Laboratory test tube use

The glass tube and laboratory equipment must fit their intended use. The glass test tube is very often a mini-reactor, where a chemical reaction takes place. A glass tube must therefore withstand very diverse thermal conditions (high and low temperatures), adapt to various devices or supports (centrifuges, ovens, supports …), and have a flawless chemical compatibility with the usual lab reagents (mineral acids, mineral bases, organic solvents, harsh chemicals, etc.), most of which are extremely corrosive. Renes Glastechniek also offers borosilicate or soda lime glass tubes to fully meet the expectations of laboratory professionals.
