A seed can provide a template on which additional macromolecules can assemble and under the proper conditions, grow to form a large single crystal. Using seeding can avoid problems associated with growing crystals from spontaneous nucleation. Seeds can grow into larger crystals in the metastable region of the solubility curve, which is a region of lower, relative supersaturation. One can also streak seed from phase separation or amorphous material as a diagnostic to confirm whether the material is crystalline.

The Seeding Tool is a 1 cm natural fiber attached to a stainless steel pin and plastic handle. The Seeding Tool is supplied with a cover to protect the fiber and when the cover is placed on the back side of the Seeding Tool, it makes an excellent handle.
