EUR. 6.8 Method 1 (harmonized) (metallic powders) (formed catalysts) (fine catalysts) (dried milk) (pigments) (metallic powders) (instant coffee) (dried milk) (uranium dioxide powder) (pigments) (metallic powders) (metal powders) (pharmaceutical powders) (pharmaceutical powders) (pharmaceutical powders) (pharmaceutical powders) To measure tap density, samples are placed in standard graduated cylinders and mounted on a universal tap platform designed to accommodate cylinders from 10mL to 500mL. After noting the initial volume and weight of the material, the number of desired taps is entered and tapping started. When the specified number of taps is completed, tapping stops automatically. Reading of the powder surface is facilitated by automatic rotation of cylinders during tapping which promotes a flat powder interface. If the material characteristics are unknown, tapping may be done step-wise by user specified numbers of taps, while noting or graphing the results until the volume becomes constant. Once the tapping behavior is known, the proper number of taps, typically thousands, including a significant excess (to account for future variability between samples) can be preset on subsequent runs, thus freeing the operator for other work. A noise reduction cabinet is available which can reduce the tapping noise levels by 15 dBA* or more. * Actual improvement depends on local factors such as bench, ceiling height etc The apparent bulk densities of powdered, granular of flaked materials are highly dependent on the manner in which the particles are packed together due to cohesion and shape effects. Furthermore, handling or vibration of particulate material causes the smaller particles to work their way into the spaces between the larger particles. The geometric space occupied by the powder decreases and its density increases. Ultimately, no further natural particle packing takes place with- out the addition of pressure and maximum particle packing is achieved. Under controlled conditions of tapping rate, tap force drop and cylinder diameter, this condition of maximum packing efficiency is highly reproducible. Tap density measure- ment is formalized in a number of international standards to which both Autotap models conform.

ACCESSORIES cabinet Noise Reduction Cabinet A sound-insulated enclosure is available that accommodates either Autotap model. The noise from tapping can be reduced by up to 15 dBA (actual improvement depends on local factors such as bench material and ceiling height). The doors can be locked for added safety and security.
