Schuett Count

Manual colony counter

 

l  three modes of illumination: from below, from the side and from the top (optional)

l  Petri dishes or nutrient disks with Ø 90 mm, Ø 60 mm or Ø 150 mm (optional)

l  high transparency of colonies reached by LED-light source - practically no heat transferred to the sample

l  light intensity, pressure sensitivity for count and acoustical counting signal adjustable

l  average determination

l  data transfer via USB

 

Designed for reliable and efficient counting of bacterial colonies and bacteriophage plaques growing on nutrient agar or nutrient disks/filter disks in Petri dishes.

 

For Petri dishes up to Ø 150 mm.

 

Easy adjustable illumination intensity. Three modes of illumination – sideways from below, sideways from above and top-light (optional).

 

State-of-the-art LED-light allows for glarefree illumination without blinding or straylight. No eyestrain. A sofar unknown transparency and differentiation is obtained. Contrast-disk for counting colonies in light and dark fields for the use with clear or dark agar. Adjustable pressure-sensitivity for counting. Designed for ergonomic and relaxed working.

 

Accurate color re-production makes it easier to distinguish between differently coloured cultures on selective culture media and nutrient disks in food analysis. With process water and waste water, the high contrast illumination simplifies the task of distinguishing between colonies that develop within the agar and colonies that grow on the agar surface.

 

The counting impulse is realized by marking the colonies with an ordinary felt-tip marker pen. An acoustical signal confirms each sound its sound level is individually adjustable.

 

The attachment is equipped with a pen holder.

 

With a 4-digit LED-display (0-9999) and a clearly arranged keypad for all controls.

Schuett colonyQuant

Automated colony counter

 

l  software for selection according to colour, size and shape

l  light-proof sample chamber with CCD-Firewire-camera (colour)

l  image acquisition and simultaneous evalution within seconds

l  tables and images may be stored digitally

l  agar plates, nutrient disks, inhibition zone analysis, spiral plating

l  mixed cultures, up to 8 colours simultaneously per petri dish

l  sectorial evaluation, 90% option

l  in conformity with GLP

 

High throughput analysis of bacterial colonies or bacteriophage plaques in less than a second. The schuett colonyQuant is comprised of a CCD-Firewire camera (colour) with autozoom and autofocus, a light-proof sample chamber and the software for automated colony counting.

 

Differentiation by colour, size and shape to be combined at choice by the user. Additional features allow for separating overlapping colonies. Settings to be stored and retrieved via mouse-click for future analysis of similar type samples. The system is straightforward to use and the software is Windows® based. Results are presented as an image on your monitor or in a table exportable to Excel®.

 

Unique to the schuett colonyQuant is its ability:

 

l  to process up to 400 Petri dishes per hour with up to 1.000 counts per dish.

l  accurate detection of difficult to identify colonies.

l  mixed cultures - differentiation of colonies with up to 8 colours simultaneously.

l  changeover from evaluating agar plates or to nutrient discs, to spiral plates, to inhibition zone analysis etc. can be effected by a simple mouse click.

 

The system has been designed for use with Petri dishes of 60 and 90 mm diameter. As a result of using a LED-array to illuminate the surface of the agar circular from the side a hereto unknown transparency and sharpness for detecting colonies can be observed.

 

Typical applications (examples): Total number of colonies, Enterobacteria, nutrient disks and filter disks, chromogenic agar, high number of colonies (up to approx. 1.000 per Petri dish), bacteriophage plaque assay, inhibition zones and dark agar.
