Long Stem Funnels Plastic Manufacturer,Supplier and Exporter in India
Product Code : ILS-GPP-11117
Indian Lab Suppliers supplies the Long Stem Funnels Plastic (Product ID: 11117) as part of its general plastic laboratory products range. It is a polypropylene long stem funnel with a 60° cone, smooth inner walls and external ribs that stop air locks, in four diameters from 62 mm to 150 mm.
Quick Answer
The 60° cone angle matches a standard folded filter paper, and the smooth inner walls let liquid run cleanly. External ribs hold the funnel off the neck of the receiving vessel so displaced air can escape, which prevents an air lock that would stall the flow. The translucent polypropylene can be steam autoclaved. Diameters are 62, 75, 100 and 150 mm; listed stem lengths are 67, 69, 84 and 55 mm respectively, so please confirm the stem length of each size at quotation.

Frequently Asked Questions
Why is the cone angle 60°?
A filter paper folded in quarters opens to a 60° cone, so it sits flush against the funnel wall.
What do the external ribs do?
They let air escape from the receiving vessel so the liquid does not stop flowing.
Can it be autoclaved?
Yes, it is steam autoclavable.
