No mine is not a lab device, a standart deepfrezer..Also most of NoFrost refrigerators can reach to -24 celcius in their freezer section. it is enough to storage orchid seeds more than one year viable. But ideal storage is keeping inside liquid nitrogen tank (-196 celcius)

-80C freezer is also good for keeping plant material viable, but good luck getting one of those freezers!
