Manual 3-in-1 Tablet Testing Instrument
The manual tablet testing instrument PTB 311E/511E/311E-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 thickness, diameter or length and hardness as well as a batch number via the PTB 311E/511E/311E-800 keyboard. Select the units to measure, mm – Inch, KP (Kilopond), N (Newton) or Sc (Strong Cobb). Now place the sample onto the sample upright in to the Thickness Jaw and start the test. The driven jaw will run forward, touch and force the tablet at its highest point to measure the thickness, thereafter it reverses back so that the sample falls into horizontal position to test its diameter (length) and immediately its hardness (tablet breaking force). The 3 result are immediately displayed and printed to a connected dot-matrix or suitable PCL5 type laser- or Deskjet 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. In case you need to test hardness “only”, no problem; zero Thickness and Diameter station and perform hardness tests only. This flexibility and the reproducibility of the results have made the PTB 311E/511E/311E-800 series to become one of the most sold hardness testers.
