pH Tester Cleaning Kit 

Includes:  (2) Thermo Scientific Nalgene® economy low-density polyethylene 4 oz. (125 ml) wash bottles

Fill one bottle with alcohol.  Fill second bottle with pure water (DI, RO, or distilled).  Rinse the pH meter bulb first with alcohol, then with the water.  Put a couple drops of the pH test solution on the bulb and then put the cap on for storage.

Wash bottles feature a one-piece molded polypropylene (PP) closure and stem that eliminates leaks and a PPCO draw tube. The tip can be cut back to increase flow. Delivery tube is welded into the closure to prevent separation.
