Density Standards

Specifications: Weighted, hermetically sealed, amber glass capsules; 1/4″ (6.4 mm) OD, 3/4″ (19 mm) long, slightly longer for higher densities; permanently marked for identification; precisely calibrated at 23°C (73.4°F) unless otherwise specified.

Application: Sink-Floats are usually selected to meet specific density liquid monitoring or individual liquid density requirements by ordering singly, in pairs, or in series by Catalog No.

Application: Sink-Float Screening Sets are available in series commonly used in making quick estimates of densities.

The precise density of a Sink Float Standard within a set may not end in a “0” or a “5”. However, its precise density will be clearly marked and calibrated within the chosen tolerance (i.e. A nominal 1.00 gm/cc Standard for Set #13550 will be marked with its density within its tolerance so its density will be a number between .995 and 1.005 and marked as to its actual density).

Standard Temperature: Calibration will be at 23°C unless another temperature is specified. See below.

Temperature Adjustment Charge: For other than 23°C Use CAT # 13200; $111.00 (For each combination density-temperature specification in a single order)
