PTS 3E Suppository Disintegration Test Instrument

PTS 3E Suppository Disintegration Test Instrument

The instrument meets the requirements of the valid EP and German DAB pharmacopoeia. According to the Pharmacopoeia monograph 3 samples are tested at the same time. The total testing period can be pre-set within a range of 1 minute to 10 hours. When used to test suppositories the sample baskets will turn automatically each 10 minutes through 180 degrees as specified in the relevant monograph.

Test Procedure

The test basket for the three samples is placed into a 12 liter Plexiglas (Perspex) water bath. Program the total test time and turning sequence, (usually 10 minutes), and start the test. Automatically, the basket will be turned through 180 degrees in the programmed sequence during the total test time. Usually the suppository will disintegrate, within 30 minutes. If used to test Pessaries not cycling time is entered but the samples are placed on top of the basket which is covered by the supplied glass plate. A built-in thermostatically controlled heater warms the water within the bath to 37°C or the required temperature. A 1000W heater and a powerful pump circulates the water within the system. The heating system is specifically designed to protect it against the entry of any fat or active materials. In order to clean the system, the bath, the sample holder and the sample baskets can be completely removed from the instrument.
