The PTG-M100 manual powder tester is used to measure the flow behavior of granules and powders in compliance with the EP <2.9.36>, EP <2.9.16>, USP <1174> Pharmacopoeia and ISO 4324 standards. This instrument is used to determine the powder flow time and the powder’s angle of repose. By using a laboratory balance also weight, density and the volume of the powder cone can be calculated. Furthermore, the EP “flowability” result can be calculated by measuring the flow time of 100g of sample.

The PT-SV110 Scott Volumeter determines bulk density of powders according to the following standard Monographs: ISO 3923-2 (metallic powders): determination of apparent density, EP <2.9.34.1> USP <616, Method II> bulk density and tapped density of powders and method II, ASTM 32990 standard test method for apparent density of metal powders and compounds. The PT-SV110 is applicable to powders including metal powders, compounds, pigments, and so on that will flow freely through a suitable nozzle.

PT-TD300 is used to test the tapped (or “tamped”) density and apparent density of powders, granules, pigments and similar products in compliance with the current USP <616> methods 1 and methods 2 as well as with EP <2.9.34>, DIN EN ISO 787-11 and ASTM B527. The instrument automatically calculates the tapped density, Hausner flowability ratio and Carr compressibility index after each test and documents the results via the integrated protocol printer.

A new noise reducing cabinet for the PT-TD300 tapped density and apparent density testing instrument is optionally available. The new cabinet reduces noise inherent to the tapping mechanism of the instrument by up to 10 decibel down to 62 decibel compared to using the instrument without a cabinet (both measured at the same distance – of 1 meter). Ten decibel is considered a noise reduction of 50% – which is an enormous noise reduction.
