Features include borosilicate 3.3 glass for high chemical resistance and durability, a 100 ml capacity, blue graduations for easy readability, and a hexagonal base for stability during handling. The model uses a 19/26 polypropylene stopper; while not a glass stopper, it provides a secure seal and reduces evaporation risk in short-term experiments. This cylinder balances accuracy with practical storage functionality for routine lab work.
Labasics 100 ml Graduated Cylinder With Stopper
Specifications: 100 ml capacity with 2 ml graduation intervals starting at 20 ml. Includes a 24/40 standard ground joint stopper for a precise, secure seal. Borosilicate glass offers excellent resistance to acids and alkalis, enabling durability and reuse across multiple experiments. Suitable for measuring liquids and short-term storage with minimized evaporation.
Labasics 250 ml Graduated Cylinder With 24/40 Stopper
Specifications: 250 ml capacity with 2 ml graduation intervals starting at 20 ml. Features a 24/40 standard ground joint stopper for precise sealing and secure storage. Borosilicate glass ensures good chemical resistance and durability for repeated laboratory use. This size is ideal for larger-volume measurements and routine sample handling in teaching or research labs.
EISCO 100 ml Graduated Cylinder Class B
Features: High-quality borosilicate glass, Class B ISO 4788 specification, and blue 1.0 ml graduation lines marked every 10 ml. Includes a 19/26 polypropylene stopper that can be swapped for different experiments. The cylinder combines reliability with compliant measurement standards, suitable for instructional environments and routine lab tasks that require consistent accuracy.
Karter Scientific Glass Graduated Cylinder Set
Includes 10 ml, 50 ml, and 100 ml graduated cylinders with rubber stoppers to fit. This set provides a range of volumes with a single metric scale for quick access during multi-step experiments. Suitable for teaching labs and preparatory work where multiple sizes are advantageous for different procedures and sample volumes.
Karter Scientific 100 ml Graduated Cylinder
Specifications: 100 ml capacity with 1 ml graduations from 10 ml to 100 ml, tolerance ±1 ml. Borosilicate glass provides chemical durability, and the single metric scale supports straightforward measurement in standard lab tasks. This option is well-suited for classrooms and laboratories that emphasize precision in finite volume increments.
DONLAB 25 ml Glass Graduated Cylinder
Features: 25 ml capacity with a ground glass stopper, made from Borosilicate 3.3 glass for improved chemical resistance. Compact size makes it suitable for small-volume experiments and sample preparation. The ground glass stopper enhances sealing integrity for short-term storage and precise handling of liquids in instructional and research settings.
Buying Guide: Key Considerations For Choosing A Graduated Cylinder With Stopper
- Volume range and graduation spacing: Select a size that matches your typical liquid volumes and the needed precision. Smaller cylinders with 1–2 ml graduations suit precise titrations, while larger volumes prioritize ease of measurement and reduced refills.
- Material and chemical compatibility: Borosilicate glass (3.3) offers strong chemical resistance and durability, suitable for acids and alkalis. Check for compatibility with your reagents to minimize etching or clouding over time.
- Stopper type and compatibility: Joins like 19/22 or 24/40 provide different sealing options. Ground glass stoppers generally offer tight seals but may require lubrication or careful handling; polypropylene stoppers offer chemical resistance and easy automation integration.
- Base design and stability: A hexagonal or round base with a wide footprint reduces tipping risk during transfers. Stability is important for accurate readings and safe handling of liquids.
- Readability and markings: Clear, contrasting graduations improve accuracy. Color-coded or blue graduations aid quick reading in busy lab settings.
- Optional sets vs. single units: Sets provide flexibility across volumes, which can be cost-effective for teaching labs and multi-step experiments.
- Maintenance and reuse: Durable borosilicate glass can withstand frequent washing and reuse, but ensure compatible cleaning processes to prevent residue and calibration drift.
- Storage and handling: Consider whether you need flat-stable bases for bench work or a compact form factor for storage in limited space.
For best results, match the cylinder’s capacity and stopper style to the intended workflow. If long-term storage is a priority, a robust stopper and glass with high chemical resistance will reduce evaporation and composition changes. For teaching labs and demonstrations, ease of reading, stability, and a broader selection of sizes can streamline instruction and reduce setup time.
In summary, the options above offer a range of capacities, stopper types, and materials designed to fit common laboratory tasks. Each product focuses on reliable measurement and secure sealing to support accurate liquid handling for American laboratories, classrooms, and research environments.
