Manual Tablet Hardness Testing Instrument The manual tablet hardness testing instrument PTB111E / 111E-500 / 111E-800 is a dual force mode hardness test apparatus as it can be used for either linear force or linear speed increase while tablet hardness is tested. It offers a multiple point validation procedure for the built-in digital load cell. The instrument is made in strict compliance with the EP and USP Pharmacopoeia. Test Procedure Enter the nominal test information for hardness as well as a batch number via the PTB111E / 111E-500 / 111E-800 keyboard. Select the unit to measure, KP (Kilopond), N (Newton) or Sc (Strong Cobb), now place the sample onto the sample dish and start the test. The driven jaw will run forward, touch and force the tablet until it breaks to measure the hardness (tablet breaking force). The result is immediately displayed and printed to a connected dot-matrix or suitable PCL5 type laser- or printer. Repeat this until your series has been tested, get a full print-out including each individual result, date, time, serial number of the instrument, batch number of the product tested, mean value and deviations of the test series. The flexibility and the reproducibility of the results have made this and other models, like the PTB 311E/511E/311E-800 series become one of the most sold tablet hardness testing instruments worldwide. Operating Principle Even in the existing USP and EP monographs there is no standard force setting or force increase mode established, but it is recommended to use a linear force increase rate of 20N/s.
