Sartorius Analytical Balance
- Capacity: 220g
- Readability: 0.0001g
- Repeatability: ≤ ±1mg, Linearity: ≤ ±2mg
Sartorious analytical balances are tools widely used in gemology, not only for accurately weighing diamonds and gemstones but also for determining their relative density. The weight and density of a gemstone are crucial for its identification and valuation. The BSA224S Sartorious analytical balance offers high precision, sensitivity, and excellent repeatability, making it a reliable instrument for gemological analysis. Equipped with a hydrostatic weighing accessory, it provides accurate measurements, ensuring the ideal tool for professionals in the gemstone industry.

The weighing device (SG kit) uses Archimedes' principle in conjunction with the balance scale to measure the specific gravity of gemstones. This gemology tool is necessary for determining the density of gemstones, which plays a significant role in identifying their type. By measuring the weight in air and water and applying a formula, the specific gravity of the gemstone can be calculated.
