1. Reagent Bottles

    • 50ml, 100ml, 250ml, 500ml, 1000ml reagent bottles: Commonly used for storing various reagents, especially chemicals.
    • 5ml, 10ml, 20ml, 30ml, 40ml, 60ml, 125ml short-neck bottles: Short-neck bottles with a larger opening for easy handling and convenient filling.
    • 25ml, 50ml, 100ml conical bottles: Conical-shaped at the bottom, suitable for storing small quantities of samples or preparing samples.
    • 1000ml amber glass bottle: Typically used for storing sensitive reagents to avoid exposure to light.
  2. Pipetting Bottles

    • 1ml, 2ml, 5ml, 10ml, 20ml, 25ml, 50ml, 100ml pipetting bottles: Used for accurately aspirating and dispensing liquids, commonly found in chemical and biological laboratories.
    • 2ml, 5ml, 10ml, 20ml, 25ml, 50ml, 100ml funnel-top pipetting bottles: Designed with a reasonable funnel top for easy operation, enabling precise and rapid liquid distribution while controlling bubbles.
  3. Burettes

    • 1ml, 2ml, 5ml, 10ml, 20ml automatic burettes: Automatic burettes are typically used for acid-base titrations, redox titrations, and other analytical chemistry operations.
    • 1ml, 2ml, 5ml, 10ml manual burettes: Manual burettes, compared to automatic ones, are more cost-effective and commonly used for small-scale operations.
  4. Beverage Bottles

    • 250ml, 500ml, 750ml, 1000ml bottled beverage bottles: Used for packaging beverages and juices, often made of glass for easy cleaning and recycling.

Methods for correctly selecting the size of glass bottles:

  1. Choose the size of the bottle based on the required liquid volume, minimizing the number of unused round-bottom glass bottles.
  2. Use high-quality glass bottles. For routine experiments, regular reagent bottles and pipetting bottles can be used.
  3. Ensure an adequately large volume when selecting bottle capacity, considering the retention of a certain sample volume for other operations.

In conclusion, correctly choosing the size of glass bottles in the laboratory can not only facilitate experimental operations but also enhance overall efficiency.
