Water pipettes are ubiquitous in laboratory settings, serving as essential tools for transferring precise volumes of liquids. These versatile instruments are used in a wide range of applications, from conducting delicate biological experiments to performing routine chemical analyses. Their simplicity, accuracy, and affordability make them indispensable for scientists and researchers worldwide.
Water pipettes, physical characteristics
Water pipettes, also known as Pasteur pipettes, are characterized by their elongated, slender design. They consist of a thin, flexible tube, typically made of glass or plastic, and a bulb-like reservoir at the top. The lower end of the tube is tapered to a fine tip, allowing for controlled dispensing of liquids.
Materials of construction
The primary materials used in the construction of water pipettes are glass and plastic. Glass pipettes offer superior transparency, enabling clear visualization of the liquid being transferred. They are also chemically inert, making them suitable for use with a variety of solvents and reagents. However, glass pipettes are more fragile and prone to breakage compared to their plastic counterparts.
Plastic pipettes, on the other hand, are more durable and less susceptible to breakage. They are also lightweight and disposable, making them convenient for single-use applications. However, plastic pipettes may not be compatible with certain solvents or extreme temperatures.
Common uses
Water pipettes find extensive applications in various scientific disciplines, including:
- Biology: Are used for transferring small volumes of liquids in tasks such as preparing cell cultures, adding reagents to experiments, and sampling biological specimens.
- Chemistry: In chemistry labs, are employed for accurate dispensing of liquids during titrations, solvent extractions, and synthesis reactions.
- Medical diagnostics: Play a crucial role in medical diagnostics, enabling precise transfer of blood, urine, and other biological samples for analysis.
