel
mesh on each end, and a 3/4" opening on the side for
loading semi-solid material or liquids.
made cages for housing the Sentinel Chamber are
For large-scale field work, the cage containing
the Sentinel Chamber with eggs/oocysts, can be attached
to a steel cable for easy removal from the ground (lagoon,
compost windrow, etc.) at sampling times
Easy to Use
Excelsior Sentinel, Inc. has developed a series of inexpensive containers
that makes the recovery of Sentinel Chambers from large test
systems easy. The Sentinel Chambers are resistant to most
environmental extremes and have remained in soils and manure piles
for up to six months without any observed detrimental effects on
Excelsior Sentinel, Inc. will gladly provide methods for the recovery
of oocysts from the Sentinel Chamber. Excelsior Sentinel,
Inc. does not perform viabiltiy assays on the organisms after field
testing, but can refer clients to laboratories that do.
For process development, the Sentinel Chamber provides
an efficient method to test specfic disinfection procedures, allowing
more tests and results in shorter times
The Sentinel Chamber can be filled with oocysts in
water or wastewater from the specific facility being tested so that
the environmental conditions unique to that facility are replicated
inside the Sentinel Chamber.
For testing laboratories, the Sentinel Chamber provides
significant savings due to the elimination of tedious and expensive
processing of large volumes in order to recover enough oocysts for
The Sentinel Chamber provides a source of guaranteed
viable oocysts on short notice (within 2 days of receipt of wastewater
sample). It eliminates the need for collecting and preparing large
volumes for shipment to the testing laboratory and allows for pinpoint
testing of specific parts of the overall process.
Sentinel Chamber testing systems come with certificates of viability
for the indicator organism and are delivered via overnight express.
