In various research activities, taking total microbial
count is a regular procedure. A major tedious task that
requires attention on microbiological aspects is to
simplify enumeration of bacteria colony number.
Counting colonies using traditional manual methods
were tiresome tasks requiring high levels of
concentration. For these purposes colony counter
machines provide an alternative, simplified and accurate
solution. A colony counter is an instrument used to
count colonies of bacteria or other microorganisms
growing on an agar plate. HiMedia's Colony Counter
(LA660) allows the user to quickly and accurately
enumerate bacterial and yeast colonies. These counters
are lighted surfaces on which the plates are placed, with
the colonies marked off with a felt-tipped pen on the
outer surface of the plate while the machine keeps the
count. Simplification of the process and acquiring the
bacterial count accurately and consistently is thus made
possible.

c)
Magnifying lens
Warranty certificate
Instruction Manual.
Colony Counter will operate under most normal
conditions, but should not be exposed to moisture or
extreme variations in temperature.
Connect the power cord to the Instrument and the
Plug to an EARTHED three-pin mains socket,
supplying 230V AC, 50Hz, single phase.
Screw the Lens Holding Rod on the Lens Holding
Base on the Instrument and tighten with the help of
the L handle placed behind the instrument.
Slide the Magnifying Lens on it. Focus the Lens by
sliding up or down and tighten at desired level,
taking care to leave enough height below the lens to
be able to use the Pen.

Operating Procedure
Turn ON the Instrument by pressing the On/Off
Switch.
Place the Petri Plate on the Glass grid.
register a count, there will be a beep and an ink dot
will be marked on the Petri Dish. Continue till all the
colonies are thus counted.
As a colony is marked with ink while it is being
counted, missing a count or double counting is
avoided. When the counting is completed. Note the
reading on the counter.
The COUNT push button switch (next to the RESET
switch) may be used to count sparsely populated
plates or for some other counting purpose also.
To Avoid contamination of the petri plate by pen
marker,counting can be done in either of the
following methods :
a) If the Petri Plate is finely plated (thin layer) then it
can be kept upside down, and marking can be done
on the bottom side (which is now on top)
b) The lid can be kept over the plate and marking
may be done on the glass cover. But in this case, as
there is a gap between the media and the marking,
the counting should be done in one sitting without
altering the view angle or moving/ turning the plate
or it scover.
Keep the cap on the probe when not in use.
NOTE: The special feature of this instrument is that you
can use any hard tipped marker pen. You are not limited
to using a proprietary pen.
