The Triangular Suction Filtration Funnel (also known as a Glass Buchner Funnel with Joint) is a precision laboratory instrument engineered for high-efficiency vacuum filtration. Crafted from premium high borosilicate 3.3 glass, it features a unique inverted conical body with an integrated perforated glass plate for supporting filter membranes or paper. This professional design includes a standard ground joint for a direct, airtight connection to suction flasks and a side-arm nozzle for seamless vacuum pump integration. Its robust construction and superior chemical resistance make it an ideal choice for the rapid separation of solids and liquids in demanding research and industrial applications.

Product Features

Integrated Conical Design: The inverted triangular body ensures optimal fluid dynamics and efficient collection of filtrates during the vacuum process.

Built-in Perforated Plate: Features a precision-drilled perforated glass disc that provides a flat, stable surface for filter paper, ensuring uniform filtration.

Standard Ground Joint: Equipped with a precision-ground standard taper joint (19/26 or 24/29) for a secure, leak-free connection without the need for additional rubber adapters.

Side-Arm Suction Nozzle: Includes a dedicated side arm for quick and secure attachment to vacuum tubing, facilitating easy pressure reduction.

High Borosilicate 3.3 Glass: Offers exceptional thermal shock resistance and superior durability against corrosive acids, alkalis, and organic solvents.

High Transparency: Crystal-clear glass allows for unobstructed visual monitoring of the filtration progress and sample condition.
