The scale at which you are playing with pentane and the vessel in which you play affect the style of condenser.
If you’ve got jacketed stainless reactor, or even a an old CLS base lying around you might use one of the condensers Glacier Tanks now sell
If you’re using the boiling flask from your SPD you might find a reflux condenser on eBay that plugs right in.
Maybe start here?
