Sodium Sulfite, 99% min, Anhydrous, 1 lb.

used to make some other stuff and worked well for the mixture.

Awesome

I tried ordering this from Spectrum Chemicals and Sigma Aldrich. I needed this for a product I'm developing. These companies refused to sell it to me, even though I work for an established company. I was able to get this product, at comparable quality and a much better price without having to jump through the hoops of those other clowns.

Can get much more for less.

Says what is does and it does what it says. Great product and arrived very fast.

Used to calibrate dissolved oxygen analyzer, works as intended. Happy with product.
