To maintain constant good measurement results, a regular review of the accuracy of the spectrophotometer is required. With the use of certified reference materials from Hellma Analytics, you make sure that your equipment qualifications meet the requirements of the pharmacopoeias and fulfill your internal quality requirements, at the same time you reach the international comparability of your measurement results. The certified reference materials (calibration standards) of the DIN EN ISO 17025 accredited Hellma Analytics calibration laboratory are traceable to the primary standards of NIST (National Institute of Standards and Technology) and meet the requirements of the major pharmacopoeias (e.g. EP, DAB, USP).Your benefits: High quality of the measurement resultsInternational comparability of measurement resultsMeeting the requirements of the major pharmacopoeias (EP, DAB, USP)Results traceable to NIST primary standards30 years warranty on the reference materialsScope of delivery: Certified reference materials (Calibration Standards) in quality storage boxDAkkS Calibration Certificate (DIN 17025)Handling guidelinesCheck for stray lightHazardous Substance DataGHSSignal wordGefahrH-SatzH225, H304, H315, H319, H336, H361fd, H373, H411P-SatzP210, P261, P273, P281, P301+P310, P305+P351+P338SDSLink

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.Hazardous Substance DataGHSSignal wordAchtungH-SatzH290, H315, H319, H335P-SatzP234, P261, P312, P332+P313, P403+P233, P405UNNR3266SDSLink
