CALEVA BioDis
Dissolution Tester with 6, 7 or 8 rows
The CALEVA RRT 10 is the perfect unit for
multiple media change and complies with USP
apparatus 3 and method 7 (optionally
switchable without the need of tools, within
approx. 1 minute). It is the perfect solution for
multiple pH change due to the 6, 7 or 8 rows of
vessels, 6 test stations and 2 reference posi-
tions or 7 test stations (optionally) each. The
vessels are located in a heated water bath
which is heated by an external heating system.
The unique left to right movement allows easy
access and visibility to each row. Additionally
there is no software or head unit to attract cor-
rosion.
The RRT 10 is operated by a removable touch-
screen. Media loss by evaporation is prevented
by an automated covering system.
Optionally a sampling station for automation is
available.
 6, 7 or 8 rows, each with 6 stations and 2
vials for reference purposes, optionally 7
test-stations of the same capacity
