Bright line. With double ruling. Calibratable. Same counting grid as the Improved Neubauer cell, but with rhodium coated chamber base. Rulings are engraved into the Rhodium layer and appear bright under normal microscope settings. By altering the contrast it is possible to reverse the image under the microscope to make the rulings appear brighter or darker as required.

With double ruling. Calibratable. Cell depth 0.1 mm. Same ruling as Improved Neubauer, but the large square in the centre is divided into 16 squares each with a side length of 0.25 mm. Unlike the more modern Improved Neubauer counting chambers, the counting area of each group square is limited by the outermost of the triple border lines.

Adapter for other petri dish sizes on request.

Scan® 300 is an automatic colony counter that includes the essential features for Petri dish counting. It is specifically adapted to the usual media in food microbiology (PCA, MRS...). With a CCD camera with 1 Megapixel - zoom x 28. It counts colonies on a Petri dish in less than half a second, with a minimum colony size of 0.1 mm. For the detection of colonies on round pour, surface, spiral and circle mode plated dishes Ø 55 - 90 mm.Scan® 500 is a high-tech automatic colony counter. It counts colonies on a Petri dish in less than half a second and gives you quick, accurate, complete and traceable reading of the results. With its CCD camera and a powerful software, it connects to a PC via a Firewire connection automatically export results to Excel.Scan® 1200 is a high resolution automatic colony counter that offer quick, and traceable counting results. Widely used in food microbiology, it counts colonies and automatically saves all data to Excel. Equiped with a digital camera and a powerful software, it connects to a PC via a Firewire connection. Scan® 1200 counts all colonies, even on smallest poured, spread and Spiral® Petri dishes; on PetriFilm™ and RIDA™ Count/Sanita-kun™, on filtration membrane and Compact Dry™.
