Ace Glass Glass Filter Funnel Only Porosity D 7 ml Set of 3 Funnels

Ace Glass Porosity D Glass Filter Funnel, 7 mL Capacity (9727-07) – Set of 3 Funnels

The Ace Glass 7 mL Glass Filter Funnel Only, Porosity D (9727-07) is a high-precision, chemical-resistant laboratory filtration funnel designed for micro-scale analytical preparations, gravimetric analysis, and corrosive chemical separations. Precision-manufactured from high-purity Borosilicate Glass 3.3, this funnel features an integrated fritted glass disc that eliminates the need for filter paper or external support matrices. The Porosity D fritted disc (nominal pore size 10 to 20 µm) provides fine particulate retention while maintaining steady filtration rates under gravity or mild vacuum conditions. Supplied as a set of 3 filter funnels, this reusable glass apparatus is ideal for synthetic chemistry, pharmaceutical QA/QC, and academic research laboratories requiring inert filtration vessels.

Technical Performance & Structural Attributes

• Borosilicate Glass 3.3 Construction: Engineered for high thermal shock resistance, low thermal expansion, and near-universal chemical durability against acids, organic solvents, and neutral solutions.
• Porosity D Fritted Disc (10–20 µm Pore Range): Precision-sintered glass disc captures fine precipitates, micro-crystals, and insoluble impurities without leaching fiber or chemical additives into the filtrate.
• Paperless Micro-Filtration: Reusable fritted glass design eliminates filter paper digestion, fiber shedding, and sample absorption issues during small-volume chemical isolation.
• Straight/Conical Funnel Body: Compact 7 mL capacity reservoir minimizes hold-up volume, enabling high recovery rates when working with expensive or trace-level compounds.
