1 Glass Test Tube

A glass test tube is a cylindrical vessel commonly used in laboratories for various scientific experiments and analyses. Typically made of borosilicate glass, test tubes come in different sizes, but a standard size is about 15 cm in length and 1.5 cm in diameter. They feature an open top and a rounded bottom, facilitating easy mixing and pouring of liquids or substances.

Test tubes are versatile tools in scientific research, allowing scientists to conduct a wide range of experiments such as mixing chemicals, heating substances, or observing reactions. They can be easily labeled for organization and identification purposes, and their transparency enables easy observation of reactions or changes in substances.

Due to their durability and inert nature, glass test tubes can withstand a variety of chemical reactions and can be reused after proper cleaning. Their simple yet effective design has made them a staple in laboratories across various scientific disciplines, from chemistry to biology and beyond.
