Tablet breaking force (commonly called hardness) is a crucial characteristic in the manufacturing of solid dose formulations, affecting bonding and integrity of the final form, and its ability to withstand the stresses of production, packaging, and transportation. An incorrect degree of hardness further affects the dissolution properties of the tablet, potentially causing it to release active pharmaceutical ingredients too quickly or too slowly. Accurate evaluation of hardness is essential to tablet product development, manufacturing, and quality control.

Available models

T-Series (HC6.2) testers provide accurate measurement of tablet length, diameter and breaking force (hardness) in a compact space with an easy-to-use interface able to operate with or without gloves. EXT models allow an external Mitutoyo thickness gage. Up to 99 products are managed though an external USB device or optional integrated memory. Test results can be sent to an external printer connected to a USB port.

  • User-friendly 7-segment display with buttons
  • Integrated LED status light
  • EXT+ model accommodates external scale
  • Units of measure: N/Kp/SC
  • Range: 4 – 400 N accurate to ± 1 N
  • Quick and simple calibration with reporting

H-Series testers measure length, hardness, and up to three additional parameters, depending on the model. The intuitive touch screen makes it very easy to select products and view test results. Rounded corners and smooth surfaces provide easy cleanup. Calibration interval is automatically monitored. Higher models allow connection of external scale or thickness gage.

  • Internal management of up to 10,000 products
  • User access control
  • Constant force and constant speed
  • Breaking force: 4 – 400 N accurate to ± 1 N
  • Sensor supported menu navigation
  • Graph view during test
  • LIMS interface (XML file)
  • Validation documents IQ/OQ

The P-Series models with Vibralign (P3+, P4+, and P5) provide the ability to measure 3, 4, or 5 parameters for up to 20 tablets automatically. The 7-inch touch screen makes test setup fast and easy. Lab productivity is further enhanced by full network integration, no limit on user accounts, and the ability to configure user groups with different levels of access. The integrated 360 degree LED status display is visible from a distance.

  • Manage up to 10,000 products internally
  • Constant force and constant speed; breaking force 4 – 400 N accurate to ±1 N
  • Sensor-supported menu navigation
  • Graph view during test; automatic PDF export to USB stick; LIMS interface(XML file)
  • Smooth surfaces easy to clean
