Storage Conditions: To ensure a quick response and free flowing junction, the sensing bulb and reference junction must not dry out. Short Term Storage (up to one week) Soak the electrode in ROSS pH electrode storage solution, Cat. No. 810001.
Long Term Storage (more than one week) Fill the reference chamber and securely cover the fill hole. Cover the sensing bulb and reference junction with the protective cap, sleeve or storage bottle containing a few drops of storage solution.
- Clinical, pharmaceutical, and food labs, wherever sample size is a constraint
Thermo Scientific Orion ROSS® pH Electrodes
The standard for accurate, reproducible pH measurements
ROSS Specifi cations :
Slope: 92-102% of theoretical
Nernst slope
Isopotential point: pH 7
Accuracy of measuring a pH 6.86
buffer after standardization at 25 °C:
Accurate within 0.03 pH for buffer
at any temperature between
0-100 °C using automatic temperature
compensation.
Speed of response in 6.86 buffer going
from 25 °C to 75 °C: Response stable
to 0.01 pH within 30 seconds
Speed of response between 6.86
and 4.01 buffers at 25 °C: Response
stable to 0.002 pH within
15 seconds
Mercury free, TRIS, protein and
sulfi de compatible
Temperature Response
The ROSS electrode continues to show fast
reproducibility and accuracy after many,
dramatic temperature changes.
