Stabilize glassware on orbital or rocking shakers and eliminate slippery conditions on benchtop surfaces with this versatile non-slip safety mat.

The Universal Specific Gravity Kit is designed to be used with any electronic scale with a minimum capacity of 15 grams and a tare (re-zeroing) function to easily measure the specific gravity of gemstones and minerals.
Just weigh the stone "in air" on the integrated weighing platform of the scale, then without changing the setup, weigh the stone in water by placing it in the underwater weighing pan of the gem holder suspended above the platform. Plug the two values into the specific gravity equation and obtain the specific gravity of your stone.

Includes: lightweight gem holder support and underwater weighing pan, independent, spill-resistant, adjustable beaker support, beaker for filling with water - 100ml 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.

Syringe filters are available with a choice of membrane type: Polyethersulfone (PES) for low protein binding and faster flow rates; surfactant-free cellulose acetate (SFCA), with or without prefilter, for lowest protein binding; Polytetrafluoroethylene (PTFE) for chemical resistance; regenerated cellulose (RC) – the best choice for DMSO compatibility; and nylon (NY) which is hydrophilic, surfactant-free and lowest extractable.

Simple and easy to use design.
