Colony Counter Manufacturer,Supplier and Exporter in India

Colony Counter (Product Code: SCI-2429/036) is a digital instrument used to count bacterial and mould colonies on petri dishes in microbiology teaching and testing laboratories. College students and lab staff touch each colony with a felt-tipped electronic pen, and pressure-sensitive counting adds it to a 3-digit LED display reading 0 to 999, with an audible confirmation. This digital colony counter is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Colony Counter Used For?

Plate counts sit at the heart of many practicals: estimating viable bacteria in water, milk or soil dilutions, comparing growth on different media, or showing how a disinfectant reduces survivors. After incubation the dish goes on the counting cell, the background is switched to light or dark to suit the colony colour, and each colony is touched with the pen. The felt tip leaves a dot so the same colony is not counted twice, while the counter adds one and beeps.

Press zero before starting each new plate, use count correction to remove a mistaken touch, and use the average count facility when a group counts replicate plates from the same dilution. Choosing a dilution that gives well-separated colonies makes counting quicker. The simple interface makes it a practical piece of microbiology lab equipment for student benches as well as routine laboratory work.

What to Specify When Ordering

• Quantity, for example one counter per bench group or one per lab.
• Your mains supply, since the listed electrical supply is 240 V.
• The petri dish diameters you use, to confirm they fall within 50–100 mm.
• Whether spare pens should be quoted — ask us.

Frequently Asked Questions

How high can the Colony Counter count?
The Colony Counter displays counts from 0 to 999 on a 3-digit LED display. Each pressure-sensitive touch of the electronic pen adds one colony, an audible signal confirms it, and the count correction feature removes a mistaken entry.

What petri dish sizes fit the Colony Counter?
The Colony Counter accepts petri dishes from 50 to 100 mm in diameter. The dish rests on the counting cell, and a light or dark background can be selected so that pale or dark colonies stand out clearly.

How does the Colony Counter pen prevent double counting?
The Colony Counter's electronic pen carries a felt marker, so each touch on the petri dish registers a count and leaves a dot on that colony. Marked colonies are easy to skip, which helps students avoid counting the same colony twice on crowded plates.

What power supply does the Colony Counter need?
The Colony Counter is listed for a 240 V electrical supply. If your laboratory runs on a different mains voltage, state it in your enquiry so we can confirm suitability before the quotation is issued.

Who supplies the Colony Counter?
The Colony Counter is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. Laboratories, colleges, dealers and importers receive quotations from the company and can ask it about repeat orders, replacement pens and spare parts.

Is a calibration certificate available for the Colony Counter?
Discuss any calibration-certificate requirement for the Colony Counter with us before ordering. State the document you need when you enquire through the contact page, and we will confirm what can be provided with your quotation.
