SPE vacuum pump

[pueblito]

Dear chromatographers.

Recently We have purchased a SPE manifold in order to do some clean up for environmental applications, principally PCBs, PAHs, Organochlorine, etc.
So, We are looking for a cheap rugged oil free vacuum pump for SPE applications, any suggestions?

thank you.

I recommend the Rocker400.

I'd say that besides diphragm pumps, a simple water jet vacuum pump can be a solution. And it is highly reliable!

Thanks for your help guys.

A water jet vacuum pump, it´s an interesting alternative.
