Glass pipettes are slender tubes made of glass, designed for transferring small amounts of liquid. They typically have a tapered end, allowing for precise dispensing. Commonly used in laboratories, they are essential for tasks like measuring reagents or transferring samples without contamination. These pipettes can come in various sizes and may be graduated, meaning they have markings to indicate volume. Unlike plastic pipettes, glass pipettes are reusable and can be sterilized, making them a more sustainable option in scientific settings. They are often used alongside other laboratory tools, such as test tubes and micropipettes.
