Portable Tablet Hardness Testing Instrument
PTB-M100
Portable Tablet Hardness Testing Instrument
PTB-M100 is a portable, manual hardness testing instrument for tablets. The instrument is made in strict compliance with the EP <2.9.8> and USP <1217> Pharmacopoeia. PTB-M100 is very easy to use. The force and break point are measured by a precise force sensor and the result is immediately displayed on the large color touchscreen.
Password Protection
Important settings, such as date and time are protected by a password. The password can be changed. Calibration and adjustment of the instrument also require the password.
Build Quality
The instrument is solidly built and yet perfectly portable, making it ideal for use in a production department, for example. The integrated rechargeable battery lasts for approximately two hours of operation.
Operation Principle
Touch Screen
The instrument is operated using a 3.5” color touch screen. During a test the hardness value is displayed live in either Newton (N), Kilopond (Kp) or StrongCobb (Sc). The instrument is powered by a rechargeable battery using a standard USB-C charger. The test results can be documented by connecting a ticket printer or by using the Pharma Test PT-Node network adapter. When starting a new test run, a batch number (alpha-numeric) can be entered using a software keyboard.
Manual Handling
Simply place the sample on the testing platform and manually rotate the knob. This moves the jaw and applies force to the sample. The result is immediately displayed. All results of a current measurement run are then shown in a scrollable table. Incorrectly measured samples can be discarded here. These results are still documented on the result report but are not included in the statistics. The results of the latest test run are stored in the instrument memory and can be printed repeatedly. Starting a new measurement run discards the results of the previous run.
Settings
The settings menu is password protected. This password can be changed. The instrument keeps date and time (date and time are not lost when the battery is empty) and supports 12- and 24-hour time formats and US and European date formats. All printouts contain date and time of performance and date and time of the printing.
PTB-M100 with Extended Measurement Range for Larger Samples
PTB-M100 is also available in an extended measurement range version. In this instrument variant, the mechanics have been extended to be able to test larger samples than the standard model. This is useful for certain veterinary products or other, non-pharmaceutical applications.
Measurement Ranges
PTB-M100 is available with the following extended measurement ranges:
| Part No. | Sample Min. Diameter | Sample Max. Diameter | Hardness Max. |
| 29-01660 | 30mm | 60mm | 300N |
| 29-01665 | 30mm | 60mm | 500N |
| 29-01690 | 60mm | 90mm | 300N |
| 29-01695 | 60mm | 90mm | 500N |
| 29-01620 | 90mm | 120mm | 300N |
| 29-01625 | 90mm | 120mm | 500N |
Calibration and Validation
PT-MET Mechanical Tablets
For daily verification, PTB-M100 is compatible with the Pharma Test PT-MET mechanical tablets. PT-MET are available with four different nominal hardness values (50, 100, 150, 200N). They can be purchased individually or as a complete set. They come with a certificate of calibration, operating instructions and can be returned to us for re-calibration.
PTB-CAL 15 Weight Set
Using the certified PTB-CAL15 weight set, adjustment and calibration of PTB-M100 can be carried out on site and requires only a few minutes. 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 using different traceable counterweights.
PT-Node Network Adapter for Printing and Data Transfer
PT-Node is an adapter that connects up to two Pharma Test instruments simultaneously to a network using a wired LAN connection. This way you can print test results from the instrument via your web browser on any local or network printer. Furthermore, it is possible to transfer the test results from the instruments to external systems in the same network. PT-Node supports PTB-M100.
