Description
Bacteria stain differently because they vary in cell-wall composition. This easy-to-use Gram stain kit allows you to view Gram-positive bacteria (blue) versus Gram-negative bacteria (pink) for bacteriological identification. Kit is designed with bacterial cultures that represent all 3 bacterial morphologies (rods, spheres, and spirals) so students can use classification to identify the bacteria. Requires the use of a microscope with an oil immersion lens (not included). Activity takes 45 min to complete. Kit includes detailed instructions and voucher to request shipment of perishable materials later at your convenience. Contact us or return voucher to request perishables.
