Technical buffer solutions for WTW meters with pH functionality
All modern technical buffer solutions are traceable to PTB (Physical Technical Government Agency) or NIST (National Institute of Standards and Technology, USA).
Their accuracy is ± 0,03 pH. Every bottle has ist own lot reference with the expiration date.

Highlights:
- Shelf life up to 3 years (unopened)
- Economic consumption
- Easiest handling by use of the dosing vessel (250 ml and 1 L bottles)
- Every bottle has ist own lot reference with the expiration date
- Accuracy is ± 0,03 pH
Technical buffer solutions pH 2.00, pH 4.01, pH 7.00 and pH 10.01: pH 4.01, pH 7.00 and pH 10.01 are available in the practical 250 ml bottles including dosing vessel (TPL 4, TPL 7 and TPL 10.01 Trace) as well as in 1 l special bottles with dosing vessel and nozzle (TEP 4, TEP 7 and TEP 10.01 Trace).
For single use 50 ml STP bottles are available: STP 4, STP 7, STP 10.01 Trace.
The special buffer pH 2.00 is available in 1 l bottles. This allows you to adapt the bottle sizes easily to your individual use.
