– Bulk Density Tester series testers are used to measure apparent density, bulk factor, and where applicable, the pourability of plastic materials such as molding powders.
RT-730 Apparent Density Tester is used to measure apparent density, bulk factor, and where applicable, the pourability of plastic materials such as molding powders. It is the ideal tester for chemical industrial and plastic manufacturing. The mass of loose material (powder or granular material) can be poured from a funnel of specified design to a unit of specified volume. The density can be obtained through the volume and the weight of materials in the unit.
Standard Test Methods for Apparent Density, Bulk Factor, and Pourability of Plastic Materials 1; Apparatus for Apparent, Density Test, Method A and B;
Bulk density the mass of loose material per unit volume, including the pores within particles and the Spaces between particles. Synonym: apparent density.

Test Method C (see FIG. 3) covers the measurement of the apparent density of materials supplied in the form of coarse flakes, chips, cut fibers, or strands. Such materials cannot be poured through the funnels described in Test Methods A and B. Also, since they ordinarily are very bulky when loosely poured and are usually compressible to a lesser bulk, even by hand, a measure of their density under a small load is appropriate and useful.
