Use Model 2019 for vacuum filtration, desiccation, degassing, and other mid-range vacuum applications.Recommended for operations utilizing organic / aqueous solvents and or light acid / base (e.g. acetic acid) solutions. Ideal for single funnel vacuum filtrations, SPE manifolds, or up to 6 holder manifold filtrations.FeaturesPTFE Contact SurfacesLight and PortableApplicationsVacuum Filtration Many filtrations require only minimal vacuum to proceed; deep vacuum is not required. Vacuum pump flow required is roughly proportional to the total surface area of filters being used. Filtration of particulate-clogging samples can be improved somewhat with deeper vacuum, but a combination of larger filter surface area, smaller samples, and sequential use of decreasing porosity filter papers may also be required for timely filtration. Choose a standard duty vacuum pump for aqueous vapors; use a PTFE pump for resistance to harsh chemicals.Free air flow 37L/min; Maximum vacuum 24" Hg. Pump can also be used to pressurize up to 18 PSIG. Comes standard with 115V line cord and convenient power switch.
