<strong>Karl</strong> <strong>Fischer</strong> Reagent SS-Z Series (Pyridine/Chlor<strong>of</strong>orm-Free Type)<br />
Mitsubishi's SS-Z range <strong>of</strong> titration products is free <strong>of</strong> both pyridine and<br />
chlor<strong>of</strong>orm.<br />
These products are kind to both people and the environment.<br />
<strong>Karl</strong> <strong>Fischer</strong> Reagent SS-Z is a volumetric titration reagent that contains<br />
neither chlor<strong>of</strong>orm nor methyl cellosolve. It is also free <strong>of</strong> pyridine so there is<br />
almost no odor.<br />
A low-toxicity solvent system has been used to develop a product that is<br />
kind to both people and the environment while providing the same<br />
performance as earlier products.<br />
These products can be used with existing moisture content measuring<br />
systems. Combine them with the dehydrated solvent that is appropriate for<br />
the sample.<br />
