This special 50-well tube rack is designed to securely hold your 12 x 75 mm and 13 x 100 mm tubes in place using silicone tabs around each well. This makes it easier to empty contents before disposal and ensures stability during water bath use. Each position is labeled for easy identification, and racks can be connected together using screws included in the package.
