BUCHI VAC V-513 VACUUM PUMP ROTOVAPOR SYSTEM V-800 VACUUM CONTROLLER ~ V-513P

The V-513 with the integrated Vacuum Controller V-800, create and regulate a vacuum and maintain it at a constant level by automatically compensating for any loss of vacuum in the evacuated device and returning it to the selected set pressure. This is accomplished by turning the in-tegrated PTFE diaphragm pump on and off directly. The vacuum, which is selected according to the solvent permits almost 100% condensation in the condenser of the distillation apparatus.

The integrated additional condenser assures that any solvent vapors which might have been suctioned off will be condensed out to the physical limit following the pump.

I powered this on as shown in the pictures. Green plastic covers have some spotting, see pictures. Also, note hand-print on top of V-800 controller. Produces a vacuum as shown.
