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.
