In addition to calibration kit for ø16 mm glass tubes, now there are available calibration kits for ø18 mm glass tubes and for ø12 mm glass tubes.
BaSO4 Calibration kit for ø18 mm glass tubes is available for both Biosan densitometers: DEN-1 and DEN-1B. The BaSO4 standards must be shaken well before use. We recommend using vortex V-1 plus, which provides intensive mixing.
Calibration kit for ø12 mm glass tubes and adapter A-12 for ø12 mm tubes are available for densitometer DEN-1B only.
