About 2019B-01 - Chemical Duty Vacuum Filtration Pump

Welch, 2019B-01, Diaphragm Pump - Vacuum Filtration with North America Plug 115V Economical Model 2019 diaphragm vacuum pump is durable and chemical resistant. 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. Features PTFE Contact Surfaces Light and Portable Applications Vacuum 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.
