Universal Specific Gravity Kit for an Electronic Scale

This Universal Specific Gravity Kit enables fast and convenient measurement of the specific gravity of gemstones, minerals, and other solid materials. Its user-friendly above-the-scale design allows samples to be weighed in air and underwater without changing the setup.

 

This version of our Universal Specific Gravity Kit can be used with virtually any Bench or Lab size Electronic scale, provided that:

• The scale has a minimum capacity of 50 grams.
• FYI, the "tared weight" of that portion of the kit that sits on the weighing platform is about 26 grams, so this must be subtracted from your scale's listed capacity to derive available capacity for specific gravity measurements.
• The scale has a tare (re-zeroing) function.
• The scale's weighing platform is large enough to accommodate the 3.25" diameter base of the kit's Underwater Weighing Pan Assembly.
• If the scale has a draft shield or lid, it must be either removable, hinge back away from the scale, or designed such that the front and 1 side door can be opened.
• If your scale has a draft shield that remains in place, its inner dimensions must be large enough to fit our Tri-Wire Weighing Pan Assembly which is 7" high and 4.5" across.

Delivery information: Includes: lightweight gem holder support and underwater weighing pan, independent, spill-resistant, adjustable beaker support, beaker for filling with water - 100 ml capacity, aluminum test weight, stainless steel tweezers, instructions, reproducible Specific Gravity worksheet, table of 300 common minerals/gems sorted by SG, with 6 other properties, including refractive index.  
Note: shown with Boreal Balance - not included.
