Difference between laboratory and analytical reagent?

Analytical Reagents Are Useful In Sophisticated Analytical Instruments And Research Work Where High Purity Is Essential While Lab Reagents Are Useful To Carry Out Lab Analysis. ------ There used to be four grades of chemical: food grade, technical grade, lab grade and analytical grade. Food grade was safe and pure for use in foods, technical was for manufacturing nonfood items, lab grade was for lab research and analytical grade was as pure as they could possibly make. Not all chemicals could achieve all four grades; there was no food-grade arsenic or strontium-90 for reasons obvious. And some chemicals are the same in all four grades - borax, a mild base called sodium metaborate, is as pure in the "20 Mule Team" variety at the store as it is in reagent grade. Now there are dozens of grades. Google grades of reagents and the first hit is a very large page listing them all.

What are the advantages of pyrex glass?

Are you talking about Kitchen grade Pyrex (Tempered Soda Lime Glass) or Lab grade Pyrex (borosilicate glass)?Lab grade contains more metals such as boron, sodium, and aluminum making lab grade glassware better conductors of heat.Kitchen glassware do not conduct heat as well which prevents burning the bottom of whatever your baking.Both are less likely to break than other glass types.Exaxol Chemical Corporationhttp://www.exaxol.com

How would you purify NaCl bought from grocery to lab grade?

Table salt is already a refined salt, being 99% sodium chloride (NaCl). It usually contains substances (for the other 1%) that make it free-flowing (anti-caking agents) such as sodium silicoaluminate or magnesium carbonate. As both magnesium carbonate and sodium silicoaluminate are mostly insoluble in water, it could be possible to dissolve the sodium chloride and filter the insoluble particles. However, the particles will likely be very small and you may benefit more from using a chelating agent to pull the magnesium carbonate or sodium silicoaluminate out of solution before filtering. Both magnesium carbonate and sodium silicoaluminate are generally inert, however, and you may simply find it easier to simply use table salt, depending on he experiments you plan to carry out with the salt.
