who intented the first glass test tube?

Answer 1

Jons Jacob Berzelius (1779-1848), a Swedish chemist, was known as the designer of the Berzelius form of beaker which is still used in labs today.

Test tubes, also known as culture tubes, are very much older than the 1800's. Wood cut pictures of test tubes and retorts go back to the days of alchemy.

Look at the item marked "Z" in the woodcut from 1606 in the second reference.

I am afraid that the inventor of the test tube is unknown and long forgotten.

Answer 2

Dip a standard glass cutter in vegetable oil, lay the test tube on a flat surface, press the glass cutter against the tube and spin the tube, That way you get a more precise cut that will be at 90 degree angle to the side of the tube unless it has a lip at the opening. The oil allows the cutter to cut with out chipping the glass and will help in preventing cracking when you break the excess tubing away

Answer 3

Jöns Jakob Berzelius. He was a towering figure in chemistry during the early 1800's- maybe second to Lavoisier, he can be called "the father of chemistry". He introduced the system of element symbols we use today and did some of the most important experiments of his time. To aid his research, he invented a number of laboratory items still used today- including the "test tube".
