distributor block and two RVCs
With two RVC 2-18 CD

HCl and a cooling trap with distributor block
and 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 vacuum pump is connected to the distributor block. An electromagnetic
stop valve is connected to each of the RVCs. The distributor block includes
an aeration valve. It ensures the aeration and facilitates the removal of the
glass cooling trap.
The method is suitable for aqueous and solvent-containing samples.
