Investigating Spontaneous Generation Lab Investigation Manufacturer,Supplier and Exporter in India

Investigating Spontaneous Generation Lab Investigation (Product Code: SLE/EB/17) is a microbiology class activity used to recreate Louis Pasteur's 1864 experiment and test whether life can arise from non-life in school biology labs. Students compare organisms grown in flasks open to airborne particles with flasks that have special S-shaped necks, and the activity is designed for a class of 40. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a microbiology teaching kit that joins lab skills with the history of science.

What Is the Spontaneous Generation Investigation Used For?

It is used to let students test one of biology's oldest questions with their own eyes. Nutrient broth is sterilised in both kinds of flask, which are then left side by side while students check them regularly for cloudiness, the usual sign of microbial growth. The open flasks, reached by dust and airborne particles, cloud over; the S-neck flasks, where particles settle in the bend of the neck, stay clear even though air can still reach the broth. Students record their observations in a table and explain the difference.

The discussion that follows is the real payoff. Students see why Pasteur's design answered the critics who said boiled broth lacked “air”, and why the result supports the idea that microbes come only from other microbes, giving firsthand insight into ideas that underpin evolution. As a bacteria culture experiment it also introduces sterilisation, contamination and controls — ideas students will need in every later microbiology practical.

Related Laboratory Equipment

Useful additions for preparing and running the flasks:

• Autoclave, Stainless Steel, 15 Litre — sterilises the nutrient broth and glassware before the flasks are set up.
• Incubator 30L, upto 80C — keeps the flasks warm so that growth in the open flasks appears sooner.
• Spirit Lamp — a simple flame source for heating and careful handling during set-up.
• Microbe Scavenger Hunt — a follow-on activity in which students look for microbes in air, water, soil and food.

Frequently Asked Questions

What does the Investigating Spontaneous Generation Lab Investigation demonstrate?
The Investigating Spontaneous Generation Lab Investigation demonstrates that microorganisms in a sterilised nutrient broth do not appear spontaneously, recreating Pasteur's 1864 result that growth follows only when particles from the air can reach the broth.

What class size is the Investigating Spontaneous Generation Lab Investigation designed for?
The Investigating Spontaneous Generation Lab Investigation is designed for a class size of 40 students, so a single order covers a typical class working in groups around the open and S-neck flasks.

Are the S-neck flasks and the broth included?
Please ask us for the current contents list of the Investigating Spontaneous Generation Lab Investigation, including whether nutrient broth is supplied. The activity is built around open flasks and flasks with special S-shaped necks, exposed to air but not to particles.

How long does any nutrient broth supplied with the investigation keep?
No fixed period is stated for media used in the Investigating Spontaneous Generation Lab Investigation, because shelf life depends on the chemical, its grade and storage conditions. Ask us for the expiry date of the batch you are quoted.

How long before results can be seen?
In the Investigating Spontaneous Generation Lab Investigation, growth in the open flasks usually becomes visible within a few days, depending on room temperature; keeping the flasks in an incubator can speed this up.

Is the practical safe for schools?
Yes, the Investigating Spontaneous Generation Lab Investigation is suitable for schools with normal microbiology hygiene: avoid opening or tipping the flasks once growth appears, and sterilise all cultures before disposal.

Who supplies the Investigating Spontaneous Generation Lab Investigation?
Jain Scientific Equipments Pvt Ltd, trading as ScienceLab from Ambala, Haryana, India, supplies the Investigating Spontaneous Generation Lab Investigation to schools and colleges in India and international markets, and quotes directly for single classes or several schools.
