you have acquired a high-quality accessory to your electronic balance. This accessory kit will ease your daily work load. Please read the Installation and Operating Instructions carefully before setting up your density determination kit and working with it. If your balance is equipped with a density determination program, you can have the rho values calculated by the program. In this case, please follow the ope ...

You can use the density determination kit, YDK 01or YDK 01-0D, with the following balances: – ME series balances (Genius series) – BA balances with a readability ≤ 0.1mg – BP/LA balances with a readability ≤ 0.1mg – MC balances with a weighing range of 210 g and up (Micro series) – RC balances (Research series) Preparing the Bar Frame You must mount the adapter before the bar frame can be placed on the balanc ...

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. Always use the metal platform to hol ...

Installing the Density Determination Kit G Remove the draft shield cover, glass plate, weighing pan and base from the balance LA/LP Balances, Except Model LA/LP3200D G Place the components on the balance in the following order: – Compensating ring – Bar frame k The wedge-shaped opening at the top of the bar frame should face the direction from wh ...

Draft Shield G Place the components on the balance in the following order: – Longer adapter – Compensating ring – Bar frame k The wedge-shaped opening at the top of the bar frame should face the direction from which the sample holder (pan hanger assembly/glass plummet) will be placed on the balance Beaker/Immersion Device G Use the metal plate to support the beaker. Place it on the bar frame base and then se ...

their density is less than that of the liquid in which the sample is immersed, use: – 76 mm Ø beaker and sieve for immersing the sample To determine the density of liquids: – 55 mm Ø beaker and glass plummet Thermometer If necessary, attach the thermometer to the rim of the beaker using the retainer clip. 12 ...

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. With a hydrostatic balance which enables you to weigh a solid in air as well as in water, it is possible to: determine th ...

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. – The density of the liquid causing buoyancy depends on its temperature – Air buoyancy during weighing in air – The change in the immersion level of the pan hanger ass ...

– 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 (fl). Air Buoyancy A volume of 1cm of air has a weight of approximately 1.2 mg, depending on its temperature, humidity ...

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. The “Supplement” to this manual shows how this correction factor is derived. Adhesion of Liquid to the Wire When the ...

Determining the Specific Gravity of Solids Preparation (Distilled water is used in the description) – Center the large-diameter beaker (76 mm Ø) on the metal platform – Fill it so that the distilled water is approximately 5 mm below the rim – Add three drops of tenside to the distilled water – Attach the thermometer to the rim of the beaker using the retainer clip – Clean the sample holder with a solvent ...

– Read off the temperature of the liquid – Using the tables at the back of this manual, find the density ρ (fl) which corresponds to the temperature measured for the liquid you are using – Calculate specific gravity using the following formula: ρ = W (a) · [ρ (fl) – 0.0012 g/cm3] + 0.0012 g/cm3 0.99983 G W (a) and G in g; ρ (fl) in g/cm3 G = W (a) – W (fl) Determining the Specific Gravity of Solids with a Den ...

Here, use a liquid for causing buoyancy with lower density than that of the solid for which the specific gravity is to be determined. We have had good results with ethanol (up to a density of approx. 0.8 g/cm3). The density ρ (fl) of ethanol (with regard to its temperature) can be found in the table in the supplement. The negative effect of the liquid’s surface tension on the results is less noticeable ...

Determining the Weight of the Sample in Air – Tare the balance – Place the sample on the frame weighing pan and weigh – Record the weight W (a) Determining the Buoyancy G = W (a) – W (fl) – Tare the balance again (with the sample on the frame weighing pan) – Place the sample under the sieve or immerse it below the surface of the liquid using the sieve1) – Record the buoyancy “G,” which is displayed w ...
