Don't need all the components in our standard kits? Or need extras of a few pieces? You can customize our kits here! We've done the hard work of going through the curriculum and figuring out what items are needed to complete each lab/activity (see 'Where Used' column). So just adjust the quantity of each component to fit your needs (FYI, the number included in the standard kit is shown by default). When you have the kit customized the way you want, just click the 'Add Selected Items' to cart button and continue your checkout.
