What property does a large orifice in a serological pipette offer?

A large orifice in a serological pipette provides the advantage of faster drainage of viscous solutions. This is particularly beneficial when working with thicker liquids that may not flow easily through a smaller opening. The wider diameter allows for less resistance and facilitates smoother and quicker expulsion of these solutions, making the process more efficient.

In laboratory settings, speed can be a critical factor, especially during high-throughput testing or experiments requiring rapid transfers. Thus, when dealing with viscous substances, the design of the pipette is crucial for maintaining efficiency and effectiveness in handling samples.
