Manufactured to strict Class A volumetric accuracy, this premium glass flask is an indispensable benchmark instrument for chemistry research, quality control, and testing laboratories.\n\nCrafted from low-expansion Borosil 3.3 borosilicate glass, this 100 ml volumetric flask features a classic pear-shaped body with a long, narrow neck engineered for accurate liquid meniscus alignment. A sharp, durable graduation line is permanently etched around the neck to indicate the precise 100 ml fill line at 20°C. The top neck is fitted with an interchangeable, precision-ground glass joint and matching pennyhead glass stopper to form an airtight seal that prevents solution evaporation, splashing during inversion, and contamination.\n\nClass A Volumetric Precision: Individually calibrated for exact volume measurement, meeting international standards for analytical chemistry and quantitative analysis.\n\nBorosil 3.3 Glass Construction: Highly resistant to thermal shock, high heat, and aggressive chemical reagents, acids, and organic solvents.\n\nPrecision-Ground Glass Stopper: Fitted with a tight-sealing ground glass stopper to ensure leak-free mixing and secure short-term solution storage.\n\nPermanently Etched Graduation Line: High-durability calibration mark ensures long-term clarity and easy meniscus alignment without fading over time.\n\nFlat Bottom Design: Provides excellent benchtop stability to prevent accidental tipping during solution filling and mixing.\n\nPerfect for solution preparation, analytical chemistry titrations, precise dilutions, and chemical research applications.","brand":"edumartstore","offers":[{"title":"Default Title","offer_id":47214118666428,"sku":"3","price":325.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0740\/8566\/2908\/files\/LAB.VOL.537233778_1769055790017.webp?v=1785414040","url":"https:\/\/www.edumartplus.com\/products\/borosil-100-ml-volumetric-standard-flask-class-a-high-precision-borosilicate-glassware-with-ground-glass-stopper","provider":"edumartstore","version":"1.0","type":"link"}
