Type 1, Lipkin Type 2, Sprengel Type 3, Gay-Lussac, Adjusted Type 3, Gay-Lussac, Unadjusted Type 4 Reischauer Type 5 Hubbard
Pyknometers are used to determine the specific gravity of a liquid. Type 3 to 5 are also known as Density Bottles. There are a number of different styles listed above. We routinely supply the Gay-Lussac Type 3, but can supply others if required. Please contact usfor details.
Usage Guide
For basic measurement of specific gravities in qualitative work an Unadjusted Density Bottle is sufficient. Typical usage might be measurement of density of salt/water or solvent/water mixtures to derive the ratio of the mixture. Used in schools, universities and research laboratories.
For more accurate measurements an Adjusted Density Bottle is appropriate. Adjusted Density Bottles are calibrated to a tolerance with a unique serial number for traceability. A certificate of accuracy traceable to national standards can be provided if required. Adjusted Density Bottles are used in analytical labs, in breweries for measuring alcohol content and other controlled environments.
