Detergent Hellmanex® III

The highly effective alkaline cleaning concentrate Hellmanex III is ideal for use on glass and quartz glass cuvettes, sensitive optical parts and laboratory equipment made of glass, quartz, sapphire and porcelain. It effectively removes dirt and prevents loosened dirt particles from redepositing. After cleaning, the parts can be rinsed without leaving any residue, including UV/Vis active substances, being left on the optical substances. Steps for a clean cuvette Place the cuvettes in a bath of Hellmanex III diluted to 2 % with water. Clean flow-through cuvettes by pumping the cleaning solution through the cuvette. The cleaning process can be sped up by gently heating the solution. Agitate the cleaning solution to boost cleaning performance. After cleaning, thoroughly rinse the cuvettes using ultrapure water. Replace the contents of the cleaning bath at least three times during rinsing. Blow the cuvettes dry using clean air and leave them to dry out in a dust-free environment. Alternatively, rinse them with a highly volatile solvent, such as ethanol. Then allow the solvent to evaporate.
