Product Code : EL-SLE-4767
Jlab Export is a leading Colony Counter (4 Digit) Manufacturer,and suppliers in India
Colony Counter (4 Digit) (code EL-SLE-4767) is a bench counter for bacterial colonies and cells on culture plates in microbiology labs. Each colony is marked with an auto marker pen, an audible signal confirms the count, and a 4-digit display keeps the running total, while a 110 mm diameter magnifying glass and a Wolffhügel glass grid help the user see and section the plate. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

Choose this model for straightforward plate counting with a large magnifier and a 4-digit total. The digital and microprocessor counters are listed with LED illumination and longer readouts, and the microprocessor model adds count correction, averaging and storage for labs that log many plates.
What Is a Colony Counter Used For?
After a diluted sample has been spread or poured on agar in a Petri dish and incubated, every visible colony is taken to have grown from one viable cell or cluster. Counting them — the standard plate count — and multiplying by the dilution factor gives the number of colony-forming units in the original sample. College and university microbiology practicals, and labs testing food, dairy products and water, all rely on this count. With this instrument the user looks at the plate through the magnifier and touches each colony with the marker pen: the dot on the dish shows which colonies are done, the beep confirms each count and the display keeps the total. On crowded plates the Wolffhügel grid divides the area into squares so that representative squares can be counted and the total estimated.
Wipe the grid and magnifier with a soft lens cloth, keep culture plates closed while counting, and follow your lab’s biosafety rules for disposing of the dishes afterwards.
What to Specify When Ordering
- Quantity — the minimum order is 10 units.
- Power supply — state your mains voltage and plug type so JLab can confirm the version supplied.
- Petri dish size — give the dish diameter you use so the fit on the counting area can be checked.
- Consumables — Petri dishes and spare marker pens can be added to the same enquiry.
Frequently Asked Questions
How does this colony counter register each colony?
You mark each colony with the auto marker pen; the counter registers it, gives an audible confirmation and adds it to the total on the 4-digit display, while the ink dot shows which colonies have already been counted.
What is the Wolffhügel grid for?
It is a ruled glass grid that divides the plate into squares. On dense plates you count colonies in a selection of squares and scale up to the whole plate instead of counting every colony.
How large is the magnifier?
The magnifying glass is 110 mm in diameter, large enough to view much of a standard plate at once.
Does it have built-in illumination?
The listing for this model does not mention illumination. If you need an illuminated counting area, ask JLab, or compare the digital and microprocessor colony counters, which are listed with LED illumination.
Are Petri dishes or culture media included?
No. The listing covers the counter; Petri dishes are a separate item and can be quoted together with it.
What is the minimum order and dispatch time?
The minimum order is 10 units. Dispatch is usually within 7–10 working days, every counter is visually inspected before packing, and export transit time depends on the destination.
What information is needed for an export quotation?
The quantity, destination country and port or city, preferred delivery terms such as FOB or CIF, your mains voltage, any packing or labelling needs, and the tender reference if there is one.
Who manufactures this colony counter?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India, and quotes for it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a microbiology, biology and general laboratory equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The colony counter is built at JLab’s own works rather than bought in from a trader, so colleges, research and testing labs, dealers and importers buy it factory-direct; every unit is visually inspected before dispatch, and repeat orders and spare pens are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Moldova in Eastern Europe, Algeria in North Africa, the Maldives in South Asia, Botswana in Southern Africa and Cameroon in Central Africa. Tender buyers will find details on the JLab lab tenders page.
