These quartz parting & annealing baskets for 9 samples are capable of withstanding:

Attack of concentrated nitric acid
High temperature necessary for annealing (up to 1000ºC)
Thermal shock due to very low coefficient of thermal expansion.
They are therefore suitable for simultaneously processing the two nitric acid attacks (the first with nitric acid 33%, the second with nitric acid 49%) and then go directly in the gold annealing furnace (after rincing with water).
