Borosilicate glass short-stem funnel — 150 mm upper outer diameter, 24/40 ground-glass joint. High-performance, reusable laboratory funnel designed for reliable liquid transfer and reagent addition. Key benefits Precise fit: 24/40 ground-glass joint ensures a secure, leak-free connection to standard 24/40 flasks, condensers, adapters, and reactors. Large opening: 150 mm upper outer diameter makes pouring larger volumes and handling viscous liquids easier with less spillage. Durable material: Made from borosilicate glass for excellent chemical resistance and thermal stability; resists acids, solvents, and routine lab temperature changes. Low dead volume: Short stem minimizes hold-up and reduces loss of valuable reagents while keeping the transfer path compact. Reusable and easy to clean: Smooth glass surface resists staining and contamination, compatible with standard lab cleaning procedures. How this funnel solves common lab problems Reduces spills and transfers faster than narrow-mouth funnels thanks to its wide mouth and controlled short stem. Avoids joint leaks and misalignment that occur with improvised adapters because it uses the standard 24/40 ground-glass interface. Maintains sample integrity: chemically inert borosilicate prevents contamination or reaction with common organic and inorganic reagents. Compatibility and specifications Upper outer diameter: 150 mm Joint type: 24/40 ground-glass joint Stem: short-stem design Material: borosilicate glass (high-performance, reusable) Practical use scenarios Routine reagent addition: Secure the funnel in a 24/40 receiving flask to add solvents or reagents during synthesis with minimal splashing and accurate delivery. Solvent transfers during rotary evaporation setup: Fit the funnel to condensers or adapters with 24/40 joints to top up or change solvents safely. Sample preparation and dilution: Use the wide mouth to decant and dilute concentrated samples into analytical vials or reaction flasks while minimizing transfer losses. Handling notes Inspect ground-glass surfaces for chips before use to maintain a reliable seal. Clean and dry thoroughly between uses to prevent cross-contamination.
