The Dual Autotap tapped density analyzer for powders is simple-to-use, automated device which comply with a large number of internationally recognized standard methods.

• Two automatically rotating tapping stations
• 260 taps per minute
• 3 mm drop height
• Ensure the quality of raw materials and predict the flow behavior of powders
• Accommodates a wide range of graduated cylinder sizes for full flexibility
• Operates in accordance with a large number of international standard test methods

It provides a high level of test method control with a user-selectable, lockable number of taps. Tapping rate and drop height are fixed to provide consistent results from sample to sample. A large range of sample sizes can be accommodated with the use of a number of different graduated cylinder sizes.

Dual Autotaps has been used to provide customers with consistent, reliable bulk density and flowability values – essential knowledge for measuring pharmaceutical powders, metal powders, food powders, pigments, and more.

Dual Autotaps accommodate any single-piece glass-graduated cylinder with a hexagonal base. The tapping platforms have hole patterns and adjustable hold-down clamps so that any graduated cylinder from 5 to 500 ml may be used. There is also an adapter should you need to measure in a 1 L graduated cylinder.

The design of Dual Autotaps ensures compliance with all internationally recognized standard test methods describing the use of tapped density to determine bulk density involving a device capable of ensuring a drop height of 3 mm, a tapping frequency between 250 and 300 taps per minute, and the use of a specific type of graduated cylinder.
