Don't Let A Leaky Joint Ruin Your Synthesis. In organic chemistry, precision is everything. The Laboy Glass Jointed Powder Funnel is engineered for chemists who demand reliability. Why Precision Matters:In a professional lab, a loose joint means a ruined experiment. While generic budget brands often struggle with consistency, Laboy is engineered to match the heavyweights. Real users report that this funnel fits seamlessly with existing Chemglass and Ace Glass flasks—no wobbling, no leaks, just a perfect seal.Correct Thermal Data for Professionals:We value scientific accuracy. Our Borosilicate 3.3 Glass features a Strain Point of 515 C, Annealing Point of 560 C, and Softening Point of 820 C.The Solution:Whether you are building a new setup or replacing a broken piece in a premium kit, Laboy integrates perfectly. For critical moisture-sensitive reactions, pairing with Laboy Round Bottom Flasks offers the ultimate leak-proof assurance.

  • INTERCHANGEABLE WITH TIER-1 BRANDS: Precision-ground to strict US tolerances. Customers verify exceptional fit and vacuum integrity even when paired with premium industry-standard glassware like Chemglass, Ace Glass, and Corning. Get the professional reliability of top-tier brands at a fraction of the cost.
  • SCIENTIFICALLY ACCURATE THERMAL SPECS: Made of authentic Borosilicate 3.3 Glass. Annealing Point 560 degrees Celsius, Softening Point 820 degrees Celsius. Engineered to withstand rapid thermal shock and direct heating better than standard soda-lime or generic laboratory glass.
  • CLOG-FREE POWDER TRANSFER: Features a scientifically optimized 60-degree angle and wide-bore short stem design. Allows sticky powders and viscous reagents to flow freely into your reactor without bridging or blocking the joint. 50mm top diameter is ideal for precise, small-volume transfers.
  • HEAVY-DUTY DURABILITY: Features a reinforced rim and heavy-wall construction. Designed to survive the daily rigors of a busy lab, reducing breakage rates compared to standard thin-wall funnels. Meets ASTM E438 specifications for professional laboratory use.
  • OPTIMIZED SYSTEM PERFORMANCE: While compatible with all brands, this funnel is the Gold Standard match for Laboy Flasks. Users report that maintaining a single-brand ecosystem significantly reduces the risk of frozen joints or vacuum leaks often caused by mixing manufacturers with varying quality controls.
