$25 Philips Medical Systems PMTs from Sphere Research

Low-Cost Scintillation Probe Based on a Surplus XP3312 PMT for Ludlum Ratemeters www.diyPhysics.com prutchiSphere Research is clearing out all the Philips PMT assemblies they have in stock to empty their expensive off-site rental storage space. While stock is available, you can order any PMT shown as a Philips Medical Systems assembly at the beginning of this page for only $25 +shipping:


Simply identify the deal as coming from DIY Physics when ordering (Note from diyPhysics.com: nothing in it for us except passing along some great info…).

All these tubes will be cleared out shortly so they can close down their over-priced off-site rental storage space. The offer is limited to stock on hand at the time of order. Sphere Research is happy to consolidate orders and help you minimize shipping costs wherever possible.  They can take Visa, MasterCard and PayPal for orders. These are very high performance tubes and hard to find, but they are very awkward for them to store in the big factory boxes, so they have to go.

    Very interesting projects!
    It is good that you suggest a source for surplus photomultiplier tubes. Could you also please suggest a source for scintillation crystals that could be used for gamma spectrometers that are not too pricey?
