EISCO Graduated Cylinder, 250mL – Class B Tolerance – Octagonal Base – Polypropylene Plastic – Industrial Quality, Autoclavable

Description

Product Overview

The EISCO 250 mL graduated cylinder is engineered for precision, durability, and versatility in a wide range of scientific and educational settings. Constructed from high‑grade polypropylene, the cylinder resists chemical attack, tolerates high temperatures, and endures repeated autoclave cycles without warping or loss of clarity. Its translucent body allows users to monitor liquid levels at a glance, while the octagonal base ensures the instrument remains firmly seated on work surfaces, reducing the risk of tipping during critical measurements. The cylinder features raised 2 mL graduation lines that are clearly marked every 20 mL, providing both fine resolution for small volume work and easy readability for larger volumes. The overall dimensions—approximately 14 × 2 × 3 inches and a weight of 3.2 ounces—make it compact enough for bench storage yet large enough to handle typical laboratory tasks. Certified with Class B tolerance, the device meets industry standards for accuracy, making it a reliable choice for quantitative analysis, solution preparation, and quality control procedures.

Usage

Designed for professional laboratories, the cylinder excels in environments where accuracy and repeatability are paramount. Researchers use it for titration, dilution, and sample preparation in chemistry, biology, and environmental testing labs. In educational settings, the clear markings and sturdy construction make it an excellent teaching tool for high‑school and university science courses, allowing students to develop hands‑on experience with volumetric measurement. The autoclavable nature of the polypropylene material simplifies decontamination after handling hazardous or bio‑contaminated substances, ensuring compliance with safety protocols. Additionally, the cylinder is suitable for home science enthusiasts who conduct hobbyist experiments, such as small‑scale chemical syntheses, aquarium water testing, or DIY calibration projects. Its chemical‑resistant properties mean it can safely contain acids, bases, solvents, and other reagents commonly encountered in these applications.

FAQ

Can this cylinder be used with aggressive chemicals?

Yes. The high‑quality polypropylene material is resistant to most acids, bases, and organic solvents, making it suitable for a wide range of chemical applications.

Is the cylinder safe for repeated autoclave cycles?

Absolutely. Polypropylene tolerates the high temperatures and pressures of standard autoclave cycles without deformation, ensuring the graduations remain accurate after many sterilizations.

What does Class B tolerance mean for my measurements?

Class B tolerance indicates the cylinder meets a specific accuracy range defined by industry standards, providing reliable volume measurements suitable for most laboratory and educational purposes.

How do I clean the cylinder after use?

Rinse the cylinder with appropriate solvents to remove residues, then place it in an autoclave for a standard cycle. For non‑sterile cleaning, warm soapy water followed by a thorough rinse is sufficient.

Is this cylinder appropriate for classroom demonstrations?

Yes. Its clear markings, sturdy construction, and safety‑focused design make it an ideal tool for teaching volumetric techniques in high‑school and university labs.
