AND AX33 Sodium tartrate dihydrate test samples. You get 12 packages containing 30 grams per package
Sodium tartrate dihydrate, Na2C4H4O6•2H2O is a unique chemical for testing the accuracy of measurement for any moisture analyzer to be sure it is operating properly. Many people test moisture balance accuracy by making a solution of 90 gram distilled water with 10 grams table salt, thus yielding 10% solids but for many people they want a more scientific test and sodium tartrate dihydrate is the answer for many.
The chemical starts as sodium tartrate to which two molecules of water are bonded making it a dihydrate. The chemical is stable at temperatures up to 150° C, and when heated at higher temperatures the water molecules are driven off. The chemical can be used as a primary standard for testing moisture analyzer. The theoretical moisture content of Sodium tartrate dihydrate is 15.66% by weight, . but the moisture content may change due to conditions of storage.
The moisture content of 15.0 to 16.0% is obtained by the method below.
After preheating the analyzer, the data can be obtained with approximately 5 g test sample (Sodium tartrate dihydrate) in standard mode (MID.), standard drying, 160°C
(Unit % is based on wet sample)
Sodium tartrate is contained in food (example : wine). If it may irritate the eyes and nose, wash with water.
The test sample can not be used repeatedly. Dispose of it as flammable matter. The material does not require special treatment for disposal. It can be disposed of as ordinary burnable waste.
AND Weighing moisture analyzers
MS-70 MX-50 and MF-50 so with two (2) test samples of sodium tartrate dihydrate when you purchase a new moisture analyze.
The AND ML-50 moisture balances does not come with any test samples of sodium tartrate dihydrate
and must be purchased as an optional accessory.
