The Vacuum Filtering Flask is a robust laboratory glassware item designed for vacuum-assisted filtration procedures in routine and advanced laboratory applications. Manufactured from heat-resistant, durable borosilicate glass in compliance with DIN/ISO standards, it ensures excellent thermal stability, chemical resistance, and long-term durability.

The flask is equipped with a glass side arm compatible with 6–10 mm bore size tubing, allowing secure connection to vacuum sources during filtration processes. Its thick wall construction, heavy base, and reinforced rim significantly reduce the risk of breakage during washing, handling, and transportation, even under reduced pressure conditions.

Clearly visible volume graduations and inscriptions, printed with white enamel, provide easy liquid level monitoring and support reproducible laboratory work. The design makes this flask suitable for use with Büchner funnels and other vacuum filtration accessories commonly used in chemistry, biology, research, and educational laboratories.
