Borosilicate Conical Flask

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.

In environmental research, conical flasks are used for sample collection, preparation, and analysis. They are commonly employed in water quality testing, soil analysis, and air pollution monitoring. The flasks' ability to withstand extreme temperature changes and chemical attack makes them suitable for collecting and storing samples from various environments.

Moreover, the wide base of the flasks allows for efficient mixing and filtering of samples, enabling researchers to obtain representative and accurate results. The transparency of borosilicate glass also allows for visual inspection of the samples, aiding in the identification of pollutants and contaminants.

Pharmaceutical Production

In the pharmaceutical industry, borosilicate conical flasks are used for preparing sterile solutions and vaccines. For instance, a pharmaceutical company may use these flasks to culture cells and harvest the desired proteins or antigens for vaccine production. The flasks' ability to withstand sterilization processes and maintain sterile conditions ensures the safety and efficacy of the vaccines.

Similarly, when producing sterile solutions, such as saline solutions or intravenous fluids, the bottle can be used to mix and dilute ingredients.The flasks' chemical resistance ensures that the solutions remain uncontaminated during production, while their clarity allows for easy visualization and measurement of the contents.

Biotechnology Research

In biotechnology research, it is used to culture cells and microorganisms such as bacteria and fungi.For instance, a biotechnology company may use these flasks to culture cells for the production of biopharmaceuticals, such as insulin or monoclonal antibodies. The flasks' smooth surfaces and narrow necks reduce the risk of contamination, while their wide bases provide sufficient surface area for cell growth.

Similarly, in the field of synthetic biology, the bottle can be used to culture engineered cells and organisms.The flasks' ability to withstand extreme conditions and maintain sterile conditions ensures the success of these experiments and the production of the desired products.

Analytical Chemistry Experiments

In analytical chemistry experiments, borosilicate conical flasks are used for sample preparation and analysis. For instance, a researcher may use these flasks to mix and dilute samples before they are analyzed using chromatography or spectrophotometry. The flasks' clarity allows for easy visualization of the samples, ensuring accurate and precise measurements.

Similarly, in electrophoresis experiments, borosilicate conical flasks are used for holding the electrophoresis gel and buffer solutions. The flasks' chemical resistance ensures that the gel and buffer solutions remain uncontaminated during the experiment, ensuring accurate and reproducible results.

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.

Performance

High temperature resistance:

Borosilicate glass has a high softening point, so that the borosilicate conical bottle can withstand high temperatures of up to 400~500 degrees Celsius. This characteristic makes borosilicate conical bottles widely used in high temperature experiments.

In contrast, conical bottles made of ordinary glass withstand lower temperatures, usually between 200 and 300 degrees Celsius. Beyond this temperature range, ordinary glass may crack or deform.

Chemical corrosion resistance:

Borosilicate glass has excellent chemical corrosion resistance and can resist the erosion of a variety of acid, alkali and salt solutions. This characteristic makes the borosilicate conical bottle have a long service life in chemical experiments.

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.
