Technical Buffering Solutions (buffer bottles)
pH buffers by WTW – precise and traceable to PTB/NIST in two bulk sizes of 250 ml or 1 liter with built-in dosing vessel standard buffer
Technical buffering solutions (buffer bottles)
Technical buffering solutions for 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 device (TPL 4, TPL 7 and TPL 10.01 Trace) as well as in 1 l special bottles with dosing device and pour spout (TEP 4, TEP 7 and TEP 10.01 Trace). The special buffer pH 2.00 is also available in 1 l bulk. This allows you to adapt the bulk sizes easily to your individual use.
The buffer 10.0 is a special case: It is only still suitable for inoLab® device of the series level 1, 2, 3, portable meters 3xx as well as for various other old devices!
All modern technical buffering 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 its own lot reference with the expiration date.
- Life up to 3 years (unopened)
- Thrifty use
- Easiest handling by means of a dosing device
