PSF series automatic colony counters can quickly and automatically measure the number of colonies present in a set area under the specified measurement conditions by means of image processing technology. It solves the problems of long time spent on manual counting, inconsistency of visual measurement, low accuracy of measurement, and inability of color separation of existing measurement equipment.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

uniform illumination<\/h3>

In terms of hardware, with our original illumination technology, a uniform background can be obtained under both bright field and dark field conditions.\nIn addition, using this software, it is also possible to correct the uneven brightness of the culture base itself, and to make the background uniform in all areas except for colonies.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Height-adjustable upper lighting<\/h3>

Upper illumination is required for samples whose culture medium is not transparent to light, or for detecting colonies by color.\nThe height position of the upper illumination can be changed. With this function, the outline of the colony can be clearly photographed.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Manual Calibration<\/h3>

After automatic counting, manual calibration is also possible.\nThe manual correction in the PSF series has three functions: adding false negative colonies, deleting false positive colonies or deleting part of the counting area. The operation is easy to perform with the mouse.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Generally only the surface of the sample table needs to be cleaned. The lighting system is LED and needs to be replaced after about 40,000 hours. Because they are the normal commercial version, they are very low cost and easy to replace.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

Since you can set various sizes of concentric circles on the PSF series, there is no problem.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

Yes, you can, the report format is built into the software. It is possible to transfer data to the format, in addition to saving the data in csv format and saving the image in bmp, gif, jpg or tif format.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

No, it is not possible to automatically detect colonies in the entire area of the petri dish. It is necessary to set the measurement area in the part of the petri dish where the culture medium becomes higher at the periphery of the petri dish. However, the number of colonies in the measurement area can be converted to the total number of colonies in the whole petri dish.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

It's okay.
It is possible to measure opaque media using upper illumination.
The height position of the upper lighting can be changed.
With this function, the outline of the colony can be clearly photographed.
However, height adjustment of the upper lighting is only available in the PSF-2100.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

There are two types of plates: for colony counters and for the measurement of the ring of inhibition.
Both can issue calibration certificates.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

No autofocus function.
However, the depth of field of the PSF series is approximately \u00b150mm.
As a result, it is not necessary to adjust the focus during normal measurement.
Note: Depth of field is the area in front of and behind the point of focus where the subject is in focus.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n

You can output the measurement results in excel format and the measurement conditions in xml format.
To import the format into LIMS, contact the provider.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n <\/div>\n <\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
