Argon Lecture Bottle Source: Matheson, Found Purity: >99.99% This lecture bottle was part of a popular series of lecture bottles 20-30 years ago. The bottle was found with no markings, but near a Matheson brochure. A quick call to Matheson revealed that dark green cylinders are indeed Argon cylinders. The cylinder does contain gas at high pressure, but I am unsure how full it is, as I found it. |
