Agilent IDP-3 Dry Scroll Vacuum Pump With Inlet Isolation Valve
Agilent IDP-3 Dry Scroll Vacuum Pump With Inlet Isolation Valve A Overview The Agilent IDP-3 dry scroll pump is an innovative, compact, high-performance, oil-free vacuum pump that is suitable for a wide variety of applications. It is the smallest scroll pump made for general vacuum applications, which makes it easy to integrate into OEM systems, and it weighs only 21 pounds (9.5 kg). Yet with a pumping speed of 2.1 cfm (60 L/min) and a very low base pressure of 250 milliTorr, it is the highest-performing dry pump in its class. Agilent IDP dry scroll pumps are oil-free, compact, quiet, high performance vacuum pumps. IDP pumps use a single-sided scroll design that allows for a straightforward 15 minute maintenance procedure with simple tools. Large pumping speeds and compact sizes are ideal for many applications in the research, analytical instrument, and laboratory markets. IDP pumps are hermetic, with the motor and all bearings completely isolated from the vacuum path. This design extends the bearing life and provides clean, dry vacuum to the application. An inlet isolation valve is available as an integral option that adds no additional height to the pump. The IDP-10 uses an inverter driven motor, which provides uniform vacuum performance at all global frequencies and input voltages. Its uniform global performance and compact size make it an ideal choice for analytical instruments and industrial OEMs. Specifications Base pressure (50 Hz) - Torr & mbar 2.5 x 10-1 Torr 3.3 x 10-1 mbar Base pressure (60 Hz) - Torr & mbar 2.5 x 10-1 Torr 3.3 x 10-1 mbar Dimensions (WxHxL) 5.5 in x 7.13 in x 14.09 in Exhaust Connection ¼ inch female NPT (10 mm hose barb provided) Height 7.13 in Inlet Connection NW16 Input Voltage 1Ø, 115 V. 60 Hz Length 14.09 in Noise Level 55 dB(A) Pumping Speed (50 Hz) 1.8 CFM 3 m3/h 50 L/min Pumping Speed (60 Hz) 2.1 CFM 3.6 m3/h 60 L/min UNSPSC Code 40151502 Width 5.5 in

BVV 6" Falling Film Evaporator
BVV 6" Falling Film Evaporator Cutsheet Is your lab floor filled with a fleet of rotary evaporators? Looking to increase solvent recovery throughput? Our new and compact 20GPH Falling Film Evaporator (FFE) has the capability to maximize throughput and replace up to five 50L Rotary Evaporators. The BVV™ 20GPH Falling Film Evaporator is designed to evaporate ethanol that has been diluted in crude oil during a filtration or extraction process. By reducing the vapor pressure inside the system and metering the injection valve, the user can set the heat exchangers to the appropriate temperatures to efficiently evaporate solvent from their crude oil. We paired our FFE with reliable equipment that will keep operations running. End users are required to plumb the process inlet and outlet connections for both heat exchangers. They are supplied with 1.5” sanitary tri-clamp connections. BVV™ can assist with necessary parts needed for a permanent or temporary installation. Temporary installations may be necessary if your lab has limited fume hoods or space which is shared with other processing equipment. Below you will find key features, additional equipment included with the system and the power requirements for each, and real-life efficiencies that were tested. Key Features: · Compact rack design for use in fume hoods (39”x30”x75.5”) · Vernier scale metering valve for controlled injection · Accurate heater and chiller temperature control · Deep vacuum for effective solvent removal · Discharge pumps to eliminate constant reservoir draining and down time · Chemical resistant vacuum pump · Adaptable discharge outlets to customer preference · Insulation to limit thermal loses and reduce condensation (Not Pictured) · Sanitary tri-clamp and compression fittings · Pre-heat injection coil · Injection distribution plate · Tube in shell heat exchanger for efficient evaporation and condensation · Packable vapor path for reduction of contaminants and cleaner separation · Water reservoir for priming the heating system and expansion during operation Crude Discharge Pump Easily control discharge speed and collect your extract directly from the 3/8" tube via a collection vessel or swage on a fitting of your preference to pump collected extract to a secondary location. Eliminate constant reservoir draining and operate continuously. Metered Solvent Injection Effectively repeat efficiency and throughput with our vernier scale metering valve. Easy to dial in the desired efficiency and throughput desired by the user. Distribution Plate Directs the injected solvent to be evenly distributed across all tubes in the heat exchanger which maximizes the effective heating surface area. Solvent Discharge and Vacuum Pump The solvent discharge pump eliminates the need for a reservoir and allows you to pump recovered solvent to any desired secondary location. The vacuum pump manifold gives you easy vacuum control during the complete operation. POWER REQUIREMENTS The equipment listed below is included with the system.
