Potassium dihydrogen phosphate at 6.8 g\/L and sodium hydroxide at 1.4 g\/L form the buffer system, with no sodium chloride and no nutrients in the formulation.\u003c\/p\u003e\n\u003cp\u003eControl organisms held within ±50% of the starting count after 45 minutes at 20–25 °C, the data-sheet criterion for a diluent. Suspending 8.2 g in 1 L of purified water, heating to dissolve and autoclaving at 121 °C for 15 minutes gives a clear, colorless buffer at pH 7.2 ± 0.1. It fits serial dilutions and sample suspensions for aerobic plate counts, yeast and mold counts, and sample preparation ahead of selective plating.\u003c\/p\u003e\n\u003c!-- \/FILTROUS:DESC --\u003e","brand":"Filtrous","offers":[{"title":"Default Title","offer_id":67691444994322,"sku":"DCM-PF-0500-P","price":105.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/filtrous.com\/products\/phosphate-buffer-ph-7-2-pharmaceutical-grade-dehydrated-500-g-unit","provider":"Filtrous","version":"1.0","type":"link"}
