About this item

• Borosilicate construction: manufactured from low-expansion borosilicate glass, offering strong thermal shock resistance and chemical stability for high-temperature filtration and corrosive reagent handling
• 4-piece graduated diameter set: includes four funnels (50 mm, 75 mm, 100 mm, 120 mm) with a standardized 1:1 stem-to-rim ratio, ensuring consistent compatibility with laboratory glassware and filtration assemblies
• 60° filtration geometry: precision-formed 60° cone angle accommodates standard laboratory filter paper, supporting stable seating and efficient gravity or vacuum filtration workflows
• Optimized flow performance: uniform wall thickness and polished stems promote smooth liquid transfer and reduce powder bridging during solid handling and sample preparation
• Laboratory & applied use: suitable for analytical chemistry, clinical laboratories, industrial processing, and controlled culinary applications; each unit inspected for dimensional accuracy and supplied with a 1-year limited warranty
