MAXTRAP105 -105°C Vacuum Cold Trap, 120V       Cascade’s MAXTRAP105 is not an ordinary lab-grade cold trap. Cascade has integrated  features necessary for time-sensitive, high-throughput, production-focused vacuum purging or drying applications.   MAXTRAP105 Cold Trap Includes:   Cascade’s COLDWELL 304 Stainless Steel Trap Insert (Patent pending baffle system)   3 Quart Capacity (2839 ml)   Viton Gasket for Vacuum Integrity   Labconco -105°C Refrigerated Base   Green CFC / HFC Free Refrigerants   Power Cord   3mm Neoprene Insulator Cap   Requires 800ml (~ 3.5 cups) of a transfer fluid such as ethanol. Not Included. Cascade recommends: ethanol, glycol, cryo-cool fluids   Quality Made in USA   1 Year Warranty   Connection Lines and hardware: 4′ of 1″ Diameter Vacuum Tubing with KF-25 Flanges on each side. KF-25 clamps, centering rings for the connection tube     MAXTRAP Tips: Safety   At very cold temperatures, solvents and even oxygen can re-condense back into liquid. This is potentially explosive. Liquid oxygen is a light blue color and can condense into a cold trap if a pump has sucked air through the trap when the trap is very cold. Always follow your standard operating procedures and safety guidelines.   Don’t Stop: Keep Processing while trap is being reclaimed, cleaned, refreshed   Cold traps can become full or the captured material freezes and blocks flow. For high moisture, outgassing, 24 hour processing/vacuum purging consider adding a second, spare COLDWELL trap. The secondary COLDWELL can be dropped into place so processing continues while the full trap is cleaned, defrosted.   Quick Start Up Tips: Remove shipping foam from reservoir bottom prior to use   Fill reservoir with 800ml (+/-3.5 cups) ethanol to marked line   Monitor ethanol levels inside reservoir   Allow at least 30 mins for trap to cool   Keep side vents clear. Allow at least 4″ for airflow   Monitor interior of stainless trap for clogging   Short tube – attach to vacuum pump   Tall tube – attach to vacuum oven   MAXTRAP105 Differences:   The key to quality cold trap performance is: time, surface area, and temperature. Time: Most cold traps have very narrow inlets and outlets, slowing down your process. Not Cascade’s MAXTRAP105! Full KF25 inlet and outlet connections never reduce flow. Surface Area: Most cold traps have glass or a smaller surface area to collect the matter your vacuum pump would otherwise ingest.

 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.
