pH 7 buffer solution 20 ml (pH 7.00 at 25 \u00b0C) for precise calibration of your pH probe<\/a> or pH meter<\/a>. NIST traceable. Sachet of 20 ml, sold per 25 pieces. One sachet, one calibration. Always fresh buffer solution for a reliable calibration. The expiry date and lot code are on the sachet. This buffer solution is also called pH calibration solution.<\/p>\n Also available as pH 7 buffer solution 250 ml<\/a> and pH 7 buffer solution 60 ml<\/a>.<\/p>\n Do you also calibrate at pH 4? Choose pH 4 buffer solution sachet 20 ml<\/a> or pH 4 buffer solution 250 ml<\/a>, or both values together in the pack pH 4 and pH 7 sachet 20 ml<\/a> or pH 4, pH 7 and 475 mV sachet 20 ml<\/a>. All values: pH buffer solution<\/a>.<\/p>\n Open the sachet and place your pH probe directly into it. You do not need a beaker. Calibrate at pH 7 as the manual of your meter requires and then throw the sachet away. This way you calibrate quickly, with one sachet per calibration. Sachets are handy to take anywhere.<\/p>\n Yes, in 99 % of applications. The difference of 0.01 is smaller than the precision of a standard pH meter or pH probe. Only for a laboratory with a very accurate measuring instrument do we recommend pH 7.01. Our pH 7.00 buffer solution is made and correct at 25 \u00b0C.<\/p>\n pH 7 buffer solution fits all brands of pH probes and pH meters, including Sugar Valley, Hayward, Zodiac, AstralPool, Bayrol, Hanna, Milwaukee, Seko and Kripsol.<\/p>\n Store the buffer solution in its original, tightly closed packaging, cool and dry at 15\u201325 \u00b0C, protected from frost and direct sunlight, and away from strong acids or oxidising agents.<\/p>\n\n
