Glass Erlenmeyer Flask 1000ml 4 Pack – Tellegloww Conical Screw Cap

Description

Product Overview

The Tellegloww 4‑Pack Glass Erlenmeyer Flask set delivers a professional‑grade laboratory solution designed for both educational and research environments. Each flask holds a generous 1000 ml (33.8 oz) of liquid, offering ample capacity for a wide range of experiments, from titration and synthesis to culture media preparation. Crafted from high‑quality soda‑lime glass, the flasks provide excellent chemical resistance, thermal stability, and durability, ensuring they can withstand repeated heating, cooling, and cleaning cycles without compromising structural integrity. The conical shape promotes efficient mixing and easy pouring, while the permanently etched white enamel graduations deliver clear, fade‑resistant volume markings that remain legible even after extensive use. Each flask is equipped with a GL45 blue screw‑cap made from polypropylene, providing a tight, leak‑proof seal that protects samples from contamination and evaporation. The set includes four individually packaged flasks, each wrapped in a protective foam bag to prevent breakage during shipping and handling. Dimensions measure approximately 8.27 inches in height with a base diameter of 4.92 inches, and each unit weighs about 5.38 pounds, making them sturdy yet manageable for routine laboratory tasks.

Usage

These versatile Erlenmeyer flasks are ideal for a broad spectrum of scientific applications. In high‑school chemistry classrooms, they serve as reliable vessels for conducting classic experiments such as acid‑base titrations, precipitation reactions, and solution preparation, allowing students to develop hands‑on skills while observing clear volume markings. In university laboratories and research institutions, the 1000 ml capacity accommodates larger reaction volumes, making them suitable for synthesis, extraction, and crystallization procedures. The robust glass construction tolerates moderate heating on hot plates or water baths, enabling temperature‑controlled reactions, while the secure screw‑cap ensures that volatile or hazardous substances remain contained. Microbiology labs benefit from the flasks’ ability to store culture specimens and media, as the screw‑cap provides an airtight environment that minimizes contamination risk. Additionally, the flasks are compatible with standard laboratory accessories such as magnetic stir bars, clamps, and stands, further expanding their utility across diverse experimental setups.

FAQ

What types of chemicals can these flasks safely hold?

The soda‑lime glass construction is compatible with most aqueous solutions, organic solvents, acids, and bases commonly used in laboratory settings. However, for highly corrosive substances such as hydrofluoric acid, a specialized glass type is recommended.

Can the flasks be used on a hot plate or in a water bath?

Yes, the flasks can tolerate moderate heating. They are suitable for use on hot plates, water baths, and oil baths up to temperatures typically encountered in standard laboratory procedures (approximately 200 °C). Sudden temperature shocks should be avoided to prevent thermal stress.

Are the screw caps compatible with standard laboratory clamps?

The GL45 caps are designed to fit standard 24‑mm screw‑thread clamps and can be securely attached to most laboratory stands and racks. This compatibility ensures stable positioning during mixing, heating, or storage.

How should the flasks be cleaned after use?

Rinse the flasks with distilled water followed by an appropriate cleaning solution (e.g., laboratory detergent). For stubborn residues, a gentle brush or ultrasonic cleaner can be used. Rinse thoroughly and allow to air‑dry before the next use.

What is the warranty policy for these flasks?

Tellegloww offers a one‑year limited warranty covering manufacturing defects. If a flask arrives damaged or exhibits a defect during normal use, contact our customer service team with the order details and photos of the issue for a replacement or refund.
