About This Product
Test tubes hold small volumes of liquids and solids during school experiments. In chemistry classes they are used for reactions, for gentle heating over a flame, and for observing colour changes or precipitates. In biology they serve for simple tests such as food tests and enzyme demonstrations. Borosilicate glass is a common choice for lab glassware because it tolerates heating better than ordinary glass. A Test Tube Holder is used when a tube is warm. Schools, colleges and distributors in Mali, Barbados, Trinidad and Tobago, Brazil, Bosnia and Herzegovina and Mexico can source the Test Tubes from School Lab Equipment India.
