Prepare the paperwork. Reputable dealers will not sell to unlicensed artists and will ask for a business license, health certification or both to confirm.
Contact a reputable dealer (see Resources). These dealers will require the artist to fax or mail in their certifications to create an account. Many do not sell to the public.
Decide which equipment is necessary. If an artist is working for a shop, general and reusable equipment such as autoclaves, spray bottles, sanitizing equipment and other supplies may be provided.
Purchase the equipment. This can be done via the Internet, telephone or in person if the company has a storefront.
