JKEM DVR-200 Digital Vacuum Regulator is a precision instrument designed for laboratory applications requiring continuous vacuum regulation. Ideal for use with oil-filled vacuum pumps, aspirators, or in-house vacuum systems, this digital vacuum regulator provides reliable pressure control by automatically adjusting the valve to maintain the desired vacuum level. Its advanced features make it the perfect choice for large volume distillations, rotary evaporators, and vacuum chambers, where accurate and stable pressure is critical.

Key Features:

• Mercury-Free Design: No mercury used, making it safe and environmentally friendly.
• 100% Digital Control: Fully digital pressure entry and control for accurate and easy settings.
• Durable Wetted Parts: Made with stainless steel and Teflon for resistance to organic solvents, acids, bases, and water.
• Vacuum Ramping: The vacuum ramp feature allows for controlled evacuation, eliminating bumping during solvent degassing or over-evacuation.
• USB Control: Comes with a USB port and free software for PC control, enabling easy integration and remote operation.
• Ready for Use: Includes 3/8" hose barb connectors and a mounting bracket for quick installation.

Ideal Applications:

• Rotary Evaporators: The DVR-200 is perfectly suited for rotary evaporators, allowing users to easily set and maintain the required vacuum levels during solvent evaporation.
• Large Volume Distillations and Vacuum Chambers: Ensures consistent pressure control for efficient distillation and vacuum processes.

Usage with Rotary Evaporators:

• Simple Operation: Set the regulator to the appropriate pressure, move the switch to the METER position to evacuate, and switch to FULL VACUUM for the final solvent removal.
• Continuous Pump Operation: The vacuum pump can run continuously, with no need to adjust the set-point pressure, streamlining the distillation process and improving efficiency.

Specifications:

• Vacuum Regulation Range: Typically regulates pressure down to 1 torr.
• Vacuum Requirements: The regulator functions effectively with various vacuum sources as long as the vacuum source pressure is lower than the desired system pressure.
• Materials: Wetted parts made of stainless steel and Teflon for durability and compatibility with aggressive solvents.

The JKEM DVR-200 Digital Vacuum Regulator offers an advanced solution for laboratories requiring precise and reliable vacuum regulation. With its easy-to-use features, durable construction, and compatibility with rotary evaporators, it ensures efficient and effective solvent removal in a variety of applications.
