Digital Colony Counter
Digital Colony Counter (Product Code: SLE/LI/02) is a bench instrument used to count bacterial and fungal colonies on Petri dishes in microbiology, food, water-testing and teaching laboratories. It keeps a running total on a 4-digit LED display with hold and count-correction functions, and a x1.7 magnifier lens helps with small colonies on 110 mm dishes. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, for buyers of microbiology lab equipment in India and abroad.

What Is a Digital Colony Counter Used For?
After incubation, each visible colony on an agar plate represents a colony-forming unit, and counting them gives the microbial load of the original sample. A digital colony counter speeds up plate counts for drinking water, milk and food testing, antibiotic and disinfectant trials, and undergraduate microbiology practicals. Marking each colony with the pen as it is counted prevents double counting, and the count-correction facility removes accidental entries.
Place the dish upside down so you mark the base, not the lid, and work systematically across the plate in sectors. Keep the magnifier lens clean and free of fingerprints. Wipe the pen marks off the dish afterwards if the plate is to be examined again.

Frequently Asked Questions
What is the count range of the Digital Colony Counter?
The Digital Colony Counter (SLE/LI/02) counts on a 4-digit LED display with a listed range of 0 to 9999. Its specification table also mentions 999 maximum count, so please confirm the counting limit of the quoted unit with us before ordering.
Does the Digital Colony Counter keep counts after a power cut?
Yes. The Digital Colony Counter restores its data even after a power failure, and it offers hold and count-correction facilities along with 125 memory, so an interrupted plate count does not have to be started again.
What dish size does the Digital Colony Counter take?
The Digital Colony Counter takes 110 mm Petri dishes and comes with a magnifier lens giving x1.7 magnification, which makes small or closely spaced colonies easier to see and mark accurately.
What is included with the Digital Colony Counter, and how big is it?
The Digital Colony Counter comes with one marking pen and one magnifier lens. It measures about L 210 x B 270 x H 125 mm, weighs about 3 kg and runs on 230 V ± 10% AC, 50 Hz, 40 W.
Who manufactures the Digital Colony Counter?
Jain Scientific Equipments Pvt Ltd (ScienceLab) is the OEM manufacturer of the Digital Colony Counter, producing it at its own licensed factory at Saha, Ambala, Haryana, India, and supplying it directly to laboratories, dealers and importers.
