A 100ml borosilicate glass measuring cylinder is an essential piece of equipment in any laboratory that deals with liquid measurements. It is designed to be accurate, reliable, and durable, allowing scientists to obtain precise measurements of liquid volumes. Here are some of the key features of a 100ml borosilicate glass measuring cylinder:

1. Material: The cylinder is made of high-quality, heat-resistant borosilicate glass that is resistant to thermal shock and chemical corrosion. This makes it ideal for use in a wide range of laboratory settings.
2. Graduations: The cylinder has clear, easy-to-read graduations marked on the side of the cylinder in increments of 1 ml, allowing for accurate measurement of liquid volumes. The graduations are etched into the glass, which makes them permanent and resistant to wear.
3. Tolerance: The cylinder has a tolerance of +/- 1 ml, meaning that measurements taken with the cylinder will be accurate to within 1 ml.
4. Dimensions: The typical dimensions of a 100 ml measuring cylinder are approximately 340 mm in height, 36 mm in diameter, and 2.0 mm in wall thickness.
5. Temperature range: The cylinder can typically withstand temperatures ranging from -50°C to 550°C without cracking or shattering.
6. Sterilization: The cylinder can be sterilized by autoclaving or by using chemical sterilization methods.
7. Cleaning: The cylinder can be cleaned using a wide range of cleaning agents, including water, soap, and alcohol.
8. Stability: The wide base of the cylinder provides stability, making it less likely to tip over when measuring liquids.
9. Durability: The borosilicate glass construction of the cylinder makes it resistant to breakage and thermal shock, ensuring that it will last for a long time with proper care.
10. Capacity: The 100ml capacity of the cylinder is sufficient for measuring larger volumes of liquid accurately.
11. Versatility: The 100ml measuring cylinder can be used for a wide range of applications, including measuring the volume of liquids, preparing solutions, and conducting experiments.

In addition to these features, some 100ml measuring cylinders may have additional features such as a pouring spout to facilitate the transfer of liquids and a hexagonal base to prevent rolling.

In conclusion, a 100ml borosilicate glass measuring cylinder is an essential tool in many laboratory settings. Its accuracy, durability, and ease of use make it an indispensable tool for scientists and researchers who require precise measurements of liquid volumes.
