GEIGER TUBES: ADDITIONAL INFORMATION
Our Geiger tubes were produced in the 1950s we believe and are very delicate. The glass is inheriently thin creating a situation for damage to occur unless the most extreme measures are taken in handling and installation. Because we have no control over how you the experimenter will handle this product, no guarantee what-so-ever is implied or expressed as to the durability, function or use of this tube. You can be assured they are new and never used when shipped and since Halogen quenched tubes have a virtually unlimited life, if care is taken, you should have no problem constructing your own geiger counter.
