VWR®, Refractive index standards
Refractive index of each standard is verified using a calibrated and temperature controlled refractometer.
- Standards are prepared gravimetrically on weight/weight basis
- Solute (sucrose) and solvent (water) are weighed on a calibrated balance using OIML traceable weights
: Certificate of Calibration is issued in accordance with the requirements of ISO/IEC 17025.
- Environmentally Preferable:
