- Page 3 The VPC facilitates separating chemicals that have vapor pressures as close as 10 Torr to one another. It can also be used to prevent bumping by gradually changing the pressure. The VPC can also help save your pump, widen the choices of pumps you can use for low temperature distillation, and keep vacuum pump oil out of your system.

Page 6: Calibration Procedure
The VPC valve is a bit noisy, but more of a finger tapping loudness. If you hear a loud metallic sound, then something is wrong. Consult your vendor. (J)D □ 1020 Campus Drive West, Morganville, NJ 07751 - Office: 732-765-0900 igiVac Fax: 732-765-1800 - sales@digivac.com - www.digivac.com... -

Notes on calibration There is inherent drift in all sensors including the DigiVac 775i piezo resistive sensor. Drift is specified in the datasheet, but the specification is typically a worst case scenario as drift is not easily predicted and depends on operating environment. Depending on your accuracy requirements, it makes sense to set up a calibration interval to obtain as found data, and get a fresh calibration. - Page 8 1/8" FNPT (if you remove the nipple), 1/8"MNPT, 1/4" ID hose with a barb, 3/8” ID hose fits over the nipple LED Heights .56” .35” (J)D □ 1020 Campus Drive West, Morganville, NJ 07751 - Office: 732-765-0900 igiVac Fax: 732-765-1800 - sales@digivac.com - www.digivac.com...
