The Manual Tablet Testing Instrument
PTB 311E
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 and the diameter, height station.
Test Thickness, Diameter or Length and Hardness of the same Tablet using just one
Instrument, the PTB 311E. The instrument is made in strict compliance with the EP <2.9.8>
and USP <1217> Pharmacopoeia.
Enter the nominal test information for Thickness, Diameter or Length and Hardness via the
PTB 311E keyboard. Select the unit to measure, mm - IN - kp, N or Sc, now place the
sample upright into the Thickness Test Holder and start the test. The driven jaw will now run
forward and touch the tablets highest point to measure the thickness, thereafter it reverses
back so that the sample falls into horizontal position to test diameter and hardness.
The 3 results are immediately displayed and printed to a connected Dot-Matrix or suitable
PCL Type Laser- or DeskJet printer. Repeat this until your series has been tested, get a full
print including each individual result, mean value and deviations.
In case you need to test hardness “only”, no problem; zero Thickness and Diameter station
and do hardness test only. This flexibility and the reproducibility of the results have made the
PTB311E series to become one of the most sold hardness testers.
Operating Principle…
Even in the existing monographs from USP and EP is no standard force setting or force
increase mode established. This usually is causing problems comparing results received of
different suppliers instruments of the same tablet. The hardness result is directly influenced
