How are transfer pipettes, also known as Beral pipettes, characterized?

Transfer pipettes, commonly known as Beral pipettes, are characterized by being made from a single piece of plastic. This design gives them a lightweight, flexible structure, making them suitable for transferring small volumes of liquids, often in informal laboratory settings or fieldwork. The design allows for easier handling and reduces the risk of breakage compared to traditional glass pipettes.

Their structure also enables them to be relatively low-cost and disposable, providing a hygienic option for single-use applications, which can be advantageous in minimizing contamination. This characteristic distinguishes them from other types of pipettes, such as glass ones, which are made from more fragile materials and may not be as convenient for one-time uses.
