    If you’re making cosmetic products, a magnetic stirrer isn’t really necessary.

    If I were looking for any bells or whistles in a hot plate, it would be digital temperature control. You would find that a magnetic stirring bead would simply bind-up in the thicker viscosities of creams and lotions. You will likely be using an overhead lab stirrer instead.

    Thanks for the helpful responses @Perry @Microformulation

    I might end up a oidi g the magnetic stick then although I was planning on having digital temperature control.

    I find stir bars helpful when pre-making slurries and small amounts of solutions (dyes, pH adjusters, etc) but we have a LOT of hot plates around, if you’re only buying one then you should probably focus on other features.
