TAITEK pH Buffer Solution pH4.00/pH6.86/pH7.00/pH9.18/pH10.00 Calibration Solutions for pH Meters (100 mL)

pH Buffer Solution 4.00 6.86 7.00 9.18 10.00 Calibration Solutions for pH Meters (100 mL) Instructions for use : - Always rinse probes with tap water or purified (deionized) water before calibration. - Pour out the solution(25 mL) into a small and clean beaker and submerge pH probe in the solution. - Stir the probe gently, wait for the reading to be stable and perform calibration of pH meter. - After the calibration is completed. The used solution must not be poured back into the bottle. Because it will cause the solution in the bottle to be contaminated. - The pH meter should be calibrated at least once a month or may be once a week. Depending on how heavy you use pH meter. If the meter was keep for several months, it is recommended to calibrate the meter first before using it. Because the pH probe will gradually deterioration over time, this causes the measurements to be deviated. - When storing pH or ORP meter, user should always keep the probe immersed in the Storage solution (KCl 3.3M) to prolong the service life. *If the probe is stored in tap water, distilled water, deionized water, the probe will quickly deteriorated when left immersion.* - Store solution at room temperature with closed cap. - After opening the bottle, it is recommended to use within 3 - 6 months for the best result. If the bottle has been opened for more than 6 months, depending on whether the user can accept it because the value may be slightly deviated, for example pH 7 may be 7.1 to 7.2. - For laboratory and industrial use only. Product : Storage solution (KCl 3.3M) You can type the name of the product to see more in the store's search box. Attention : - User should know the meter specification which solutions are compatible. - There are 2 types; EU Standard 4.00 7.00 10.00 or Asia Standard 4.00 6.86 9.18 - If the specification is unknown. You can chat and consult first, in order to help you look at the specification and prevent buying the wrong solution. pH calibration solution ; 1 bottle , 100ml Calibration solutions packed in 100ml durable plastic bottles-economical and convenient for industrial and laboratory use.
