Utile 8pcs 200ml Glass Erlenmeyer Flask Set Borosilicate Conical

Description

Product Overview

The Utile 8pcs 200ml Glass Erlenmeyer Flask Set is engineered for demanding scientific environments. Each flask is constructed from 3.3 borosilicate glass, a material renowned for its high thermal shock resistance and chemical durability. The uniform wall thickness ensures consistent heat distribution, reducing the risk of breakage during heating or cooling cycles. Graduations are printed directly onto the glass surface, providing clear, easy-to-read volume markings that facilitate accurate measurement without the need for additional equipment. The narrow mouth design minimizes spillage while allowing precise addition of reagents, making these flasks ideal for titration, mixing, and sample preparation.

Beyond the core material advantages, the flasks feature a conical shape that promotes efficient mixing of solutions when gently swirling. This geometry also aids in the collection of precipitates, allowing researchers to observe solid formation without transferring the contents to another vessel. The set includes eight identical 200ml flasks, offering a standardized volume for repeatable experiments and streamlined inventory management in busy laboratory settings.

Each flask meets rigorous laboratory standards, capable of withstanding repeated autoclave cycles at 121°C and 15 psi for at least five minutes. This durability extends the service life of the flasks, reducing replacement costs and supporting sustainable laboratory practices. The flasks are also compatible with a variety of heating methods, including hot plates, heating mantles, ovens, microwaves, and direct flame, providing flexibility for diverse experimental protocols.

Usage

These Erlenmeyer flasks are versatile tools for a wide range of scientific applications. In academic laboratories, they serve as essential equipment for chemistry and biology courses, allowing students to practice fundamental techniques such as solution preparation, dilution, and reaction monitoring. The clear graduations and sturdy construction make them especially suitable for teaching environments where durability and safety are paramount.

In professional research settings, the flasks excel in cell culture work, where the narrow mouth helps maintain sterile conditions while allowing easy access for sampling. The borosilicate composition resists corrosion from common cell culture media, antibiotics, and other reagents, ensuring that the integrity of the culture environment is preserved over extended incubation periods.

For industrial quality control labs, the flasks provide reliable containers for sample collection, analysis, and storage. Their ability to endure high temperatures enables rapid sterilization between uses, minimizing cross‑contamination risks. Additionally, the flasks are suitable for small‑scale synthesis, formulation testing, and analytical chemistry procedures that require precise volume control and robust glassware.

Home hobbyists and DIY scientists also benefit from the set’s user‑friendly design. Whether conducting backyard chemistry experiments, preparing herbal extracts, or exploring basic microbiology, the flasks offer a professional‑grade experience without the need for a full laboratory infrastructure.

Why Choose Us

Utile’s commitment to quality is reflected in every aspect of this flask set. The use of 3.3 borosilicate glass ensures that each flask can tolerate rapid temperature changes without cracking, a critical feature for experiments that involve heating, cooling, or sudden thermal shifts. This material also offers superior resistance to acids, bases, and organic solvents, protecting both the flask and the sample from degradation.

Our manufacturing process incorporates strict quality control checks at each stage, from raw material selection to final inspection. This guarantees that every flask meets exact dimensional tolerances, providing consistent volume measurements across the entire set. The printed graduations are applied using a durable, fade‑resistant ink that remains legible even after repeated autoclaving, eliminating the need for external labeling or replacement.

Customer support is a cornerstone of the Utile brand. We provide comprehensive after‑sales assistance, including guidance on proper cleaning, sterilization, and storage practices. Should any issue arise, our technical team is available to troubleshoot and, if necessary, arrange for replacement parts or a full set exchange under our warranty policy.

Environmental responsibility is also integral to our product philosophy. The flasks are designed for long‑term reuse, reducing waste associated with disposable glassware. By choosing Utile, laboratories can lower their ecological footprint while maintaining high performance standards.

FAQ

Can these flasks be used for high‑temperature heating on an open flame?

Yes, the 3.3 borosilicate glass is rated for direct flame heating. However, it is recommended to pre‑heat the flask gradually to avoid sudden temperature gradients that could cause stress.

Are the graduations calibrated for metric measurements only?

The printed graduations are in milliliters (ml) and are calibrated to standard metric volumes. For users requiring imperial measurements, a conversion chart can be applied, but the flasks do not include printed imperial markings.

How many autoclave cycles can the flasks endure before replacement is needed?

Under normal laboratory conditions, the flasks can withstand at least 50 autoclave cycles at 121 °C and 15 psi without loss of structural integrity or graduation visibility.

Is the set compatible with standard laboratory racks and holders?

Yes, the 200 ml size conforms to common laboratory rack dimensions, allowing secure storage and easy access during routine workflows.

What should I do if a flask develops a chip or crack?

For safety, discontinue use of any damaged flask immediately. Contact Utile customer service for a replacement; our warranty covers defects and damage resulting from normal use.
