This the area for manual and semi-automated tablet hardness testing instruments. Click on the images for more information about performance, accessoires, calibration tools and consumables.
Tablet hardness testing is used to test the breaking point and structural integrity of a tablet under conditions of storage, transportation, and handling before usage. All Pharma Test tablet hardness testing instruments meet the latest requirements of the USP monograph <1217> and EP <2.9.8>.
A note on calibration: The current USP Pharmacopeia requires the force sensor of a tablet hardness testing instrument to be calibrated periodically over the complete measuring range (or the range used for measuring samples) with a precision of 1N. All Pharma Test tablet hardness testing instrument can be statically calibrated over the complete measuring range by the use of different tracebale counterweights. All instruments support the checking of at least three different points during calibration to prove the linearity of the force sensor. Furthermore, Pharma Test offers the PT-MT magnetic tablets to calibrate the breakpoint detection of the whole tablet hardness testing instrument (force sensor and mechanics of the instrument). All Pharma Test tablet hardness testing instruments are fully compliant to the requirements of the current USP Pharmacopeia.
All Pharma Test tablet hardness testing instruments are fully USP <1217> and EP <2.9.8> compliant
Hardness only and „3 in 1“ instruments are available
Ampoule breakpoint testing solutions available
PT-MT3 provides and independant means of qualification
PTB 420, Automated Hardness Test Instrument with Balance Connection
The automated tablet testing instrument PTB 420 is a dual test mode instrument to determine the diameter, thickness and hardness of tablets. Prior to testing the hardness of the tablet the PTB 420 can measure sample thickness (or height) and diameter (or length). The thickness is detected automatically by an optical system.
PTB-M, Portable Hardness Test Instrument
PTB-M is a manual, portable hardness testing instrument for tablets. PTB-M is very easy to use. Simply place the sample on the testing platform and rotate the knob manually.
The PTB 111E is a standard hardness testing instrument to be used in tabletting departments and everywhere where only hardness test data is required. The PTB 111E is equipped with a printer and communication port. » more information
