VWR®, Density standards referenced at 20 °C
标准品 Density Standards
These products can be used as calibration standards for density measurements by pycnometric, vibrational or hydrometer-based techniques.
- High accuracy across an extensive density range (0,6619 to 3,1096 g/ml) at 20 °C
- No toxic heavy metals used in any formulation
- Can be used with any brand or type of density measuring instrument
- Supplied in a high quality, tamper-proof, amber glass bottle
These standards are prepared gravimetrically (solute and solvent) using OIML traceable weights. The density values of the standards are established using fully calibrated reference pycnometers.
Certifications: In accordance with ASTM D1480-12 for testing of density or relative density. A certificate of calibration is issued in accordance with the requirements of ISO/IEC 17025.
