Product Description
Viscous samples and clean solvent work both benefit from a screen support on an all-glass connection. This 47 mm support base holds a stainless steel support screen and seats into a filter flask through a 40/35 ground glass joint, avoiding stoppers in the vacuum path.
This listing is for Wheaton catalog number 419392: 47 mm Stainless Steel Support Base with 40/35 Joint. The base accepts a stainless steel screen and gasket beneath the membrane, with a funnel clamped above. Its 40/35 outer joint mates with matching filter flasks. Use it to replace a damaged base on a stainless-support, ground-joint assembly, or to build an additional station with compatible funnel, clamp and flask. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
