Smart Cuvettes Instructions
SC-PH-VIS1M-SAM-01-1109 9
Specification Value
Usage Lifetime Potential of being used as many as 50 or more measurements.
Lifespan depends on extent of exposure to high pH levels and
harsh chemicals. Discard after maximum absorbance at pH 11
falls below 0.1 (assumes reference of pH 1).
Recommended Spectrometer
Configuration Any VIS/NIR spectrometer can be used. Either LS-1 (with blue
filter) or white LED can be used as light source.
Temperature Compensation Factory calibrated pK values are adjusted based on the user-
inputted temperature via the van’t Hoff equation (see Algorithms
Used). Factory coefficients are generated at 22°C.
Chemical Compatibility:
PMMA
Glass
Aqueous solutions, ethanol/methanol solutions, ammonia,
peroxides, sodium hypochlorite solutions
All listed for PMMA plus concentrated acids (nitric, sulfuric,
acetic, etc) and acetone
Chemicals to Avoid for PMMA Concentrated acids (nitric, sulfuric, acetic, etc), acetone
Sterilization:
