Description
HI 7001L is a pH 1.68 ± 0.01 pH @ 25°C Buffer Solution, which allows calibration of a pH meter for acidic ranges. It is supplied in a 500 mL bottle.Plating bath samples, food samples and waste samples are often acidic in nature. To increase accuracy of your measurement at lower pH, it is important to calibrate your electrode and meter at that pH also. This Buffer solution allows fulfillment of this requirement by bracking of the lower pH samples by using this buffer in conjunction with a second buffer with a value of pH 4.01 or near pH 7.01. Features:
- Produced in accordance to ISO 3696/BS3978 standards using high purity salts, deionized water, certified weight-check balances, and Class A glassware in a temperature controlled environment monitored with certified thermometers
- Air tight bottle with tamper-proof seal to ensure quality and freshness
- Each bottle marked with lot number and expiration date
- Formulated to have an expiration of 5 years from manufacture for an unopened bottle
- Color-coded label for easy pH identification
- Solution does not contain any dyes that may stain the reference cell of a pH electrode
- Temperature chart of the actual pH value at various temperatures on each bottle
