ABSTRACT:
A reaction tube includes a resealable cap containing a lens. The body of the tube is translucent to admit spectrographic analysis light to pass through an internal reactant and to be collected by the lens eliminating the need to open the tube and expose the reactants to contamination from atmospheric agents during spectrographic analysis. The material of the tube is selected to permit necessary heating and centrifuging needed in DNA/RNA/protein reactions synthesis applications and to corral the reactants along a predetermined optical axis.
