Product H-3300 is supplied as a highly concentrated (100x) salt solution. It is recommended to be stored in the fridge. In some cases, over time with cold storage, some salts may come out of solution and appear as particulate or precipitated material. Our recommendation is to gently warm the bottle in a warm water bath to re-dissolve the precipitate. Usually 30 min at 35 °C would be sufficient. Once re-dissolved, an aliquot can be drawn from this solution and diluted according to the instructions. Re-dissolving the precipitate maintains the desired pH and salt concentration for optimal performance.
The stock solution of H-3300 is supplied as 1M citrate. Once diluted according to the instructions, the working concentration would be 0.01 M citrate. It is essentially a saturated concentrated salt solution.
