FYRA for End of Primary Drying Detection.  This bundle is set up to allow for vacuum drying applications like freeze-drying and vacuum ovens to help determine the end of drying. Will help you detect when most of the water or residual solvent from a product has been removed or the end of primary drying has been reached in a vacuum drying application. Background on How this FYRA End of Primary Drying package works: When a freeze dryer is equipped with both a thermal and direct measurement, these sensors can be utilized to indicate the end of primary drying (Source). Step One: Clean process documentation | Get a baseline Characterize the convection-enhanced Pirani and the capacitance manometer (in this case the DCP Quantum) against each other in a dry, empty and refrigerated system. The freeze dryer is turned on, as per the manufacturer’s operator manual, with nothing on the shelf. The shelf temperature can be left at room temperature, and if so the cold trap, the condenser, and the vacuum pump should be on and running for a period of time The vacuum oven or freeze dryer is allowed a period of time to become stable in this condition and the Pirani and capacitance manometers are read. The difference in their pressure readings in a dry, empty and refrigerated freeze dryer will be relatively small (mT to 10’s of mT) when the system is working properly. DigiVac will NOT calibrate these two gauges against each other. There may always be slight differences in their readings due to their difference in design. The difference in pressure (ΔP) between these two gauges, when dry, empty, and refrigerated, indicates how close they come together when there is little to no water vapor in the gas mix over the product. Step 2: Drying with Product The intent of primary drying is to maximize the sublimation rate within the product. As such the gases in the chamber have a high water vapor content. The Pirani sensor will read a higher pressure than the capacitance manometer. As freeze drying progresses the amount of ice converting to vapor through the sublimation process will decrease as the product becomes lyophilized from the top through the bottom of the product. Eventually, the Pirani and capacitance manometers will approach the ΔP that was established in a dry, empty and refrigerated system. Approaching this ΔP value indicates that the end of primary drying has occurred. The DigiVac FYRA controller has a rich remote command-line interface which enables the user a high degree of remote control and monitoring from any computer when communicating through the USB port. Calibrated—Every FYRA is calibrated and pretested under actual vacuum against a NIST standard (Need NIST traceable documentation? Add this option to your order) Applications—Ideal for End of Drying Detection, Freeze Drying Primary Drying Monitoring, and Vacuum Oven Drying Monitoring and Detection DCP Quantum DuoSense Measurement Range: .05 mT to 1000 Torr 275 Convection-enhanced Pirani Measurement Range: 0.1mT to 1000 Torr FYRA Bleed Vacuum Controller Components: FYRA controller Convection-enhance Pirani KF25  gauge sensor | Lesker 275, driver card, and Pirani sensor cable Quantum DCP Gauge and driver card | DuoSENS Capacitive Piezo Vacuum Sensor 0.01 to 1000 Torr, Gas Independent 3 Simple Steps for Vacuum Process Set-up with FYRA Vacuum Controller: Plumb the vacuum gauge(s) and valve into your vessel Connect the sensor, power, and I/O cables into FRYA Measure and control vacuum

Digivac Vapor Pressure Controller The DigiVac Vapor Pressure Controller is a high-end lab-grade instrument that will allow you to determine set points and maintain vacuum at that specified level. The Vapor Pressure Controller is extremely useful when trying to maintain pressure at a certain level, for example, when trying to control the vacuum level as botanical oils are processed for use in the medical industry. Key Features: USB Communication Maintain Specific Vacuum Levels 3/8" Barbed Hose Connections Digital Readout Compact Design Lab Stand Bulkhead Specifications Sensor Type Sen-775i-NPT-OEM Accuracy +/- 2 Torr Units Torr, mbar Total Range 1 – 775 Torr The Vapor Pressure Controller is DigiVac’s newest product release. This instrument has the ability to help those working in the botanical market easily process plant material through automated distillations. It both measures and maintains the pressure within rotovaps, or any type of vacuum system, following the profile created on the Vapor Pressure Profile Manager - a free, downloadable software that comes with the purchase of a VPC. 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.

J-KEM DVR-200-EV Digital Vacuum Regulator The DVR-200-EV has the same stainless steel pressure transducer inside, but the vacuum valve is outside of the controller. The value of this design is that the vacuum valve can be cleaned or replaced much easier than the valve in the classic DVR-200. Some applications, like distillations or stripping large volumes of solvent, can leave residues inside the valve which causes it to fail. Replacing the vacuum valve is the most frequent repair that J-KEM performs on the DVR-200. Replacing the valve in the classic DVR-200 is difficult and must be returned to J-KEM for repair. With the EV version, the user can disassembled the valve and wash it out, or even replace it in under 5 minutes. For large distillations or botanical applications, J-KEM recommends the DVR-200-EV. No Mercury 100% digital pressure entry and control Wetted parts are 100% stainless steel and Teflon Vacuum ramping feature eliminates bumping Resists: All organic solvents Acids Bases Water   Specifications: 100 watts. Vacuum fittings: 1/8″ NPTM. Warranty: Electronics 2 Years, Vacuum Valve 6 months (void if damaged by chemical buildup)
