Worth knowing before you order
A rough-vacuum, oil-free pump: 11 L/min, with the vacuum figure printed as ≥ 0.075 MPa against a row headed maximum, which reads oddly and is worth confirming as a gauge value on the quotation. It suits filtration, SPE manifolds and blow-down work, not freeze-drying or vacuum distillation. The catalogue does not claim chemical resistance for the diaphragm, so for solvent-laden or corrosive vapour specify the two-stage PTFE-coated pump instead. Supplied with a connecting tube only - no trap, gauge or exhaust filter.Specification
