Tapped Density Tester

The Tapped Density Testers Series JV have been designed to measure the tapped density of powders, granules and similar products in accordance with USP Chapter Method 2 and EP Chapter 2.9.34. Tapped density is achieved by mechanically tapping (raising the cylinder and allowing it to drop a specified distance under its own weight) a measuring cylinder containing the sample under test. Two versions of the tester are available dependent on the number of test stations required (1 or 2).

Tapped Density Tester for Powders: Series JV

The Tapped Density Testers Series JV have been designed to measure the tapped density of powders, granules and similar products in accordance with USP Chapter Method 2 and EP Chapter 2.9.34. This technique is particularly useful in powder flowability studies and also in determining the amount of settlement during transit to optimise pack sizes e.g., washing powders, etc.

Tapped density is achieved by mechanically tapping (raising the cylinder and allowing it to drop a specified distance under its own weight) a measuring cylinder containing the sample under test.

Two versions of the tester are available dependent on the number of test stations required (1 or 2).

Both of the instruments concerned are equipped with membrane keypads for setting the number of strokes or time and an LC display to set the appropriate parameters and monitor the progress of the test.

Mode of operation

The mode of operation is identical on both models:

  • Weigh out a predetermined amount of the sample, say 100 g /- 0.1%, and place it in the graduated cylinder provided and note the unsettled volume. Secure the graduated cylinder to the test platform of the tester using the bayonet fitting provided for this purpose.
  • Unless otherwise specified, set the number of taps via the touch sensitive keypad on the front of the instrument to 500 and operate the device making a note of the resulting tapped volume. Repeat this operation for a further 750 taps noting the volume once again.
  • Continue repeating the test in increments of 1250 taps until the difference in tapped volume is less than 2%. Note the final reading.
  • The tapped density in grams per ml can now be calculated by dividing the sample weight by the final tapped volume.
  • Measures of the ability of the powder to flow and its compressibility can now be given in the form of the so-called Hausner ratio (Tapped Density/Bulk Density) and the Compressibility Index ((Tapped Density – Bulk Density/Tapped Density) x 100).
  • In a free flowing powder, inter-particulate interaction is less significant and unsettled and tapped densities will be closer in value. In poorly flowing powders, the inverse is to be expected.
  • It follows that the closer the Hausner ratio is to one, the better the flow. Powders with poor flow generally have a ratio of greater than 1.25.

The Tapped Density Testers measures 280 mm wide x 250 mm deep x 670 mm high.

Higher Raman Sensitivity Than Ever Before Possible

The HyperFlux PRO Plus redefines what is possible with process measurements using the power of Raman spectroscopy. The newly re-designed HTVS component enhances the spectral throughput by an order of magnitude over conventional designs providing superior photon management. This allows process measurements to be done faster and with better sensitivity.

  • More accurate identification and quantitation
  • Faster measurement
  • Lower laser power operation
  • Flexible chemometric options including Unscrambler, Simca-P+, Pirouette,  Eigenvector.
  • 21CFR11 and IQOQPQ option for GMP applications.
  • 8-channel multiplex option.
  • ATEX option available with OPIS35

Hyperflux PRO Plus -  HTVS Raman Spectrometer

ATEX rated. On-line/In line and Reaction monitoring

Tornado’s HyperFlux PRO Plus is a complete Raman spectroscopy system including a proprietary HTVS-enabled spectrometer, a high-quality stabilised laser, multiple laser safety interlocks, temperature monitoring and dynamic re-calibration, and automated system health monitoring and fault detection. This powerful, reliable, and easy-to-use instrument is contained in a small, lightweight, cost-effective package which is readily deployed in both in-line process and laboratory settings.

The HyperFlux PRO Plus redefines what is possible with process measurements using the power of Raman spectroscopy. The newly re-designed HTVS component enhances the spectral throughput by an order of magnitude over conventional designs providing superior photon management. This allows process measurements to be done faster and with better sensitivity. The HyperFlux PRO Plus is perfect for ATEX situations where the highest sensitivity is required. Put Raman to work in your process measurement scheme.

The HyperFlux PRO Plus offers customisable bandpass, resolution, and throughput configuration delivering high-performance with versatility to meet your application requirements:

  • 4 cm-1 spectral resolution with no slit
  • Configurable for a variety of applications
  • Stand-off and immersion probe optics
