Dissolution Media Degasser
Only a few minutes are required for DosaPrep®X8 to prepare medium for a dissolution test. It mixes two components, heats the mixture and degasses it.
The prepared medium can be dispensed directly into the vessels.
All parameters may be selected in a wide range with this dissolution media degasser.
Precision Pondering Cell
A precise pondering cell assures the exact mixing ratio and the precise dispensing of the prepared medium. It works gravimetrically.
A 20 µm filter in the medium/water inlet assures retaining of particles. The filter may be exchanged easily. The instrument controls the total amount of medium/water, sets it into relation with the recommended maximum value, and suggests the replacement of the filter when this maximum value is reached.
The dissolution media degasser has two inlets: one for medium or water, and one for an additive like concentrated hydrochloric acid or buffer. The mixing ratio may be varied in a wide range.
Alternatively ready prepared medium may be used.
The medium is continuously mixed with a magnetic stirrer which is electronically driven and wear free. The stirrer itself is sealed and resistant against acid. This continuous mixing results in a homogeneous medium both in respect to temperature as well as in respect to the concentration.
Precise Heating of the Medium
A specially made heater heats the medium to the desired temperature, which is continuously monitored and displayed. This helps the degassing process and saves valuable time, as the medium may be dispensed with the required temperature to the vessels. Note that the final setting of the temperature needs to be done in the menu of the dissolution media degasser.
Safety for Employees in the Laboratory
Savings of Cost and Labour
Rather than doing all the steps for the medium preparation manually the dissolution media degasser prepares the medium with all required steps automatically. Press “Start”, and the instrument will perform all steps required to obtain the desired medium.
The medium may be then dispensed directly into the medium; no further steps are necessary. Therefore it is easy to perform a dissolution test while preparing new medium. This frees the personnel from the medium preparation work and allows for other activities. Anyhow the medium preparation for e.g. 8 l takes only approx. 15 min.
