Streamline your filtration setup with the Laboy Glass Buchner Filtering Funnel. Unlike traditional funnels, this design features an integrated side arm, allowing you to filter directly into any standard flask with a matching joint. **Key Specifications:** - **Capacity:** 150mL - **Joint Size:** 29/42 Standard Taper - **Disc Diameter:** 60mm O.D. - **Porosity:** Coarse G1 (40-60 microns) - **Side Arm:** 10mm (3/8") Hose Barb (Fits 5/16" - 3/8" I.D. Tubing) **Application Note:** The G1 Coarse porosity is excellent for filtering large crystalline precipitates.

  • INDUSTRIAL GRADE BOROSILICATE 3.3: Engineered from premium heavy-wall glass with a low linear coefficient of expansion. Features an annealing point of 560°C, ensuring superior thermal endurance and chemical resistance for rigorous laboratory filtration.
  • INTEGRATED VACUUM SIDE ARM: Features a built-in 10mm (approx. 3/8") O.D. hose barb at the largest serration. We recommend using 5/16" to 3/8" I.D. flexible vacuum tubing to ensure a secure, airtight seal. Allows direct filtration into a standard 29/42 flask.
  • COARSE POROSITY (G1): Equipped with a 60mm O.D. sintered glass frit with G1 porosity (40-60 μm). Ideal for rapid filtration of coarse precipitates, gas dispersion, and coarse gas washing. Provides fast flow rates while retaining larger particles.
  • PRECISION GROUND JOINTS: Features a standard taper 29/42 inner joint, precisely ground to ensure an airtight seal with reaction flasks or boiling flasks. The 60mm disc diameter is compatible with standard 55-60mm filter paper for enhanced particle retention.
  • SAFETY & USAGE: Designed for vacuum filtration applications. While heat-resistant, fritted glassware should not be subjected to direct flame or rapid temperature changes under vacuum to prevent thermal shock. Inspect for cracks before use under pressure.
