Product Introduction:
The graduated cylinder is a tall, cylindrical container with a spout on one side of the top for easy pouring. The bottom has a wide base to maintain stability. The walls of the cylinder are marked with graduations from bottom to top. When reading the measurement, the experimenter should ensure that their line of sight is level with the lowest point of the liquid's meniscus.

Precautions
- 1 When pouring liquid into a graduated cylinder, tilt the cylinder slightly and keep the mouth of the bottle close to the cylinder's opening. When the amount to be added is slightly less than the required volume, switch to a dropper to add the liquid until the desired amount is reached.
- 2 After injecting the liquid, wait 1 - 2 minutes for the liquid adhering to the inner wall to flow down, and then read the scale value. Otherwise, the measured value will be underestimated.
- 3 Do not dilute or prepare solutions in a graduated cylinder; do not heat the graduated cylinder.
- 4 Do not carry out chemical reactions in a graduated cylinder: it may damage the cylinder and sometimes even cause danger.
- 5 Do not leave the graduated cylinder with chemicals for long periods to avoid contamination by dust and evaporation of water from the solution.
- 6 Do not use scouring powder to clean to avoid scratching the markings.
Frequently Asked Questions (FAQ)
Q1: What material are these measuring cylinders made of?
A: They are made of high-quality BORO3.3 high borosilicate glass, which is highly resistant to thermal shock, high temperatures, and chemical corrosion.
Q2: What is the correct way to read measurements on a graduated cylinder?
A: Keep your line of sight completely level with the lowest point of the liquid's meniscus. Ensure the cylinder is placed on a flat, stable surface when reading.
Q3: Can I heat solutions directly inside the glass measuring cylinder?
A: No. Measuring cylinders are calibrated instruments meant only for volume measurement. They should never be heated, used to prepare solutions, or used for active chemical reactions.
Q4: What types of bases are available for your glass cylinders?
A: We offer a variety of options including stable round bases, hexagon bases, cylinders with glass stoppers, and cylinders with plastic hexagon bases featuring a guard ring.
Q5: How should the measuring cylinders be cleaned without damaging the markings?
A: Wash them gently with mild laboratory detergents. Never use scouring powder or abrasive brushes, as they can scratch the glass surface and wear away the printed scale markings.
