Transfusion bottles are typically made of either neutral glass or borosilicate glass due to their excellent chemical resistance and durability. Neutral glass is chemically stable and resistant to a wide range of substances, making it suitable for medical applications such as transfusion bottles. Borosilicate glass is known for its high thermal resistance and low coefficient of thermal expansion, which makes it ideal for use in environments where temperature changes are frequent. It also offers excellent chemical durability.

**_ While neutral glass is indeed used for transfusion bottles due to its chemical stability and resistance, it is not the only type of glass used. Therefore, considering only neutral glass is not completely accurate. Borosilicate glass is a preferred material for many medical applications due to its thermal resistance and durability. However, similar to neutral glass, it is not the sole material used for transfusion bottles. Soda glass, also known as soda-lime glass, is commonly used in the production of bottles and jars for food and beverages due to its lower cost. However, it is not suitable for medical applications like transfusion bottles because it lacks the chemical resistance and durability required. Transfusion bottles are made of both neutral glass and borosilicate glass due to their superior chemical resistance and durability, making them suitable for medical applications. Soda glass, on the other hand, does not meet the necessary standards for such use.
