Vacuum Leak Tester VDT/S
Brand: Erweka | Category: Scientific & Laboratory Equipment
The VDT/S tests blisters and other packaging forms for leaks. Maximum vacuum, with an absolute pressure range up to 100 mbar, and the vacuum hold time before release are set from the symbol keypad, while the actual vacuum is shown continuously on the LED display. To check density the instrument runs a methylene blue dye test split into several phases: during pressure maintenance the blisters are exposed to a vacuum generated in the vacuum container, the container is then ventilated, and in the penetration process the blister rests in the methylene blue solution so the solution can be drawn into any imperfectly sealed packaging. Test run parameters such as actual and set vacuum value and hold time are documented through a USB interface or a connected printer, and the integrated vacuum pump can be recalibrated with the optional validation kit containing a type DVR vacuum meter.

- Suppository Penetration Tester PM 30
The PM 30 measures the softening time of suppositories, which must disintegrate, dissolve or melt at body temperature for their active ingredients to be released. Erweka offer a version for EP method A and for method B: the PM 30 penetration tester is Apparatus A according to EP and the PM 3 is Apparatus B. Both were developed to give reproducible measurements of softening time at specified temperatures, and the design of the test device makes visual observation of melting characteristics straightforward. The unit consists of three test stations.
- Tapped Density Tester SVM II
The SVM II is Erweka's latest generation tapped density tester. Its 7 inch high resolution touch display keeps the operator focused on 100 % USP / EP compliant tapped density testing, and TestAssist automatic calculation walks the user through the process while working out the Hausner Ratio and compressibility index and printing a report after every test. A newly designed SwitchPlate system produces five versions of the instrument, covering USP 1, USP 2 or USP 3 in one or two test station configurations or a combination of both methods, and the user can change from one variant to another within minutes. Supported methods run from USP 1 and USP 2 through to ASTM B527-15 and DIN EN ISO 787-11:1995.
- Suppository Hardness Tester SBT 2
The SBT 2 suppository hardness tester is built around an electrically heated chamber with an integrated sample holder and a set of interchangeable plastic inserts that hold suppositories of different sizes. Once the desired temperature is reached, hardness is tested using weights supplied as standard, which are placed on the device one after another until the suppository collapses under the load. Results are expressed as the total weight required to collapse the suppository.
