JKEM model DVR-1000 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.
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. The DVR-1000 communicates via a standard 9-pin connector using an RS232 protocol, this allows communication with the controller using a standard PC comm port.
