Description
HI6007 is a pH 7.010 calibration buffer with a high accuracy of ±0.002 pH. The HI6007 is NIST traceable and supplied with a Certificate of Analysis. The pH value is 7.010 ±0.002 @ 25°C. A temperature chart of the actual pH value at various temperatures is printed on each bottle.
This line of buffers with millesimal accuracy (±0.002 pH), HI 60xx, has been prepared to meet the increasing need for assured accuracy in pH measurements, making it possible to achieve a resolution of 0.001. Each bottle of the series HI 60xx is provided with a certificate of analysis, prepared by comparison with NIST standards. The buffers have the lot number and expiration date clearly marked on the label and are air tight with a tamper-proof seal to ensure the quality of the solution. They have been specially formulated to have an expiration of 5 years from the date of manufacture for an unopened bottle. The buffers are packaged in light block bottles which prevent any oxidation from UV light that could alter the buffer value.
The premium quality pH buffers are produced in accordance with ISO 3696/BS3978 standards using hihg purity salts, deionized water, certified weight-checked balances, and Class A glassware in a temperature controlled environment monitored with certified thermometers. The Certificate of Analysis has the following data:
- Product code
- Lot number
- Mean lot value
- NIST Standard Reference Materials (SRMs) that were used
- Manufacture date
- Expiration date
The color coded label on the HI 60xx series packaging correspond to a given standard pH value. They make it easy and safe to identify the buffers to be used without containing any dyes that may stain the reference cell of a pH electrode.
This series is also available in handy sachets to perform accurate calibrations on-site or in the field. Single dose sachet solutions are safe, easy to carry and always fresh.
