Is that such a good idea?

Before mechanical and automatic pipettes, and apparently before these,
















folk in the lab would use their mouths to suck up whatever awful thing they were working with.

A survey of 57 labs in 1915 found 47 infections associated with workplace practices, of which 40% were attributed to swallowing a corrosive or toxic substance or infectious lab specimen. A longitudinal study of 921 workplace laboratory infections between 1893 and 1950 found 17% were due to “oral aspiration through pipettes or to splashes of culture fluids into the mouth.”(link)
