Glass Scientific Graduated Triangular Conical Flask Chemistry Erlenmeyer Flask with Narrow Neck
This general-purpose Erlenmeyer flask, made from GG-17 borosilicate glass and compliant with ISO 1773 and ISO 24450 standards, is a versatile laboratory workhorse designed for holding, roughly measuring, mixing, heating, and boiling solutions. With approximate graduations, a convenient write-on patch, and excellent thermal and chemical resistance, it serves a wide range of applications across research, educational, and industrial laboratories.
Features：
- Dual Standard Compliance: Conforms to both ISO 1773 (narrow-neck flasks) and ISO 24450 (wide-neck flasks), offering a standardized solution for different laboratory setups.
- Premium Borosilicate Glass (GG-17): Manufactured from high-quality GG-17 borosilicate glass, providing excellent thermal shock resistance and chemical durability for heating and boiling applications.
- Conical Body Design: Classic Erlenmeyer shape with a flat, stable base and tapered body, ideal for mixing, swirling, and minimizing spillage.
- Approximate Graduations: Clear volume markings (e.g., 100–250 ml) labeled “APPROX” for quick, rough volume estimation.
- Write-On Patch: Frosted labeling area for easy sample identification and marking.
- Narrow Neck: Reduces evaporation loss and splashing during mixing or heating; compatible with stoppers and cotton plugs.
- Heat-Resistant: Suitable for direct heating, boiling, and autoclaving in routine laboratory procedures.
Applications：
- General Liquid Handling: Used for holding, storing, and roughly measuring liquid samples and reagents.
- Solution Mixing & Preparation: Conical shape facilitates efficient swirling and mixing of solutions.
- Heating & Boiling: Designed to withstand heating and boiling of solutions on hotplates or over burners.
- Cultivation & Microbiology: Suitable for cell culture, microbial culture, and media preparation.
- Titration & Chemical Analysis: Commonly used as a reaction vessel in titration and general analytical procedures.
- Educational & Research Labs: A versatile staple in academic, industrial, and quality-control laboratories.
