The Reichert Darkfield Quebec colony counter provides efficient, accurate and convenient colony counting at an affordable cost for clinical, veterinary, industrial and classroom laboratories
Even, glare-free illumination over the entire culture plate and the use of Reichert's reknowned optics assures clear, quick results which provides outstanding value for laboratory technicians and teachers who require a manual counting platform.
A highly polished glass, annular reflector spreads light from a 40watt bulb uniformly over the entire plate area.
Contrasted against the darkfield background, colonies of any type are bright and readily distinguished from other structures in the culture plate media.
Two different models offer an economical means for any research laboratory or clinical testing lab to analyse bacterial or other types of colonies in the areas of clinical and research microbiology, molecular biology, genetics research, virology, as well as a teaching tool for biology labs in schools and colleges.
The model 13332600 is designed for manual counting and recording using a dish holder accomodating up to 100mm diameter round dishes or 100x100mm square dishes with a magnification lens of 1.5x which can be raised and lowered for optimal focusing.
The lens can also be rotated to allow easy access to the culture plate.
An optional additional 1.5x lens can increase total magnification to 3x.
Even the viewing angle of the plate can be adjusted using built-in tilt legs in the back or front.
A white-ruled Wolfheugal-version counting plate is included.
The model 13332800 includes all the features described above plus an automatic recording feature.
Using the counting probe included, each time a colony is touched in an open dish, the instrument's digital counter automatically records the colony.
By touching the colony, the conductive surface of the agar completes an electrical circuit which activates the counter.
If the dish must be closed for sterility or for biohazard reasons, an optional hand-held push button counter may be used.
The Darkfield Quebec colony counter was designed to be simple-to-use, but also with many thoughtful and practical features that allow it to stand clearly above others and become a favourite in labs everywhere.
