(qty 100) HAMAMATSU R6350 PHOTONICS PHOTOMULTIPLIER TUBE - INCREDIBLE LOT!

Description

13mm dia., Side-on type, Sb-Cs photocathode (Effective area : 4 x 13 mm/Spectral response range : 185 to 650 nm)
Acquired at a local auction of a lab's inventory.
Each tube is marked with what appears to be test results.  Kept in stock of local lab, perhaps each was tested and was to be used for specific purposes based on test specifications?
Unsure.
You are buying as-is.  The pins on ALL tubes are superb and clean.  Tubes have a label applied around glass, which should be removed by you (the end user).
No returns on these, I am assuming they are all ready to use, but again, acquired at auction - hence the very low price on this lot.
