Glass Erlenmeyer Flask Set 50/150/250ml – Karter Borosilicate

Description

Product Overview

The Glass Erlenmeyer Flask Set from Karter Scientific includes three precisely calibrated flasks with capacities of 50 ml, 150 ml, and 250 ml. Each flask is molded from 3.3 borosilicate glass, a material renowned for its high resistance to thermal shock, chemical corrosion, and mechanical stress. This composition meets ASTM Specification E960, Type I requirements, ensuring that the glass conforms to the most stringent laboratory standards for durability and safety. The flasks feature a tapered neck and a flat bottom, providing a stable base for heating on a hot plate while allowing easy pouring and mixing of liquids. The clear, high‑visibility glass makes it simple to monitor reaction progress, color changes, and precipitate formation. All three sizes share identical design language, creating a cohesive set that simplifies inventory management and reduces the need for multiple product lines.

Key dimensions are as follows: the 50 ml flask has an inner diameter of 24.5 mm and an outer diameter of 30.5 mm; the 150 ml flask measures 32 mm ID and 37 mm OD; the 250 ml flask offers a 32 mm ID and 37.5 mm OD. These dimensions provide a comfortable grip for precise handling while maintaining a compact footprint on the bench. The flasks are supplied in a single set, packaged in a sturdy cardboard box that protects the glass during shipping and storage. The set is listed under the best‑selling category for laboratory Erlenmeyer flasks, reflecting its popularity among researchers, educators, and industry professionals.

Usage

These flasks are designed for a wide range of laboratory applications. In academic settings, they are ideal for teaching basic chemistry techniques such as titration, solution preparation, and reflux. The 50 ml flask is perfect for small‑scale experiments, while the 150 ml and 250 ml flasks accommodate larger reaction volumes, making them suitable for synthesis, crystallization, and kinetic studies. In industrial laboratories, the robust borosilicate construction allows the flasks to withstand repeated heating cycles, making them reliable for quality‑control testing, formulation work, and pilot‑scale production runs.

Because the glass is chemically inert, the flasks can be used with acids, bases, solvents, and organic reagents without risk of leaching or degradation. The flat bottom design enables direct placement on magnetic stir plates, heating mantles, or conventional hot plates, providing flexibility for a variety of experimental setups. The tapered neck facilitates the use of standard laboratory accessories such as stoppers, clamps, and thermometers, ensuring seamless integration into existing workflows.

When working in environments that demand strict contamination control, the smooth interior surface of the borosilicate glass minimizes residue buildup, allowing for easy cleaning and sterilization. The flasks can be autoclaved, rinsed with deionized water, or subjected to solvent washes without compromising structural integrity. This makes them an excellent choice for microbiology labs, pharmaceutical research, and any setting where reproducibility and cleanliness are paramount.

FAQ

Can these flasks be autoclaved?

Yes, the borosilicate glass is rated for autoclaving. It can withstand typical sterilization cycles without cracking or losing dimensional accuracy.

What is the maximum temperature these flasks can handle?

The flasks are safe up to 350 °C (662 °F) when heated gradually, making them suitable for most laboratory heating applications.

Are the flasks compatible with standard stoppers and clamps?

Absolutely. The tapered neck conforms to standard laboratory fittings, allowing you to use common rubber stoppers, glass stoppers, and clamp systems.

How do I clean the flasks after use?

Rinse with deionized water, then wash with a mild detergent or appropriate solvent. For stubborn residues, a brief soak in a dilute acid solution followed by thorough rinsing is effective.

Do you offer bulk pricing for larger orders?
