Description
A 150 mm conical glass funnel with a long drawn stem. The extended stem is the point of it: it reaches down inside the neck of a small-mouthed bottle or volumetric flask, so liquid is delivered below the neck rather than running down the outside.
The funnel has a plain stem with no ground-glass joint, so it can be used loose in an open neck, in a funnel ring or clamped in a stand. Nothing about the design restricts it to a particular vessel.
Specification
- Top diameter: 150 mm
- Form: conical funnel with a long drawn stem
- Stem: plain, no ground-glass joint
- SKU: GF-150
If you need a funnel that mates directly to a standard-taper socket, see the 24/40 jointed glass funnel listed separately.
Frequently asked questions
Does this funnel have a ground-glass joint?+
No. The stem is plain and drawn to a long taper. It rests in an open neck, a funnel ring or a clamp. If you need a funnel that seats directly into a 24/40 socket, we list a separate jointed version.
What does the 150 mm figure refer to?+
The top diameter of the cone. It is the dimension that determines how much you can pour in at once and whether the funnel will sit in a given ring or holder.
What glass grade is it?+
The supplier listing specifies it only as glass and does not state a borosilicate grade or a thermal-shock rating. We are not going to quote one that has not been published. If your application depends on thermal or chemical resistance, ask us to confirm the grade in writing before ordering.
What is it used for?+
General transfer of liquids into containers, and specifically into small-mouthed bottles and flasks where the long stem clears the neck. It is not a filtration funnel: there is no plate, frit or paper support.
Is it supplied singly or in a set?+
Singly. SKU GF-150 is one funnel.
