Corning Pyrex 1000ml Glass Beaker with 125mm Watch Glass, Double Scale

Description

Product Overview

The Corning Pyrex 1000ml glass beaker is engineered for demanding laboratory environments where precision, durability, and safety are paramount. Constructed from high‑quality borosilicate glass, the beaker withstands rapid temperature changes and aggressive chemicals, making it suitable for a broad spectrum of experimental protocols. The beaker features a low‑form Griffin design, which provides a stable base and a wide opening for easy sample access and cleaning. Integrated with a 125mm watch glass, the package offers a complete solution for covering and protecting samples during reactions, evaporations, or crystallizations.

Graduated markings are printed on both the interior and exterior surfaces, ranging from 50ml increments up to the full 1000ml capacity. This double‑scale system allows users to read measurements from either side, reducing the chance of misreading and enhancing workflow efficiency. The beaker’s dimensions—approximately 108mm in diameter and 158mm in height—fit comfortably within standard laboratory racks and fume hoods, while the 1.37‑pound weight balances robustness with manageable handling.

Usage

Designed for versatility, this beaker excels in a variety of laboratory settings, including chemistry, biology, and environmental science. Researchers can employ it for solution preparation, titration, heating, and cooling processes, thanks to its excellent thermal shock resistance. The included 125mm watch glass serves as an ideal cover for small-scale reactions, preventing contamination while allowing observation of the reaction progress. In educational labs, the clear visibility of the beaker’s graduations aids students in learning accurate measurement techniques and understanding volume concepts.

Beyond traditional bench work, the beaker is compatible with magnetic stirrers, heating mantles, and rotary evaporators, expanding its utility across complex experimental setups. Its chemical resistance ensures that aggressive solvents such as acids, bases, and organic reagents do not degrade the glass, preserving the integrity of both the beaker and the samples it contains. The ergonomic low‑form shape reduces the risk of spills during transfer, and the sturdy construction minimizes breakage during routine handling.

FAQ

What types of chemicals can this beaker safely hold?

The beaker is made from borosilicate glass, which is resistant to most acids, bases, and organic solvents. It can safely contain common laboratory reagents such as hydrochloric acid, sodium hydroxide, ethanol, and acetone. However, for extremely aggressive chemicals like hydrofluoric acid, a specialized container is recommended.

Can the beaker be used on a hot plate or with direct flame?

Yes, the beaker’s borosilicate composition provides excellent thermal shock resistance, allowing it to be placed on hot plates, heating mantles, or even exposed to direct flame for short periods. Gradual heating and cooling are advised to prevent sudden temperature changes that could cause stress.

Is the watch glass compatible with the beaker for sealing purposes?

The 125mm watch glass is designed to sit snugly on the beaker’s opening, providing an effective seal for small‑scale reactions. While it offers protection against contamination and evaporation, it is not intended for high‑pressure applications. For sealed reactions requiring pressure resistance, a dedicated reflux condenser should be used.

How should I clean and maintain the beaker to ensure longevity?

Cleaning with mild detergent and warm water is sufficient for routine maintenance. For stubborn residues, soak the beaker in a diluted acid solution (e.g., 10% nitric acid) followed by thorough rinsing with deionized water. Avoid abrasive scrubbers that could scratch the glass surface. Proper drying and storage in a protective rack will further extend the beaker’s service life.

What is the warranty coverage for this product?

The beaker comes with a one‑year limited warranty covering manufacturing defects. If the beaker cracks or fails under normal laboratory use within this period, contact our support team for a replacement or refund. The warranty does not cover damage caused by misuse, improper handling, or exposure to extreme conditions beyond the specified limits.
