Digital Pressure Regulator and Netbook controller · Catalog# DPR-1100
$3,145.00

Precise regulation of ±0.1 torr of volumes as small as 1 mL


0.1 Torr Regulation No Mercury



  • Presision, multi-stage vacuum distillations

  • Automatically compensates for leaks in the equipment under test

  • Maintains constant precise pressure, even in systems with a continuous gas purge

  • Twelve step pressure ramps

  • Customizable

    • Add temperature or pressure channels

    • Custom programming for unique applications

    • Define output events based on time, temperature or pressure




J-KEM's vacuum and pressure regulators maintain pressure to 0.1 torr in reactors and equipment with volumes as small as 1 mL.  Built from J-KEM's Infinity Controller, these instruments can be customized to automate virtually any laboratory or quality control task involving the regulation of vacuum or pressure.  For applications requiring both evacuations and repressurization, a Back-Fill option is available for the DVR-1000.  The DVR-1000 regulates vacuums, the DPR-1100 regulates positive pressures, and the DDR-1200 regulates both vacuum and positive pressures.


KEM-Torr software (included) displays a real-time plot of system pressure, implements a 16-step pressure ramp, data logging and remote PC control. Custom features can often be added at no additional charge.


Requires the selection of a proportioning valve

Digital Pressure Regulator · Catalog# DPR-1100-PC
$2,795.00
Same as DPR-1100, but without Netbook PC controller. Includes KEM-Torr software to load on your PC.
Regulation of positive pressures in the range of 0 psi (atm pressure) to 50 psi.
The maximum pressure of the controller is user selectable.
Replace the ‘#’ in ‘DPR-1100-#’ with the desired maximum pressure. Ranges: 1, 5, 15, 30, 50 psi.
Requires the selection of one PSV valve.
Gage transducer is standard, but absolute is available on request. Learn More

Digital Vacuum Regulator ∙ 120 Vac ∙ Catalog# DVR-200
$1,365.00

An ideal instrument for laboratory vacuum regulation. 


Connect the regulator to any vacuum pump or vacuum source and then to any piece of equipment to regulate pressure in most cases to ± 1 torr. 


A pressure ramp feature evacuates equipment at a user defined rate to eliminate bumping due to solvent degassing or over-evacuation. 


The vacuum regulator is ideally suited for large volume distillations, rotary evaporators and vacuum chambers. 


Recover > 99% of solvent from rotary evaporators


Features:


NO Mercury


100% digital pressure entry and control


Wetted parts are 100% stainless steel and Teflon


Vacuum ramping feature eliminates bumping


USB port and free software for PC control


Resists: All organic solvents Acids Bases Water


Not recommended for small volume distillations or applications which involve a continuous purge with gas, these applications are better performed by J-KEM’s Precision Vacuum Regulator, Model DVR-1000.


Two Styles of Regulators to Choose From


Model DVR-200


Designed for continuous vacuum sources, such as oil-filled vacuum pumps, aspirators, or systems that are “always on”, like in-house vacuum systems. The DVR-200 regulates pressure by opening and closing a valve that separates the vacuum source from the system being evacuated. In most cases, the DVR-200 is the best choice.


Model DVR-280


Designed for use with diaphragm vacuum pumps that regulate pressure by turning the pump On and Off. The DVR-280 doubles the life of diaphragm pumps by starting the pump at atmospheric pressure before connecting it to the vacuum system.
