DigiVac Vapor Pressure Controller
$2,300.00
In stockDigiVac Vapor Pressure Controller (VPC-M), a vacuum measurement and regulation instrument for chemistry distillation and rotary evaporation. It holds a user-set vacuum set-point and shows both set-point and current pressure on an LED readout, resolving separations of compounds whose vapour pressures differ by as little as 10 Torr. UL, CE, CSA and RoHS certified, with bench-top or lab-pole mounting.

Description
Digivac Vapor Pressure Controller
The DigiVac Vapor Pressure Controller (VPC), is a rugged, modern vacuum measurement and control instrument designed to make vacuum measurement and regulation easy through the use of a simple LED readout and large tactile buttons. Electronically, it is a highly accurate digital vacuum gauge utilizing field-proven isolated vacuum sensor technology coupled with reliable valve and plumbing parts. This regulator was specifically designed for chemistry distillations that can be aided by precise pressure control. 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.
The DigiVac Vapor Pressure Controller allows you to determine set-points and maintain vacuum at that level. The vacuum regulator is particularly useful when you are looking to maintain pressure at a certain level as needed for botanical processing and rotary evaporation or ideal for any vacuum process that involves vapors. Mounting can be bench-top or on a laboratory pole.
• Display of both the set-point and current vacuum control• Fine control of target vapor pressure for more precise compound separation through distillation• Flow path designed to be tolerant of harsh chemicals• UL, CE, CSA and RoHS Certified, Fully safety certified for USA, Canada and Europe
Easy to use and operate, the VPC has just four ports/plug ins on the back of the unit-USB Communication-Power Jack-Hose Barb for Vessel, Flask, or Tank-Hose Barb for Vacuum Pump
The front of the gauge is similar in terms of being straightforward. It has displays of both your current vacuum and chosen setpoint, as well as a numerical up/down control, regulation button, and power switch. Just hook your Vacuum Pump to one side, the Rotovap to the other side and plug it in. If you’d like specific ramp rates and time duration, then install the free software, hook up the USB to connect the unit to the computer hosting the software and you can set up your process profile. The vacuum system is what you are going to regulate, an example being your Rotovap, vessel, flask or vacuum oven. Once the unit is set up and regulating, the process can also be observed within the software, thus telling you how your system and pump are performing.

Frequently asked questions
What is supplied in the box?+
One DigiVac VPC-M, one AC/DC desktop power adapter with power cord, two pole clamps and handles, one 3 ft USB to mini-USB cable, two 201 stainless steel worm clamps (5/8 in to 1 in clamp ID) and one quick start guide.
How is the VPC plumbed into a system?+
There are four connections on the rear: USB communication, power jack, a hose barb for the vessel, flask or tank, and a hose barb for the vacuum pump. The vacuum pump goes on one side and the system to be regulated - rotary evaporator, vessel, flask or vacuum oven - on the other. Mounting is bench-top or on a laboratory pole.
What control does it give over a distillation?+
The front panel shows current vacuum and chosen set-point together, with numerical up/down control, a regulation button and a power switch. The listing states the VPC can separate chemicals with vapour pressures as close as 10 Torr to one another, and that gradually changing pressure helps prevent bumping.
Can the process be programmed or logged?+
Yes. Connect the unit to a computer over USB and use DigiVac's free software to set ramp rates and step durations as a process profile. The same software lets you observe the process while it runs, which is how you see whether the pump and system are keeping up.
What certifications does it hold?+
The listing states UL, CE, CSA and RoHS certification. We restate the manufacturer's certification list only; CASRAI does not itself certify the instrument.
Is the flow path suitable for aggressive solvents?+
The listing describes the flow path as designed to be tolerant of harsh chemicals, but gives no wetted-material list. If you are running an aggressive solvent, confirm the wetted materials with DigiVac for model VPC-M before ordering rather than relying on that general statement.
