Lot of (50) Hamamatsu Photomultiplier Side-on Bialkali 931B Tubes + Sockets

Description

____________________________________
Hello, we're using these times to clean out some of our surplus equipment - these
Hamamatsu Photomultiplier Side-on Bialkali 931B tubes + sockets were removed from working devices that were being retired at the time.
This listing is for a lot of (50) tubes + sockets;
we have several hundred more of the 931B tubes
without the sockets included.  I'd be happy to make a bulk deal for all of the rest if you're interested (I can get a more accurate count of how many tubes are left if you'd like).
These are/were commonly listed at 0/tube - we're listing them for essentially scrap prices to clear them out.  So, while great efforts were taken to remove them carefully, they're being sold as-is.  A few may have cracks in the glass housing but the vast majority should arrive in perfect condition.
These will ship out within one business day upon receipt of payment and will be shipped via USPS Priority service to 'lower 48' US addresses only.  I'm sorry but we're not offering international shipping at this time - you may contact me if you'd like an exception to this.
We've sold quite a lot of our high-end surplus equipment on eBay over the years and have always maintained a 100% rating.
Please feel free to contact me by email with any questions or to inquire about international shipping.
