Sodium phosphate dibasic heptahydrate is a reagent with very high buffering capacity widely used in molecular biology, biochemistry and chromatography. Sodium phosphate dibasic is highly hygroscopic and water soluble. Useful in conjunction with Sodium Phosphate, Monobasic (sc-202342, sc-215883 or sc-251042) in the preparation of biological buffers. Used in many applications including the purification of antibodies.
Additional forms available:
Sodium Phosphate, Dibasic (sc-203277)
Sodium phosphate dibasic dihydrate(sc-236917)
Sodium phosphate dibasic dodecahydrate (sc-236918)
Sodium phosphate dibasic solution (sc-301828)

If you are making a buffering solution, could the anhydrous form be used and if so what would be the calculation to determine the amount compared to the heptahydrate?

Asked by: Phil10
The anhydrous form can be used as a component in the preparation of phosphate based buffers, but we do not have the amount you would need.

Rated 4 out of 5 by from Satisfied Clean label with simple and direct information. One thing that I really thought they missed was the molecular formula. The label is clean, but contains the "written name" of the chemical only, without the molecular formula. All procedures do not use the written name, but rather the molecular formula. So, it would be great if both written name and molecular formula were there!
