Nanoracks’ Mixstix are mixture enclosure tubes for fluids, materials, chemicals and biological substances – all kept separate until they are ready to be mixed in space.
Single, double, or triple experiment sample segments are available. The experiments are activated by the astronaut crew. The crew releases the block on the chambers and shakes the tube to mix the materials. All Mixstix are 10 ml parylene coated silicon tubes. Mixstix can be stowed cold (+4°C), or ambient on launch, berth, pre/post operations, and on payload return to Earth.
