Description

A Pasteur pipette with rubber teat is a laboratory tool used for transferring small volumes of liquids, usually less than 1 milliliter. The pipette consists of a thin, cylindrical glass tube with a rubber teat at one end. The rubber teat can be compressed and released to control the suction and release of the liquid.

The Pasteur pipette with rubber teat is commonly used in biology, microbiology, and biochemistry for various applications, such as the transfer of culture media, bacterial suspensions, or biochemical reagents. They are also used in medical diagnostics and food industry for sample preparation and analysis.

The use of Pasteur pipette with rubber teat requires careful handling and proper technique to prevent contamination or error. The pipette should be calibrated and standardized to ensure accuracy and precision. The rubber teat should be cleaned and sterilized regularly to prevent bacterial growth or degradation.

Pasteur pipettes with rubber teats are disposable and inexpensive, making them a convenient and efficient tool for small-volume transfers in laboratory settings. They are also environmentally friendly and can be recycled after use. However, their accuracy and precision may be limited compared to more advanced pipetting techniques, such as micropipettes or automated systems.
