General Description

The Colony Counter consists of an illuminated receiver plate and a large LED display (see Fig. 1). The
pressure of marking a colony with a felt-tip pen registers a count by an audible bleep and advance on
a digital display. A built-in averaging facility allows multiple plates to be counted and then the average
colony count calculated.

A choice of light or black background is available and the pressure required to register a count can
be adjusted. The unit is supplied complete with one Wolffhuegel graticule, segmentation disc and
centering adapters for 50-90mm dishes. A printer and a magnifier for counting very small colonies are
available as accessories. Counting results may also be sent to a computer via USB.

Safety Advice

Users should be aware of the following safety advice:

❖ The unit should be carried using both hands with the fingers under the side edges.

❖ NEVER move or carry the unit with containers on the top or while still connected to the power

supply.

❖ In case of power interruption, a fault or mechanical failure, the unit will continue to operate on

removal of fault.

❖ DO NOT position the unit such that it is difficult to disconnect it from the power by removing the

power cable from the socket at the back.

Operation

Setting Up the Colony Counter

To select either the dark or white background, slide the panel, which can be found underneath the
unit (see Fig. 3), to the left or right until the background clicks home into place. To use a petri dish of
less than 90mm (3.5 in.) in diameter, select the appropriate adapter, which can also be found on the
underside of the unit (see Fig. 3) and place on the receiver plate.

The Colony Counter is provided with a pack of clear discs, designed to protect the receiver plate
from dust and scratches. Place a disc in the receiver plate. If this becomes damaged, remove and
replace with another. If the Wolffhuegel graticule or segmentation disc is required, place on top of the
clear protective disc on the receiver plate.

Position the unit on a firm level surface. The sensitivity control dial, located at the back of the unit (see
Fig. 2), can adjust the pressure required to register a count. Turning it clockwise will increase the
sensitivity, turning it counter-clockwise will decrease the sensitivity.
