PTB 302 & PTB 502 – Tablet Hardness Testing Instrument with Integrated Report Printer PTB 302 – Manual Tablet Hardness Testing Instrument with Integrated Report Printer The digital tablet hardness testing instrument PTB 302 features an integrated report printer. It is a single force mode hardness test apparatus adjusted for linear force 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 <2.9.8> and USP <1217> Pharmacopoeia. 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). No change of tools is required; the design of the jaws does handle most kind of tablet shapes. The result is immediately displayed and printed via the integrated report 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, 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 series become one of the most sold tablet hardness testing instruments worldwide. By using an integrated report printer, the bench space requirements to of this instrument are even lower than other instruments from the PTB series, since no additional external printer is required. Furthermore, the report printer requires less paper than a standard printer and by this helps to preserve our precious natural resources.

PTB 302 & PTB 502 – Tablet Hardness Testing Instrument with Integrated Report Printer 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. Different force settings usually cause problems when comparing results received by different supplier's instruments when testing the same tablet. The hardness result is directly influenced by the contact speed and force increase rate. Faster operated test jaw means lower reproducibility and often higher...

PTB 302 & PTB 502 – Tablet Hardness Testing Instrument with Integrated Report Printer The PTB 302/502 offers a built-in calibration and validation program for the hardness test station. To validate the hardness test station the PT-MT3 magnetic tablet or different certified weights are used. Use the PT-MT to qualify the correct breakpoint detection, the PT-MT3 instrument works like a tablet, it withstands force and after “breaks”. For the two point adjustment (zero and reference) of the load cell inside the hardness station a certified reference weight of 10 kg is used. For validation...
