PTG-M100
Manual Powder Flowability and Angle of Repose Tester
The Pharma-Test PTG-M100 is a high-precision manual powder flowability and angle of repose tester designed for pharmaceutical and industrial laboratories. It provides reliable measurements of powder flow characteristics — key parameters in powder processing, formulation development, and quality control. This instrument ensures testing in full compliance with recognized international standards, including USP <1174>, EP <2.9.36>, EP <2.9.16> and ISO 4324.
This user-friendly and durable analyzer allows measurement of both flow time and angle of repose using the same setup, making it an essential tool for characterizing granules and powders during formulation and production.
Key Features
• Standards-Compliant Testing
Fully conforms with USP <1174>, EP <2.9.36>, EP <2.9.16> and ISO 4324 (12/83) requirements for powder flow and angle of repose testing.
• Dual Functionality
Performs both angle of repose and flowability (flow time) measurements using a single instrument design.
• Angle of Repose Measurement
The instrument forms a free-standing powder cone on a 100 mm dish. The included digital height gauge accurately measures cone height, enabling the calculation of the angle of repose.
• Flowability / Flow Time Testing
Flow time is measured by timing the passage of a 100 g sample through a funnel with a specified nozzle opening, using an external stopwatch and analytical balance (not included).
• Adjustable Design
The conical funnel and optional manual stirrer can be adjusted vertically and locked in place without tools, enhancing ease of use with powders of varying flow properties.
• Stable and Easy Setup
A robust base plate with integrated spirit level and adjustable leveling screws ensures proper alignment and reproducible results.
