Fast Response with Low-Ionic Strength Samples Beckman Coulter
STAR electrodes have been specially designed using a unique glass formula to
provide rapid response for samples with low ionic strength and when sample
temperatures differ significantly.
The following performance specifications will be met:
| Response Time: |
25ºC to 75ºC in pH 4 buffer; stable to ± 0.02 pH
in less than 30 seconds. With pH 3 to pH 7 buffer at constant
temperature; stable to ± 0.01 pH in less than 30 seconds |
| Accuracy: |
Relative to NIST certified buffers; ± 0.01 pH |
| Slope: |
97 to 100% |
| Isothermal Point: |
7.0 pH |
| Stability: |
± 0.002 pH over 24 hours |
