Carolina Biological Supply Co.

Once you hit middle and high school science, household supplies only go so far for labs. Carolina Biological Supply is a long-established science company that sells lab kits, microscopes, preserved specimens, and classroom materials to schools and homeschoolers. Founded by educators, it’s known for solid quality and detailed teacher guides, especially in biology and chemistry. Parents value that they can order dissecting specimens, microscope slides, or standards-aligned kits that feel like what students use in traditional schools. It’s ideal for families running serious lab courses or co-ops needing consumables. Shipping can be pricey, and some items have handling restrictions or require planning around live or perishable materials, but the reliability is high. Pro tip: bundle orders with friends or your co-op to share shipping costs and get the most value from bulk quantities.
