PLASTIC COATED to contain solvent in case of breakage and supplied complete with a. solvent trap available in different temperature ranges VaporNet optional accessory Vacuum pump oil or diaphragm There are several issues you need to consider when choosing your Savant SpeedVac system. Selecting the correct system is crucial for optimum performance and reliability. Thermo Scientific has a wide range of integrated and modular. 1. The solvent collection flask of the unit should always be emptied prior use to prevent accidentally mixing of incompatible chemicals. SAFETY FIRST! 2. The flask with the solution is placed on the rotary evaporator. The use of a bump trap prevents the solution from accidentally splashing into the condenser (and being contaminated). The MAXTRAP Vacuum Cold Trap from Labconco will prevent vapors from reaching and damaging your vacuum pump. This cold trap extends the lifespan of your vacuum pump by condensing liquids from harmful vapors before they can reach your pump and contaminate its oil.. The MAXTRAP Vacuum Cold Trap was designed for maximum flow, thanks to the KF-25. 1 CONTACT WIGGENS GmbH Gässlesweg 22-24, 75334 Straubenhardt, Germany Tel.: +49 7248 4529088 E-mail: [email protected] WIGGENS CHINA Room 426, Hall A, Office Building M8, No. 1 Jiuxianqiao East Road, Chaoyang. Vacuum Traps. A vacuum trap condenses vapors into another state (solid or liquid). Also called a cold trap, it protects vacuum pumps from contamination by trapping the potentially damaging vapor into its condensed form before it can be introduced into the pump (hence the name). Only the permanent gases (hydrogen, nitrogen, and carbon monoxide ....

Trap is placed between the vapor tube and the evaporation flask. This design prevent possible contamination in the event of bumping. With two 4mm drain holes at the base of the inner tube to allow solvent to drain back into the evaporation flask. Has upper outer and lower inner standard taper Related Products: Bump Trap Compare this item. Vacuum pump; One or more cold traps for solvents; Taps to switch between gas and vacuum; Tubing to connect apparatus to line; The dual manifold is the main body of the Schlenk line (Fig. 1). It has two parallel glass tubes; one connected to the inert gas supply and the other to the vacuum. Placing a cold trap at the suction of oil pump greatly lower the risk that oil vapor will backstream into the vacuum chamber. Cold traps can also be used as a condenser to separate the gases with different melting point. This is accomplished through the use of a coolant such as liquid nitrogen or a similar solvent with a low melting point.

The stainless steel solvent trap condenses vapours before they reach the pump, protecting against contamination of the oil. Fill the large, removable center well with up to 2.8L of dry ice. Savg = 3.6xQL / P. Where Savg = Average pump speed in m3/hr. QL = Leak rate Torr ltr/sec. P = System Pressure in Torr. [ You might get a doubt that, how the formula for pump capacity is derived, but there is nothing but just a unit. This kit includes the solvent trap and KF-25 vacuum fittings need to install this solvent trap onto an EV-A03 pumps (see photographs above). The solvent trap includes a manual drain valve with NPT pipe thread fittings. The solvent trap has Ebara Technologies part number C-3080-003-3200 (FT-119). Specifications: KF-25 Vacuum Flanges. Description. Dry ice / isopropanol cold trap. Provides pre-pump protection by condensing vapors. Vapors contact outside stainless steel shell, traps up to 1.5 liters condensate. Large, removable center well accommodates up to 2.8 liters of dry ice or an IPA slurry for up to 12 hours protection depending upon vapor load.
