SILICONE SPHERE

• Mass : 500g
• Diameter : 7 cm
• Material : Silicone

We also provide volume and mass silicone sphere calibration services (traceability to National Metrology Institute)

SILICONE SPHERE INFO

Silicone is a stable material. This silicone sphere of known mass and volume are replacing distilled water as the density primary standard. This silicone sphere are used as density standard for determining the density of solid and liquid by the hydrostatic weighing method. Advantages of using silicone sphere as density standard:

• Easily to determined the density of an unknown liquid

• Mass and volume of silicone sphere are directly traceable to the base units of length and mass
