Vibration elimination for disolution
testers
Pharma Test introduced vibrationally decoupled baths some years ago, and has now introduced special Vibroban shock absorbing feet to virtually eliminate the impact of environmental vibration sources
How often have people failed their dissolution calibrator tests on one or two vessels only? Everything seems to be in order, but there are those one or two cases where there is just something wrong and there's no real reason Well, perhaps there is a reason but nobody can see it

Compact concept in dissolution testers
All components are assembled in one unit to provide a total solution to the analysis of solid dosage form dissolution profiles, while still maintaining full USP/EP specifications
Dissolution de-aeration unit saves time and money
The DDS-4 allows users to prepare demineralised water or buffered medium, ready to use at 37C, all they do is point and pull to dose the medium into the dissolution vessels and then start the test
Vibration is one of the biggest offenders in the failed dissolution test camp.
We all take precautions to make sure that the drive belts for the dissolution tools are in good condition and lubricated so as not to 'squeak' and send high frequency oscillations down the tool shaft.
We all make sure that the bearings are in good shape and don't generate any excess noise and wobble; but what about the lab? What about the fridges or the Bet instrument, those HPLC pumps or air conditioning systems.
All of these installations generate noise and vibration.
At certain points around the lab, they become focused or are transmitted through the bench.
Pharma Test has developed an answer to this problem of environmental vibration.
It already introduced vibrationally decoupled baths some years ago (ie, the bath is on a separate platform to the tester itself).
It has now introduced special Vibroban shock absorbing feet to virtually eliminate the impact of environmental vibration sources.
This is especially important in the current climate of proposed tighter OQ specifications which will inevitably will include minimum vibration levels.
This is said to be the only instrument system to use this type of vibration suppression.
