Funnel with stem Quartzware

The Quartz Funnel with Stem is a precision-engineered piece of high-purity quartz laboratory equipment, designed for the safe and efficient transfer, filtration, or decantation of chemicals, solutions, and powders. Made from fused quartz (≥99.99% SiO₂), it offers outstanding thermal, mechanical, and chemical durability, making it superior to glass funnels in high-temperature, high-purity, or highly corrosive environments. This funnel features a smooth conical bowl and an elongated, narrow stem to ensure controlled, spill-free flow into flasks, beakers, or columns. Quartz construction enables its use in applications requiring optical transparency to UV radiation, as well as resistance to sudden temperature changes and aggressive chemical reagents, such as strong acids and oxidizers (excluding hydrofluoric acid). Ideal for cleanrooms, semiconductor processing, pharmaceutical production, and trace-level chemical analysis, this funnel provides uncompromising reliability and repeatability.
