Three types of 96-well microtest plates are offered for general (non-tissue culture) applications including microbiology and serology. Available in U (round bottom), V (conical bottom) and flat bottom shapes. Each plate is individually wrapped to protect from air contaminants. Made from high optic transmission grade polystyrene, the microtest plates are arranged in a standard 12 x 8 configuration and have alpha-numeric position markings. Optional lids are also available. Both plates and lids may be purchased sterile or non-sterile.
