Specifications
The Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Red Stripe 20024D 500, Pack boasts several key specifications:
- Capacity: 500mL. This is the maximum volume the cylinder can accurately measure.
- Graduation Range: 25-500mL. Measurements are reliable only within this range.
- Graduation Interval: 5mL. Each marking on the cylinder represents a 5mL increment.
- Tolerance: ±2.6mL. This indicates the acceptable margin of error for any measurement.
- Approximate Height: 375mm. Overall height makes it stable.
- Bumper Size: 7. Relates to the size/fit of the SAFE-GARD bumper.
- Material: Borosilicate Glass. This offers chemical resistance and thermal stability.
- Class B Accuracy: Meets ASTM E1272, Style 1, Class B standards for accuracy.
These specifications are crucial because they determine the cylinder’s suitability for specific tasks. A larger tolerance means the cylinder is less precise, making it unsuitable for applications requiring high accuracy, but acceptable for general measuring tasks where economy is important. The borosilicate glass ensures compatibility with a wide range of chemicals without fear of corrosion or contamination.
