Titriplex® IV Lösung c (DCTA Na₂) = 0,1 mol/l, Titripur® für die Metalltitration, Supelco®
Lieferant: Merck
Synonyms:
CDTA Na2
M-Clarity™ Qualitätsstufe = MQ100
Note: The titer is a correction factor to correct for variations of the volumetric solution, the titration equipment, the temperature and other laboratory conditions. For correct titration results it is recommended to determine a titer with the laboratory specific equipment and under laboratory specific conditions directly after opening a new bottle and at regular time intervals.
Merck have introduced into the range of Titripur® Titrants some packs with additional technology - Supelco® SmartTitrants that use an RFID tag to provide a seamless data transfer between the smart titrator and the RFID tag on the label of the bottle of titrant. It will ensure that all information needed for method execution, result calculation and documentation is transferred to the titrator equipped with this technology. MettlerToledo Compact and Excellence titrators include this technology. Please see ordering table below for packs with RFID tag.
