Generally the capacity of the bottle should be greater than not equal to the final volume of media to be prepared in order to prevent the media from boiling over during the autoclave step.

Kpo4 recipe. PACKAGE INSERT Potassium Phosphates Injection PI-ENG-v10 Page 1 of 4. After the solid is completely dissolved dilute the solution to a final volume with deionized distilled water. This online resource may be cited as follows.

Add 80 of the final volume of dH2O to a sterile media bottle. 1 02M KH2PO4 g l. In general your total moles of phosphate are Concentration x Volume obviously but you divide it between the monobasic acid.

Cholesterol stock solution 5 mgmL in ethanol 1. Dissolve 3 gL NaCl and 25 gL bacto peptone in H 2 O. Add 0888 g of KH 2 PO 4 to the solution.

Monopotassium phosphate MKP also potassium dihydrogenphosphate KDP or monobasic potassium phosphate KH2PO4 is a soluble salt of potassium and the dihydrogen phosphate ion. Russell for the preparation of potassium phosphate buffer from potassium phosphate stock solutions at various pH values. Alternatively make buffer without 2 -mercaptoethanol and store at room temperature.

05 uL PanK 15 uL H2O. Ensure you have a volumetric flask measuring your desired autoclave volume. 17022020 The goal of a buffer solution is to help maintain a stable pH when a small amount of acid or base is introduced into a solution.

The pH of the dibasic will be alkaline around pH 8 and the monobasic will be weakly acidic around 65 maybe 68. Electrophoresis sample buffer 2x. Add 16282 g of K 2 HPO 4 to the solution.
