QWORK Erlenmeyer Flask 3 Pack Clear Scale Plastic 50ml 100ml 500ml

Description

Product Overview

The QWORK Erlenmeyer Flask collection is designed to meet the demanding needs of educational laboratories, research institutions, and hobbyist chemists who require reliable, accurate, and durable glassware alternatives. This three‑pack includes three conical flasks with capacities of 50 ml, 100 ml, and 500 ml, providing a versatile range of volumes for titration, mixing, heating, and storage applications. Each flask is constructed from high‑quality, food‑grade plastic that offers the clarity of glass while eliminating the risk of breakage, making it safe for use in busy classroom environments and on laboratory benches where accidental drops are common.

One of the standout features of these flasks is the clear, graduated scale printed directly onto the transparent walls. The markings are calibrated in milliliters and are easy to read from multiple angles, reducing measurement error and speeding up experimental workflows. The scale includes standard tick marks at regular intervals, allowing users to quickly estimate volumes with confidence. In addition, the flasks are equipped with a sturdy, wide‑base design that enhances stability during mixing and heating, preventing tipping and spillage that could compromise results or safety.

Beyond functionality, the QWORK Erlenmeyer Flasks are engineered for comfort and convenience. The smooth, rounded neck facilitates easy pouring and the addition of stoppers or caps when needed. The clear plastic material is chemically resistant to a broad range of common laboratory reagents, including acids, bases, and organic solvents, ensuring longevity even with frequent use. The flasks are lightweight, reducing fatigue during extended experiments, yet robust enough to withstand the rigors of daily handling.

Dimensions and packaging are optimized for storage and transport. The 50 ml flask measures approximately 7.95 × 5.71 × 4.49 inches and weighs only 6.38 ounces, while the larger 100 ml and 500 ml models maintain proportional scaling for consistent handling. All three flasks are securely packaged together, minimizing the need for separate shipments and simplifying inventory management for educators and lab managers.

Customer feedback highlights the reliability and value of this product line. With an average rating of 4.6 out of 5 stars from 96 reviews, users consistently praise the clear scale, durability, and stability of the flasks. The product has earned a respectable ranking within the Industrial & Scientific category on major e‑commerce platforms, reflecting its popularity among both novice and experienced laboratory practitioners.

Usage

These flasks are ideally suited for a wide range of educational and research scenarios. In high school chemistry classes, students can perform classic experiments such as acid‑base titrations, precipitation reactions, and solution preparation with confidence, thanks to the accurate scale and stable base. College laboratories benefit from the larger 500 ml flask for bulk solution preparation, while the 100 ml flask serves as a versatile intermediate size for a variety of protocols.

Beyond the classroom, hobbyist chemists and DIY scientists appreciate the safety and convenience of plastic flasks that can be used in home labs without the fear of shattering. The clear walls allow for easy visual monitoring of reaction progress, color changes, and precipitate formation, which is essential for troubleshooting and documentation. The flasks also perform well in fieldwork settings where portability and durability are paramount, such as environmental sampling or field chemistry demonstrations.

When paired with standard laboratory accessories—such as magnetic stir bars, heating plates, and rubber stoppers—these flasks integrate seamlessly into existing workflows. Their chemical resistance ensures compatibility with a broad spectrum of reagents, making them a reliable choice for routine analytical procedures, synthesis experiments, and quality‑control testing across disciplines.

FAQ

Can these plastic flasks be used with hot liquids?

Yes, the flasks are made from heat‑resistant, food‑grade plastic that can safely handle temperatures up to approximately 120 °C (248 °F). For applications requiring higher temperatures, a glass alternative is recommended.

Are the scale markings calibrated for metric measurements only?

The printed scale is calibrated in milliliters, which is the standard metric unit for laboratory volume measurements. Users who prefer imperial units can convert the values using a simple conversion chart.

What chemicals are compatible with the plastic material?

The flasks are chemically resistant to most common laboratory reagents, including dilute acids, bases, salts, and many organic solvents. They should not be used with strong oxidizing agents such as concentrated nitric acid or peroxide solutions, as these may degrade the plastic over time.

How should the flasks be cleaned after use?

Rinse the flasks with distilled water immediately after use to remove residues. For more thorough cleaning, a mild detergent solution followed by a final rinse with deionized water is recommended. Avoid abrasive scrubbers that could scratch the clear surface.

Is there a warranty or guarantee for these flasks?

QWORK offers a one‑year limited warranty covering manufacturing defects. If a flask arrives damaged or fails due to a material flaw within the warranty period, contact our support team for a replacement or refund.
