Description
Glass vacuum filtration assembly joined by a 40/38 ground glass joint, listed in four sizes.
- 500 mL / 0.5 L (GVF-GJ-500ML)
- 1000 mL / 1 L (GVF-GJ-1000ML)
- 2000 mL / 2 L (GVF-GJ-2000ML)
- 5000 mL / 5 L (GVF-GJ-5000ML)
- Joint: 40/38 ground glass
The 40/38 joint replaces the rubber stopper or bung used on a conventional Buchner setup, giving a ground glass seal between the funnel and the receiving flask. Any component you intend to mate to the assembly must also be 40/38.
Two limits on what we can tell you from the source data. First, the size figures above are the values on the listing, but it does not state which component they measure. Second, the itemised contents of the kit — funnel, frit porosity, clamp, vacuum adapter and any tubing — are not documented, and neither is the glass grade or a vacuum rating. Ask us to confirm the packing list before ordering.
Frequently asked questions
What sizes are available?+
Four: 500 mL (GVF-GJ-500ML), 1 L (GVF-GJ-1000ML), 2 L (GVF-GJ-2000ML) and 5 L (GVF-GJ-5000ML). The listing does not state which component of the assembly that volume describes.
What is actually in the kit?+
The source listing does not itemise it. Funnel type, frit porosity, clamp, vacuum adapter and tubing are all unspecified. Ask us to confirm the packing list before ordering rather than assuming a standard set.
What is the 40/38 joint for?+
It is the ground glass joint between the funnel and the flask, used in place of a rubber stopper or bung. Anything you mate to it must be the same 40/38 size.
What frit porosity does the funnel have?+
Not documented on this listing. If your filtration depends on a specific porosity grade, confirm it with us first.
What glass grade and vacuum rating apply?+
Neither is documented on this listing. No borosilicate grade and no maximum vacuum figure is published for this item.
Is a vacuum pump included?+
No. No pump is listed as part of this item.
