The Labmart DK-250 Density Kit for Weighing Scales is designed to support liquid density determination using a compatible laboratory balance. Suitable for balances with a weighing pan diameter below 125 mm, the kit includes a beaker, beaker stand, density kit bracket, two hanging holders and a thermometer. It can be used with balances that have a density measurement function or with balances where density is calculated manually from weight measurements in air and in a liquid.

Key Features

• Liquid density testing: Supports density determination using compatible weighing balances.

• Balance compatibility: Specified for balances with a pan diameter below 125 mm.

• Flexible measurement method: Can be used with a compatible balance density function or manual calculation.

• Complete test arrangement: Includes a beaker, beaker stand and density kit bracket.

• Hanging holders included: Supplied with two holders for the test setup.

• Temperature measurement: Includes a thermometer.

• Laboratory accessory: Suitable for density testing and related quality-control procedures.

   Working Principle

   The density of a liquid can be determined from suitable weight measurements and the appropriate calculation method.

   For the manual method described in the product information:

   \[ \rho_{\text{sample}} = \frac{W_{\text{air}}\times SG_{\text{fluid}}} {W_{\text{air}}-W_{\text{fluid}}} \]

   Where:

   • \(W_{\text{air}}\) = weight measured in air

   • \(W_{\text{fluid}}\) = weight measured while immersed in the reference fluid

   • \(SG_{\text{fluid}}\) = specific gravity of the reference fluid, used as specified by the calculation method

   The measurements must be obtained using a suitable setup, and the fluid properties and units must be handled consistently. Follow the balance manufacturer's procedure for the selected density determination method.
