Ensure maximum safety and rapid solvent processing with Heathrow Scientific Heavy-Wall Glass Filtering Flasks. Specifically engineered for demanding vacuum filtration protocols in analytical chemistry and microbiological testing, these specialized Erlenmeyer-style flasks are built to withstand extreme negative pressure differentials. Manufactured from exceptionally thick borosilicate glass, the heavy-wall construction completely prevents implosion and catastrophic structural failure when connected to a strong laboratory vacuum pump.
Each flask features a robust, integrated glass side-arm barb designed to securely grip standard heavy-wall vacuum tubing without snapping or leaking under pressure. When paired with a Buchner funnel and a vacuum source, these flasks drastically accelerate the separation of solid precipitates from liquid filtrates. The wide, flat base ensures total stability on the benchtop, even when top-heavy with fully loaded filtration funnels. Available in capacities spanning from 300 mL up to 2000 mL to accommodate diverse sample processing volumes.
