Jhon, as a child, was very neurotic. it caused certain chemical out bursts in his nervous system, but, dispite his difference he had a love. a joy. a reason to keep going; that was his love for inventing. he invented the test tubes when he was with his father. his father wanted something to put his chemicals in to hold carefully and neatly, and, being an inventor, Jhon's mind clicked, snapping his fingers in a smooth motion, and swallowing the barley sugar he been sucking whole, he ran inside, and sketched the tube. it was a cylinder with an opening at the top. he first created it with rubber, but then, thinking of how people would want to see into it, he made it of a palstic/glass material. Old Jhon Flamsteed, the invented the test tubes.
To clean inside test-tubes properly. If it didn't exist it would have to be invented.
Bigger, fatter test tubes are usually called boiling tubes.
They are called: - Test tubes - Cultural tubes - Sample tubes
Different laboratories may use different color codes for test tubes depending on their specific protocols. However, a common color coding for test tubes used in centrifuges is as follows: red for serum tubes, lavender for EDTA tubes, green for heparin tubes, and blue for citrate tubes.
it can test experiments if it is successful or failes
This answer is disputed, but many people think they were invented by Jhon Flamsteed, while others argue that some of the tools used by Antoine Lavoisier could be considered to be test tubes. The first recorded use of the term was in 1846, although they may have been in use in different forms before then.
Test tubes was invented by Jhon Flamesteed

The test tube clamp was invented to securely hold test tubes in place, preventing them from falling or spilling chemicals during experiments. It allows for safe handling and manipulation of test tubes, especially when they need to be heated or stirred.
If the test tubes need to be sterile, you would have to autoclave them.
A group of test tubes are called samples.
85% of 140 test tubes= 85% * 140= 0.85 * 140= 119 test tubes
Bigger, fatter test tubes are usually called boiling tubes.
The amount of gas in test tubes can differ based on factors such as the volume of the test tubes, the pressure inside the test tubes, and the temperature of the gas. Different test tubes may contain different amounts of gas depending on these variables.
