| Size and
materials: |
|
1 cm x 1 cm PMMA
cuvette
1 cm x 1 cm Quartz cuvettes available for specification applications
such as high-temperature measurements |
| pH
range: |
Biological range (5.0-9.0) |
|
Temperature range: |
-5° C to +70° C for
PMMA cuvettes |
|
Accuracy: |
<1% of reading |
|

0.01 |
| Response
time: |
90% step response in 10
seconds |
| Factory
calibration: |
All cuvettes come with
factory calibration |
| Factory
calibration reset: |
User needs 2 buffers
(pH 1 and 11) |
| User
complete calibration option: |
Users have the option
to perform their own complete calibration |
| Sensor
signal: |
Absorbance at 620 nm
and 750 nm |
|
Expendable parts: |
The PMMA cuvettes
themselves are considered semi-disposable, meaning they can be used
multiple times, but they are not intended for long-term permanent
use |
| Usage
lifetime: |
Cuvettes should be
discarded and replaced once the maximum absorbance at pH 11 falls
below 0.1. |
|
Sterilization: |
Gamma, EtO |
|
Temperature compensation: |
Van't Hoff Correlation,
used for both discrete measurement pH correction and continuous pH
correction. |
|
Recommended
Spectrometer |
|
|
Configuration: |
Any UV-VIS spectrometer
can be used. Preferred spectrometer is 200-slit/grating-2/no lens. |
| |
Either LS-1 (with blue
filter) or white LED can be used as light source. |
