Page 8: Getting Started
Getting Started YDK 01, YDK 01-0D You can use the density determination kit, YDK 01 or YDK 01-0D, with the following balances: – ME series balances (Genius series) – BA balances with a readability ≤ 0.1 mg – BP/LA balances with a readability ≤ 0.1 mg –... - Page 9 Screw the appropriate adapter into the underside of the bar frame base. Now remove the following components from the balance: – weighing pan – compensating ring for BA and BP balances – pan support for BA and BP balances Place the frame in the weighing chamber. The wedge-shaped opening at the top of the frame must face the direction from which the sample holder (sieve/glass plummet) will be placed into the frame.

Page 13: Methods For Determining Specific Gravity/Density
Methods for Determining Specific Gravity/Density The Archimedean principle is applied for determining the specific gravity of a solid with this measuring device: A solid immersed in a liquid is exposed to the force of buoyancy. The value of this force is the same as that of the weight of the liquid displaced by the volume of the solid. -
Page 14: Sources Of Error And Possibilities For Correction
Sources of Error and Possibilities for Correction The formula on the previous page for determining the specific gravity of solids is sufficient to obtain an accuracy of one to two decimal places. Depending on the accuracy you require, consider the following error and allowance factors. - Page 15 To correct the liquid density for temperature, proceed as follows: – measure the temperature of the liquid using the thermometer that comes with the kit – use the table at the back of this manual to find the density of the most commonly used liquids, water and ethanol, at the temperature measured, and use this density for the value ρ...
- Page 16 Use the following formula to correct this error: W (a) · [ρ (fl) – ρ (a)] ρ = + ρ (a) 0.99983 [W (a) – W (fl)] Since the correction factor is determined exclusively by the geometry of the measuring device setup, be sure to only use the large diameter beaker (76 mm) from the kit when determining the specific gravity of a solid.

Supplement This supplement should help you to better understand how the formulas and allowance factors used have been derived. Fundamental Principles Mass (g) Density = Volume (cm The Archimedean Principle: A solid immersed in a liquid is exposed to the force of buoyancy (G). This value is the same as that of the weight of the liquid displaced by the volume of the solid. - Page 26 The density of a liquid is determined from the buoyancy of the plummet, which has a defined volume ρ (fl) = where: = specific gravity of a solid ρ ρ (fl) = density of the liquid W (a) = weight of the solid in air W (fl) = weight of the solid in liquid = buoyancy of the plummet = volume of the solid...
