Very few containers were made specifically for experimental purposes prior to the early 1800s, and even then only for rich scientists such as the chemist Antoine Lavoisier (1743-94).
Some of Lavoisier's experimental glass vessels could loosely be described as test tubes.
The earliest recorded use of the expression 'Test-Tube', is from1846.
