Suppository Testers

The suppository hardness tester (type SBT 2) consists of an electrically heated chamber with an integrated sample holder and a series of interchangeable plastic inserts for holding suppositories of different sizes.

Once the desired temperature is reached, the hardness is tested using weights ( included as standard) which are gradually placed on the device until the suppository collapses under the load of the added weights. The results are expressed in terms of the total weight required to collapse the suppository.

The ERWEKA suppository disintegration tester ST 35 comes with three turnable test stations, each located in a four-liter glass vessel with optional magnetic stirrer. The device also contains a thermostatically heated water bath (leak-proof and double-secured) in which the test stations are placed.

The test stations are automatically turned by 180° at adjustable intervals. The ST 35 features an integrated high-performance flow-through heating system (accuracy ± 0.2° C) and an internal temperature sensor for temperature display.

The test time and set bath temperature are conveniently entered using the membrane keys. The current test time and the current water temperature are displayed on clearly visible red LEDs. If desired, an alarm can be selected which sounds after the set test time has elapsed.

Thanks to the width of the ST 35, the test stations can be easily separated from each other to make cleaning easier. Optionally, separately controllable magnetic stirrers can be placed in each test station (glass beaker) to achieve the desired hydrodynamics.
