Bellingham + Stanley Sodium Lamp Unit

Got this Bellingham + Stanley sodium lamp unit up for grabs. It's a specialized piece of lab gear, usually used for polarimeters or refractometers that need a specific light source. The blue casing is in decent shape and it has the standard power plug on the side. I haven't tested it recently so I'm selling it as-is, but these are built like tanks. Perfect if you're looking to complete a vintage lab setup or need parts for a BS refractometer.
