Most molecules have a net charge within a pH range of 2 to 10. When the pH is altered the net charge on molecules can change drastically. In this Ion Exchange Chromatography Kit a mixture of two chemicals is absorbed onto a solid support ion-exchange column and separated during elution under conditions that influence their net charge.Group Size: for 10 lab groupsStorage: Room temperatureTime Required: Complete in 60-90 minutesThe kit includes:Full instructionsIon exchangerChemical mixturePotassium Acetate bufferChromatography columnsAdditional required equipment & materials (not supplied with the kit):Spectrophotometer (B8L62443)Cuvettes (B8A60069 - 100pack)Retort Stand with clamp (B8R06571)Test tubes (B8R07897 - 100pack)Graduated glass pipette: (B8R05901)Pipette filler (B8A78062)
