Eisco 100PK Scintillation Vials, 20mL - Borosilicate Glass - ASTM/USP Type I, Class B - Labs, CH0725P

I’ve knocked a few of these on the tile floor and they did not break. The bottom of one broke out when some praseodymium was off-gassing due to moisture in my mineral oil, but these faults do not lie in the vials themselves, just the operator.I’ve even used one in place of a test tube while reacting away the IC packaging from a silicon chip with nitric acid at 90 degrees C, as well as reacting the copper off of FMJ bullets to obtain a lead sample. The reaction is pretty violent and exothermic, but so far not a scratch.I have been collecting other compounds and allotropes, so I’ve used 90 of the 100 with a 1.111% failure rate.

This could be from a lack of understanding the type of cap, but there was no description of the material for the cap, so it was not easy to determine if the cap was able to go into an autoclave. It would also be important to know the thread size of the cap so new caps that are autoclavable can be ordered.
