Bulk Density Apparatus – 951 is a specially designed to study the packing down of powder beds of different pharmaceutical and chemical powders, flakes, pellets, granules and other bulk substances. Bulk Density is an essential test required in the process of tablet, capsule filling and cosmetic manufacturing.

The system is equipped with microcontroller based digital display for displaying accurate and exact stroke count and soft touch membrane type keys for ease of operation. The system has ‘SET’, ‘UP’ and ‘DOWN’ keys, for setting the total number of required strokes (Set Count) for the current measurement session. User can set to any number of required strokes within the range from 1 to 9999 counts. The system automatically stores the last ‘Set Count’ value which is retained in the memory even when the instrument is switched off. Each stroke count is displayed on the 4 digit seven segment bright red LED display on the front panel. A common lock cushioned holder for both the cylinders drops down smoothly from the height and holds the cylinders. The Up/Down (i.e. Tapping) movement of the cylinders stop automatically at the ‘Set Count’ value. An audible alarm sound indicates that the current measurement session is over.

In case of power failure, the last counts are retained and the instrument starts counting automatically from the point of power failure. The instrument uses the latest microprocessor technology and advanced engineering techniques so as to give enhanced accuracy and reproducibility.

Microprocessor Tap Density Tester, Model 1951 is a density measurement equipment used to measure tapped density of powders, as well as granulated or flaked materials by standardized and repeatable procedures. Instrument uses the latest microprocessor technology and advanced engineering techniques so as to give enhanced accuracy and reproducibility.

System is equipped with 4 line alphanumeric LCD display with backlit and 16 number of soft touch membrane type keys.

The unit is provided with two motorized platforms which allow for 14 ± 2.0 mm drop height for the USP Method I version, and a 3 ± 0.2 mm drop height for the USP Method II version. The motorized platforms consist of two cylinder holders with snap-lock mechanism designed to hold 100 ml and 250 ml cylinders. The simultaneous rotating and tapping motion minimizes any possible loss of mass during tapping down.

The instrument stores the test parameters, readings and results simultaneously in the memory which are retained even after the power is switched OFF. Provision has also been made for attachment of a printer so as to provide hard-copy printouts of test data, including the time, date and calculated results.
