Experimental Design Tips
- For density or concentration work, pair the 25 mL cylinder with an analytical balance to record mass before and after filling.
- When blending liquids (perfumes, oils, nutrient solutions), note volume ratios to replicate formulations consistently.
- Photographically document meniscus readings under consistent lighting for record-keeping or teaching purposes.
| Learning Outcome / Key Feature |
Description |
| Understand Precision Measurement |
Learn how to read meniscus levels accurately and estimate measurement uncertainty. |
| Minimize Sample Waste |
Use small volumes to reduce reagent use in repeated trials or educational labs. |
| Temperature and Chemical Stability |
Borosilicate glass tolerates heat and most lab solvents without distortion or staining. |
| Versatile Educational and Practical Use |
Applies to classroom demonstrations, fragrance formulation, and nutrient solution testing. |
Best Practices for Use
- Read the Meniscus at Eye Level: Always align your sightline with the bottom of the liquid curve.
- Rinse Between Samples: Prevent cross-contamination between essential oil, nutrient, or perfume batches.
- Avoid Overfilling: Leave space for safe mixing or thermal expansion during warm reactions.
- Use a Stable Surface: Place the cylinder on a flat, vibration-free bench to ensure accuracy.
A 25 ml graduated cylinder can be read accurately to 0.25ml at full scale but for metered measurements, use a buret. Our 25ml graduated cylinders are made from borosilicate glass ("pyrex"); buy box sizes of 12 for a 30% discount.

There are roughly 25mm per inch & 25mL for fluid ounce.
