Hello Li, Have you tried a cassette made for 2" silicon wafers? They are still on the market and may work for you.

Does anyone know where we can buy sample holders/boxes that enable us to carry many 1" x 1" silicon samples? We prefer that samples can be stored vertically, but do not have to. Thank you in advance.
