Corning Pyrex 1000ml Erlenmeyer Flask with Rubber Stopper 4980-1L

Description

Product Overview

The Corning Pyrex 1000ml Erlenmeyer Flask is engineered for laboratory professionals who demand accuracy, durability, and safety in every experiment. Crafted from high‑quality borosilicate glass, the flask offers exceptional thermal resistance, chemical inertness, and optical clarity, allowing users to monitor reactions without interference. The narrow mouth design minimizes splashing while the heavy‑duty rim provides a secure grip for easy handling. A precision‑molded rubber stopper fits snugly, creating an airtight seal that prevents evaporation and contamination. The flask is calibrated with clear graduations at 50ml, 250ml, 500ml, 750ml, and 1000ml, enabling quick volume assessments without the need for additional measuring devices. Packaged in a double‑wall, BC‑flute corrugated box, the product arrives protected against impact and moisture, ready for immediate deployment in any laboratory setting.

Usage

Designed for a wide range of scientific applications, this Erlenmeyer flask excels in titration, reflux, heating, and mixing procedures. Researchers in chemistry, biochemistry, and environmental science rely on its robust construction for both routine assays and complex syntheses. The rubber stopper allows the flask to be sealed for distillation or gas collection, while the narrow mouth reduces the risk of accidental spills during vigorous stirring. In educational laboratories, the clear graduations serve as a teaching tool for students learning volumetric techniques, and the sturdy rim withstands frequent handling by novice users. The flask’s 1000ml capacity makes it suitable for scaling up reactions, preparing bulk solutions, or conducting large‑volume extractions, providing flexibility across academic, industrial, and quality‑control environments.
