Benefit :
PetLifeEliteR pHBuffer 4.01 SolutionTM is designed based on the new IC design of pH meter, so it is suitable for automatic calibrated and screwdrivers calibrated also.
Directions :
Shake well before using.
Low Ionic Strength (LIS) or high purity water measurements LIS solutions have very low buffering capacity and readily absorb carbon dioxide from the air. When a sample absorbs carbon dioxide from the atmosphere, carbonic acid forms. Carbonic acid decreases the sample pH and increases conductivity, causing inaccurate readings. One solution to this problem is to test the sample in a low volume, airtight sample chamber such as a LIS Chamber.
Initial use
1. Before measuring an LIS sample, soak the electrode in a solution similar to the sample in ionic strength and pH for 10 to 15 minutes.
2. Rinse the electrode with deionized water from a wash bottle.
3. Blot excess liquid with a soft paper towel.
4. Put the electrode in the sample.
Between uses
Between uses, in intervals of up to a two hours, the electrode can be stored in the sample (if the sample is not an extreme pH), or in a neutral LIS solution such as tap water.
Rinse the electrode before use to prevent sample contamination.

Important Note:
If pH electrodes are stored in LIS samples for a long period of time, the electrode life may be shortened. After measuring the LIS samples, put electrode back into the electrode storage solution or 3 M KCl.
