The Arco Measuring Cylinder 100 mL Class-A Hexagonal Base is a precision, high-quality glassware instrument designed for accurate volume measurement in laboratory, educational, industrial, and research settings. This Class-A cylinder delivers excellent reliability, meeting stringent tolerance standards, and the hexagonal base adds stability, safety, and ease of handling.
Key Features & Benefits
| Feature | What It Is | Benefit to You |
|---|---|---|
| Capacity: 100 mL | Holds up to 100 millilitres of liquid with clear graduations | Suitable for medium volume measurements—good balance between size and readability |
| Class-A Accuracy | Manufactured to internationally recognized precision standards (e.g. DIN/ISO/ASTM) | Low tolerance of error, more precise readings, suitable for analytical work |
| Hexagonal Base | Broad, six-sided base rather than round or narrow | Much more stable, less likely to roll or tip; safer, especially on uneven surfaces or crowded benches |
| Borosilicate Glass (Type 3.3 or similar) | High-quality, temperature & chemical-resistant glass | Can handle mild thermal stress; resists many chemicals (acids, bases) without reacting; long-lasting durability |
| Clear, Permanent Markings | Graduations etched or fired-on, easy to read | Helps in avoiding mistakes; visibility even with colored fluids; markings remain after washing or solvents |
Specifications (Typical / Expected)
- Material: Borosilicate glass (Type 3.3 or equivalent)
- Capacity: 100 mL
- Tolerance: ± 0.50 mL (or as per Class-A standard)
- Graduation subdivision: 1.0 mL increments
- Base: Hexagonal, wide for better stability
- Markings: Clear, white or blue (depending on model)
- Additional options: may include spout (for easy pouring), polypropylene stopper, or joint standard (if relevant)
Applications / Ideal Uses
- Analytical chemistry labs for preparing solutions with accurate volumes
- Educational labs (schools, colleges, universities) for teaching volumetric measurement
- Industrial quality control where precise liquid measurement is required
- Research and development laboratories
- Sample preparation in biotech, pharmaceutical, environmental, or chemical testing labs
How It Compares / Why Choose This
- Better Stability: The hexagonal base prevents rolling or accidental tipping, unlike round bases.
- Higher Accuracy: Class-A cylinders have tighter tolerances than Class-B ones, meaning less error.
- Durability: With borosilicate glass and permanent markings, this cylinder will last through regular lab use.
- Versatility: Works for a variety of liquids, and the size is convenient—bigger than say 50 mL for when more volume is needed, but not bulky like 250–500 mL versions.
Care & Usage Tips
- Always place it on a flat, stable surface when measuring
- Read the meniscus at eye level for accurate volume reading
- Wash gently using non-abrasive brushes and mild detergents
- Avoid sudden temperature changes (e.g., from cold water to flame) to prevent glass breakage
- Handle carefully, since glassware is fragile; inspect for cracks/chips before use
