Description
Technical Parameters
The history of borosilicate glass dates back to the early 20th century when it was first developed to address the limitations of traditional soda-lime glass, which is prone to thermal stress and shattering.Borosilicate conical bottle is a kind of glass container commonly used in laboratory, made of borosilicate glass, with excellent heat resistance, chemical stability and physical strength, suitable for various chemical experiments and research.
In the realm of scientific research and experimentation, the borosilicate conical flask stands as a pivotal piece of laboratory equipment. Its design, made from the robust and versatile material of borosilicate glass, has rendered it indispensable across various scientific disciplines.
This article delves into the intricacies of the borosilicate glass, examining its composition, properties, applications, and the significant role it plays in facilitating accurate and reliable research outcomes.
Composition and Properties of Borosilicate Glass
Borosilicate glass, also known as zirconia silicate glass, is a type of glass with a high content of boron oxide and silica. This unique composition it several advantageous properties that make it ideal for laboratory use.
Firstly, borosilicate glass exhibits a low coefficient of thermal expansion. This means that it can withstand significant temperature changes without undergoing significant expansion or contraction, thereby minimizing the risk of cracking or breaking. This thermal stability is particularly crucial in laboratory settings where equipment is frequently subjected to rapid temperature fluctuations, such as during heating and cooling processes.
Secondly, borosilicate glass possesses excellent chemical resistance. It is highly resistant to attack by acids, bases, and other chemical agents, making it suitable for use with a wide range of substances. This chemical inertness ensures that the material does not react with the contents of the flask, thereby preserving the purity and integrity of the samples being analyzed.
Thirdly, borosilicate glass is highly transparent. This allows for clear visualization of the contents within the flask, enabling researchers to monitor reactions and changes in real-time. The clarity of the material also facilitates accurate measurement and observation, which is essential for precise experimental results. |

Specifications
Design and Features of the Conical Flask
The conical flask, also known as an Erlenmeyer flask, is characterized by its distinctive cone-shaped body and a narrow neck. This design serves several practical purposes that make it well-suited for a variety of laboratory applications.
The wide base of the conical flask provides stability, preventing it from tipping over or falling during use. This is particularly important when the flask is filled with liquid or subjected to agitation or stirring. The narrow neck, on the other hand, allows for easy pouring and handling of the contents without spillage.
Additionally, the cone-shaped body of the flask facilitates efficient mixing and stirring of its contents. The gradual tapering of the sides creates a vortex effect that helps to distribute reactants and catalysts evenly throughout the liquid, thereby promoting more uniform and consistent reactions.
The bottle is usually fitted with a stopper or lid to prevent evaporation and contamination of the contents.This feature is particularly useful when storing samples or conducting reactions over extended periods. The stopper also allows for the flask to be sealed tightly, enabling it to be transported or stored without the risk of leakage. |

How to dry after cleaning

Natural drying
Method: Put the cleaned conical bottle upside down in a dust-free place, such as a glass cabinet, and let it dry naturally.
Advantages: Simple and easy, no additional equipment is required.
Note: It is necessary to ensure that the environment is dry and hygienic, and avoid dust and bacterial contamination. At the same time, the natural drying time may be longer and is not suitable for conical bottles that are in urgent need of use.
Oven drying
Method: Put the cleaned conical bottle into the preheated oven and dry it for 23 hours at the appropriate temperature (such as about 70℃). It is also possible to set the oven temperature at 105120 ° C and keep it warm for about 1 hour.
Advantages: The conical bottle can be dried quickly and evenly.
Note: It is necessary to ensure that the oven temperature is not too high to avoid cracking the conical bottle. At the same time, in the drying process, it is necessary to keep the environment dry and sanitary, and avoid adverse effects of smoke and odor on the human body.


Air drying
Method: Put the cleaned conical bottle into a drying box with a fan and dry it by air flow and temperature.
Advantages: The conical bottle can be dried quickly, and the problem of excessive temperature can be avoided.
Note: It is necessary to ensure that the air flow in the drying box is uniform to avoid local overheating or uneven drying of the conical bottle.
Note summary
Before drying, the conical bottle must be thoroughly cleaned and its inside and outside surfaces wiped clean.
During the drying process, it is necessary to operate carefully to avoid excessive drying temperature or too long time, so as not to crack the conical bottle.
After drying, the conical bottle should be stored in a dry and ventilated place to avoid moisture or contamination again.

Thermal stability:
Borosilicate glass has a low coefficient of thermal expansion, which makes the borosilicate conical bottle can still maintain the stability and integrity of the structure at high temperatures. At the same time, it can also withstand large temperature changes and is not easy to break.
Light transmission performance:
The borosilicate glass has good light transmission performance, so that the internal reaction of the borosilicate conical bottle can be clearly observed in the experiment.
Mechanical strength:
The borosilicate conical bottle has high mechanical strength and can withstand certain pressure and impact. This characteristic makes it able to withstand various operations and treatments in the laboratory.
