A Borosilicate Measuring Cylinder with a capacity of 100 ml (milliliters) is a fundamental piece of laboratory glassware used for measuring and transferring precise volumes of liquids. Here’s an in-depth description of its features and applications:
 
  Key Features:
 
1.  Material :
   -  Borosilicate Glass : Made from borosilicate glass, which is renowned for its high thermal resistance, chemical durability, and transparency.
   - Ensures clear visibility of the liquid contents and allows for accurate reading of volume markings.
 
2.  Design :
   -  Shape : Typically cylindrical with a uniform diameter throughout its height.
   -  Capacity : Holds up to 100 ml of liquid, with clearly marked graduations on the glass surface for precise volume measurement.
   -  Base : Often includes a stable base to prevent tipping and ensure stability on laboratory surfaces.
 
3.  Graduations :
   -  Volume Markings : Graduations are engraved or printed on the glass, calibrated to indicate precise increments, usually in milliliters (ml).
   -  Accuracy : Designed to provide accurate volume measurements, crucial for scientific experiments and laboratory procedures.
 
4.  Pouring Lip :
   - Features a spout or pouring lip at the top to facilitate controlled pouring of liquids, minimizing spillage and ensuring accuracy in transfer.
 
5.  Usage :
   -  Volume Measurement : Essential in laboratories for measuring specific volumes of liquids with high precision.
   -  Mixing and Dilution : Facilitates the preparation of solutions by accurately measuring and combining liquids in controlled proportions.
   -  Dispensing : Enables precise dispensing of liquids into other containers or vessels without the need for additional measuring devices.
 
6.  Cleaning and Maintenance :
   - Requires regular cleaning using suitable laboratory cleaning agents to maintain cleanliness and accuracy.
   - Handle with care to avoid damage to the graduations and base, ensuring longevity and continued accuracy.
 
  Advantages:
 
-  Precision : Provides precise volume measurements due to clear and accurate graduations.
-  Durability : Resistant to chemical corrosion and thermal shock, ensuring reliability and longevity in laboratory environments.
-  Versatility : Suitable for a wide range of liquids used in scientific research, quality control, and educational experiments.
 
  Applications:
 
-  Laboratory Use : Essential in chemistry, biology, and physics laboratories for conducting experiments, preparing solutions, and accurate liquid measurement.
-  Industrial Applications : Used in pharmaceuticals, food processing, and environmental testing for precise liquid measurements and quality control.
-  Education : Valuable in educational institutions for teaching and demonstrating principles of volume measurement and liquid handling techniques.
 
  Limitations:
 
-  Fragility : While made from durable borosilicate glass, it requires careful handling to prevent breakage, especially at the base and along the graduations.
-  Cost : Initial investment may be higher compared to plastic alternatives, but offers superior durability and accuracy over time.
 
  Conclusion:
 
A 100 ml Borosilicate Measuring Cylinder is an essential tool in laboratory and industrial settings for accurately measuring and transferring liquid volumes. Its robust construction, clear graduations, and resistance to chemical and thermal stresses make it indispensable for precise scientific research, quality assurance, and educational purposes where accurate liquid measurements are crucial for reliable experimentation and analysis.
