hwo much total purity of sodiumhypocholorite in used in medical laboratories?
It could, though medical-grade oxygen is significantly more expensive than welding-grade oxygen so I'm not sure why you would want to do this.
6th grade
Nuclear grade resin has got higher capacity ,it produce high purity water,were as non nuclear grade resin produce purity water not high purity......
You need a prescription for a medical grade oxygen concentrator.That's one which produces Oxygen at a 90% concentration.
If you are referring to chemical purity by grade, I suggest you research the following terms: ACS Grade (American Chemical Society) - highest level of purity Reagent grade - Almost as stringent as ACS USP Grade - Equivalent to ACS for many drugs NF Grade (National Formulary) - Equivalent to ACS for many drugs Laboratory Grade Purified Grade Technical Grade
99.999%
The purity is different.
99,99999 % purity
It is a way of defining the standard of purity of a chemical compound
Copper with a purity of 99,99 %.
Technical grade chemicals are less pure than reagent grade chemicals, and are usually used in applications where there are no official standards for impurity levels.Commercial grade chemicals are prepared in volume for general industrial use. Purity levels vary but they're often comparable in purity to technical grade chemicals.
