Cleaning: HELLMANEX® III is an alkaline liquid concentrate used for the highly effective cleaning of glass or silica cells and other sensitive optical components. Laboratory equipment made of glass; quartz; sapphire and porcelain can also be cleaned using the solution. Characteristics: Hellmanex® III significantly reduces the surface tension of water. The removal of dirt particles is also assured by the good wetting action of a Hellmanex® III aqueous solution; whilst its high emulsifying and dispersing capabilities prevent the re-deposition of the loosened particles. Special surface-active substances facilitate the residue-free rinsing of the optical components once they have been cleaned. Cleaning and Dilution: The optimal dilution depends on several factors; such as the hardness of the water; the degree and type of contamination; the temperature; etc. The use of demineralised water improves the cleaning characteristics. Available in 1.3kg PE-bottle. The following treatments have been proven at a concentration (vol%) 0.5 to 2 in practice.
