STANDARD: Condensation of the vapours in a glass cooling trap
With a Rotational Vacuum Concentrator 2-18 CDplus HCl, a cooling
trap and a glass cooling trap
The characteristic feature of a rotational vacuum concentrator (RVC) is the
combination of vacuum and rotation. During the process, a gas volume is
released. The released vapours that are carried off by the RVC condenser
in the glass cooling trap. This glass cooling trap is located inside a CT 02-
50 SR or CT 04-50 SR cooling trap.
The method is suitable for aqueous and solvent-containing samples. The
RVC, cooling trap, and vacuum pump are connected with each other. The
electromagnetic stop valve is also connected to the RVC and its connector
is plugged into the "stop valve" socket.
An aeration valve can be installed between the vacuum pump and cooling
trap. It ensures the aeration, and facilitates the removal of the glass cooling
trap.
