The Quick and Easy Way to Assess Density in Laboratory Applications
Most scientists know that accurately determining the density of a substance is a critical part of the research process. A density kit is a valuable accessory to help laboratory workers assess the density of a material. By adding a density kit with an analytical balance the process becomes simple.
Traditionally, density determination measurements were calculated by:
- Figuring out the volume
- weighing the sample
- Dividing the volume by the mass
- Then finally coming up with the density
This process is not only complicated and tedious; it can be inaccurate.
Testing of both solids and liquids is possible using the density kit. That means that even samples with densities greater or less than that of water can be determined. The lab balance software will calculate density using water, ethanol or paraffin as selectable references. The software in the lab balance also allows the user to enter the density of any reference liquid directly.
The diagram above shows one example of what a density weighing kit set-up on a lab balance may look like. The density kit is installed on the floor of the balance's enclosed weighing chamber. The kit's beaker holds the reference liquid and may be reused to test as many samples as needed. The user simply selects the density application from the built-in menu options. If a reference liquid is used other than what is already programmed into the lab balance, the user can enter the density for that reference liquid.
The application prompts the user through the process:
Weigh the sample in air using the sample cup on top of the stand, then in the reference liquid using the sample cup suspended on the wire.
