Product Description:
o-Cresolphthalein Complexone is complexometric reagent derived from o-Cresolphthalein. It shows violet-red color in alkaline media and is a principle compound for the determination of hardness of water.Also used as Calcium Assay Kit as direct colorimetric assay based on the O-Cresolphtalein (OCPC) method without deproteinization of the sample. The calcium determination is based on the reaction of calcium with O-Cresolphthalein complexone in alkaline solution, which yields a violet colored complex. The intensity of the color formed is proportional to the calcium concentration in the sample. Absorbance of the Ca2+-O-Cresolphtalein complex is measured at 570nm. Wavelength range of sensitivity: 560 ~ 590nm.

In order to remove hydrogen in the aluminum liquid, the Silicon Nitride Ceramic hollow degassing rotor is used to feed nitrogen or argon, and the gas is dispersed by high-speed rotation,finally achieve the effect of neutralizing and discharging hydrogen.
ï?¬Compared with graphite rotor, Silicon Nitride Ceramic will not be oxidized under high temperature environment, so it will not pollute the aluminum liquid, and the service life is much longer;
ï?¬The property of high thermal shock resistance ensures that the degassing rotor will not break during frequent intermittent operation;
Because Silicon Nitride Ceramic is of high density and high strength, it assures that degassing rotor can be reliable and stable in high speed rotation.
