Bacterial Growth Curve Model Manufacturer,Supplier and Exporter in India
Product Code : EL-BE-6173
Jlab Export is a leading Bacterial Growth Curve Model Manufacturer,and suppliers in India
Bacterial Growth Curve Model (code EL-BE-6173) is a microbiology teaching model of the growth curve of a bacterial culture — the lag, log, stationary and death phases that follow when bacteria are put into fresh medium in a closed vessel. It gives students a reference before and after bacteria culture experiments in school and college labs. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is the Bacterial Growth Curve Model Used For?
When bacteria are inoculated into a fixed volume of broth and nothing is added or removed, the number of living cells, plotted on a logarithmic scale against time, follows a characteristic curve:
- Lag phase — cells adjust to the new medium and make the enzymes they need; there is little or no division yet.
- Log (exponential) phase — cells divide by binary fission and the population doubles every generation time, giving a straight line on the log plot.
- Stationary phase — nutrients run short and wastes build up, so new cells roughly balance those dying.
- Death (decline) phase — more cells die than are formed.
The model links directly to the syllabus. NCERT class 11 uses the same lag, log and stationary phases to describe geometric growth and the sigmoid curve, and NCERT class 12 contrasts exponential (J-shaped) with logistic (S-shaped) population growth. In the lab, students follow a real culture by viable plate counts or by turbidity readings in a colorimeter, and the model helps them read their own graph.
Frequently Asked Questions
Why does a bacterial culture stop growing?
In a closed vessel the nutrients are used up and toxic wastes accumulate, so the culture moves into the stationary and then the death phase.
Why is the curve drawn on a log scale?
Because growth is exponential: a log scale turns the doubling population into a straight line, which makes the phases and the generation time easy to read.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of microbiology lab equipment and biology models in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. Models are made in JLab’s own works rather than bought from traders, so schools, colleges, dealers and importers get them direct from the maker. JLab exports worldwide and ships to buyers in every region — for example Qatar in the Middle East, Vietnam in Southeast Asia, South Korea in East Asia, Belize in Central America and the Caribbean and Liberia in West Africa.
Equipment for a Growth Curve Practical

- Digital Colorimeter — measures how much light a sample absorbs, for turbidity readings.
- Petri Dish — borosilicate glass dishes for growing cultures on agar.
- Inoculation Needle — a metal needle for bacteriological work.
