Counting colonies with the unaided eye is a slow, tedious, and sight-damaging task. IULs colony counter makes this process easier and faster through the use of LED lighting and a high-quality magnifying glass. Any microbiology lab involved in colony counting will find this tool absolutely vital. Petri plates are inserted inside the colony counter where they are properly lit and magnified. Operators can tick detected colonies with a specifically devised marker, meanwhile a digital display increases the total counts. Pointers that can directly contact colonies are also available.
