Tulgren Funnel
Product Code : LSK-BL-10206
Tulgren Funnel (SKU LSK-BL-10206), more widely spelled Tullgren funnel, extracts small animals from a soil or leaf-litter sample. The sample rests on a perforated plate under a heating lamp, and the warmth and drying drive the organisms down through the funnel into a collecting jar. It serves ecology fieldwork in senior school biology, B.Sc. zoology and environmental science courses. Science Lab Supplies arranges supply from Ambala, India, quoting single funnels or class sets for schools, colleges, stockists and tender contractors.
Specifications
The Tulgren Funnel pairs a 175 mm diameter funnel with a 170 mm diameter sieve that is 65 mm deep. In short, coarse and fine mesh are supplied for different soil types, a horizontal support rod and bosshead come with it, and the lamp above takes a B22D bayonet bulb of 40 W or less.

Applications and Experiments for the Tulgren Funnel
The funnel reveals mites, springtails, larvae and other small invertebrates that are hard to pick out of soil by eye. It supports soil-organism and ecosystem topics in NCERT Class 12 biology, B.Sc. zoology and ecology practicals, and field projects in environmental science programmes.
- Class 12 ecology: comparing the animals extracted from garden soil, leaf litter and compost, with the funnel held on a Laboratory Retort Stand.
- Collecting the extracted organisms in a small jar such as the 60 ml Glass Bottle, Wide Mouth.
- B.Sc. zoology: sorting and identifying soil fauna under a Student Stereo Microscope.
- Ecology projects: relating soil animal counts to the plant cover recorded in a quadrat.
The lamp runs on 220 V mains, so students should set it up under teacher supervision and keep the bulb clear of dry leaf litter.
Standard Scope of Supply
Each Tulgren Funnel comes with its sieve, coarse and fine mesh, a horizontal support rod and a bosshead. The low wattage B22D bulb, the specimen collection container and the retort rod and base are not included; a stand and collecting bottles can be added to the same quotation.
Packing, MOQ and Lead Time
You can request a price for one funnel or for a set covering every group in an ecology practical. Each quotation from Science Lab Supplies gives the packing, delivery time and price for that number, and retort stands or collecting bottles can share the same quote.
Science Lab Supplies holds an Importer-Exporter Code and is able to ship to buyers in Egypt, Iraq, Nigeria, Kenya, Ghana and Ethiopia. Questions about quantities go through the contact page; you can also build a list in the enquiry cart or follow the lab tender page for institutional bids.
Frequently Asked Questions
How does a Tulgren Funnel work?
A soil sample is placed on the perforated plate and a heating lamp is held above it. As the top of the sample warms and dries, the organisms move downwards, pass through the funnel and drop into a collecting jar.
Which bulb does the lamp need?
It needs a low wattage bulb with a B22D bayonet fitting of 22 mm diameter, rated at 40 W or less, for 220 V operation. The bulb is not included with the funnel.
Why are two meshes supplied?
Coarse and fine mesh are both included, so the sieve opening can be chosen to suit the soil or litter sample and the size of the organisms that the class wants to extract.
Who supplies the Tulgren Funnel?
Orders are handled by Science Lab Supplies in Ambala, India. The team prices the funnel for schools, colleges, distributors and tender buyers and can combine it with stands, collecting jars and field ecology items in one shipment.
