What is a microbial sampler?
A microbial sampler captures viable (biologically active) particles, such as
bacteria and fungi, by drawing an air sample over a petri dish containing an
agar. The sample is incubated, allowing any viable particles to grow and form
colonies in the agar. After incubation, any colonies can be counted to
determine the concentration of CFUs (Colony Forming units) present in the air
sample.
A particle counter gives an instant indication of a potential problem, allowing
production to be halted before expensive ingredients are wasted, but a
particle counter cannot determine whether the particles are viable or not. The
microbial sampler reveals the presence of viable particles, but only after an
incubation period. Where viable particles are a concern, a comprehensive
monitoring system requires both non-viable particle counters and microbial
sampling. The release of product depends on the results of the incubation of
the agar.
Choose Climet for dependability
Climet microbial samplers have sturdy, stainless steel enclosures, preferred for
resistance to cleaning solutions. The overlays seal the display and LED
openings, protecting the display and internal electronics from cleaning
solutions.
ISO 14698 specifies a cubic meter sample “in a reasonable time” that avoids
drying of the agar. Climet microbial samplers provide 100 LPM flow,
completing a cubic meter sample in 10 minutes. The samplers use the same,
proven vacuum source used in Climet particle counters since 1993. This
rugged vacuum source maintains accurate flow, even after the instrument
has been dropped.
The DC powered blower provides a regulated vacuum source. The blower
allows the portable models to operate on battery power 7.5 to 9 hours on a
full charge. The exhaust is filtered, emitting no more than one 0.5 micron
particle per cubic foot.

Choose the CI-90 for traceability
The CI-90 portable microbial sampler comes with a built-in label printer. Print
up to 3 matching labels to identify the ager dish and records, eliminating
recording errors and assuring that the sample is correctly identified.
The CI-90 allows the printout to identify the unit (Unit ID), the location (Site ID),
and the user (User ID). The printout also records the sample volume and the
date and time.
From the menu the following parameters can be set:
The sample volume—5 liters (3 seconds) to 1100 liters (11 minutes),
The time delay to allow the user to leave the area—3 seconds to 99
minutes and 59 seconds,
The number of labels to print,
A flow alarm,
Beep on completion of the sample,
Security options.
The CI-9X Loader software is provided with the CI-90. This program allows the
user to enter site IDs and their default sample volumes into a computer file,
which can be uploaded on to multiple CI-90s and serve as a back-up for
settings.
Choose the CI-95 for smaller size
The CI-95 is like the CI-90, but does not have a printer; this makes it smaller and
lighter than the CI-90, and less expensive.
For some applications, an entire process may need to be monitored from
beginning to end. To accommodate sample processes greater than the
normal ten minute sample period, the microbial sampler allows the user to
segment the sample into short duty cycles spread over as much as three
hours.

Choose the CI-99 for permanent installations
The CI-99 is housed in a stainless steel enclosure with a
flanged inlet and outlet that can be used with stan-
dard stainless steel tubing and clamps to place the
sample head in the desired location. The
enclosure is rated IP-54 to facilitate cleaning.
The front panel has six status LEDs:
Power Illuminates (green) when on
Sample Illuminates (green) during sampling
Alarm Illuminates (red) for flow alarms or if
there is a setup error
Delay Illuminates (amber) during delay
Blower Illuminates (green) when blower is
on
Ethernet Illuminates (amber) when Ethernet
is connected; blinks when
communication is in progress
While the portable microbial samplers allow remote sampling with adapters,
the CI-99 is better suited for permanent installations. The use of flanged,
stainless steel piping with sanitary fittings provides a clean, reliable installation.
The stainless steel piping makes cleaning easier.
The sampling assembly comes in two versions: with a side or bottom port. This
allows greater versatility in placing the sample assembly.
Ethernet allows the CI-99 to be started remotely, and allows settings to be
made through a computer. Permanent installations are typically used to
monitor a process which may last as much as an hour, or more. Like the
portable models, the CI-99 can extend the sampling period by segmenting or
splicing the sample period into a number of sampling segments separated by
idle periods—a duty cycle—that allows the entire process to be covered.
The sampling activity can be controlled via Ethernet, but the sampling can
also be controlled by external contacts (such as through a PLC), and the CI-99
has internal contacts which can be connected to the PLC or other indicators
monitor the status of the sampling.

Accessories expand sampling capabilities
Remote sampling
Accessories allow the microbial samplers to be used in a variety of situations.
Remote sampling adapters allow the sample head to be placed remotely,
away from the portable sampler, when the
sampler will not fit in the area to be sampled.
The sample head is removed from the
instrument and replaced with an adapter
(left) with a hose
port; the
sample head
is installed on
the remote
sample assembly
(shown at right, with a side port and the
sample head installed; the remote head
assembly is also available with a bottom port).
The remote sampling head and the remote
sampling adapter are connected through flexible tubing. Proper flow is
maintained by the flow control circuitry of the CI-90 and CI-95.
The CI-99 is designed specifically for remote sampling in permanent
installations. The CI-99 comes supplied with a choice of sampling assemblies.
The sampling assembly has either a side or bottom port; the port is flanged,
making easy attachment to the flanged stainless steel pipes used with the
CI-99.
Sampling compressed air
Climet offers an adapter for use with a
High Pressure Diffuser. The adapter
contains the sample head, and is
cone-shaped to allow the
sample to spread out to the
dimensions of the head. The
High Pressure Diffuser
Solutions for microbial sampling Page 6 of 6
adapter head is shown in two views above, showing the cone shape of the
adapter, and the built-in sample head screen.
The port at the top of the cone is used to connect flexible tubing to the outlet
of the High Pressure Diffuser, such as the Climet CI-302 diffuser. The Bev-A-Line
XX tubing is supplied with the diffuser.
