VWR®, Density standards referenced at 50 °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 (0,6668 - 3,0721 g/ml) at 50 °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.
