12 best pyrex funnels

Pyrex funnels are laboratory glassware used for various scientific and industrial purposes, primarily in chemistry and biology. They are manufactured by Pyrex, a well-known brand for borosilicate glassware. Here's what you need to know about Pyrex funnels:

Material: Pyrex funnels are made from borosilicate glass, a type of glass known for its high resistance to thermal shock, chemical corrosion, and mechanical stress. This makes them suitable for a wide range of laboratory applications.
Design: Pyrex funnels typically have a conical or cylindrical shape with a stem at the bottom. The stem allows for controlled pouring of liquids into containers or other apparatus.
Wide Range of Sizes: Pyrex offers funnels in various sizes, from small funnels suitable for micro-scale experiments to larger funnels for industrial or bulk processes. The choice of size depends on the specific application.
Chemical Resistance: Borosilicate glass, used in Pyrex funnels, is highly resistant to chemical reactions, making these funnels suitable for working with a wide range of chemicals and reagents.
Heat Resistance: Pyrex funnels can withstand high temperatures, making them suitable for both hot and cold applications. They can be used for filtering hot solutions or for transferring substances between containers under various temperature conditions.
Laboratory Filtration: One common use of Pyrex funnels is in laboratory filtration processes. They are often paired with filter papers or membranes to separate solids from liquids, such as in gravimetric analysis or sample preparation.
Separatory Funnel: In chemistry, separatory funnels, also known as separating funnels, are used for liquid-liquid extractions. These specialized funnels have a stopcock or Teflon® valve at the bottom to control the separation of immiscible liquids.
Versatility: Pyrex funnels are versatile tools used for a wide range of tasks, including transferring liquids, decanting solutions, and performing qualitative and quantitative analyses.
Easy to Clean: Borosilicate glass is relatively easy to clean and sterilize, making it suitable for laboratory work where cleanliness and contamination control are essential.
Durability: Pyrex glassware is known for its durability and longevity. With proper care and handling, Pyrex funnels can last a long time in laboratory settings.
Safety: When working with Pyrex funnels, users should always follow proper safety procedures, wear appropriate personal protective equipment, and handle chemicals and glassware with care to prevent accidents.

In summary, Pyrex funnels are laboratory glassware made from borosilicate glass, known for its chemical and thermal resistance.These funnels are widely used in scientific and industrial settings for various applications, including filtration, liquid-liquid extraction, and general liquid handling. Their durability and versatility make them essential tools in laboratories and industrial processes.
