Intro
A test tube is laboratory glassware used for sampling and testing chemical reactions. The test tubes were developed by a renowned British Physicist and Chemist - “Michael Faraday” (1791-1867).
Test tubes are also known as boiling tubes. These are slender containers with a U-shaped bottom and an open top. They can hold small amounts of liquids and are generally used in scientific experiments.

Types of Test Tubes
- Reusable Test Tubes - These types of test tubes are made up of superfine quality Borosilicate Glass 3.3. These tubes can be used more than once after sterilization. It further has 2 types: Glass Tubes and Culture Tubes.
- o Glass Tubes - These are normally used in labs for heating, boiling, and experimentation.
- o Culture Tubes - These tubes are mostly used to store Cell Cultures in laboratories.
Reusable Test Tubes are sturdy and are more heat resistant because they are manufactured from Boro 3.3 Glass. These are used for high precision chemical reactions. They can be reused.
- Disposable Test Tubes - These test tubes are manufactured in two types of glass: Boro 5.1 and Boro 7.0. The Boro 5.1 test tube is manufactured in two types - Glass Tubes and Culture Tubes. Whereas, Boro 7.0 tubes are general Glass Tubes. The disposable test tubes are very economical and are disposed of after their use.
