Media for the isolation and identification of microorganisms.

• Tubes are made of borosilicate glass
• Long-necked, rubber-lined screw caps prevent contamination
• Larger-sized tubes with wider diameters permit easy inoculation
• Securely fitted screw caps prevent loss of moisture

Media in Tubes are ideal for cultures requiring prolonged incubation, since the caps can be closed tightly to prevent dehydration and subsequent inhibition of growth. Caps contain a resilient rubber liner that resists displacement even during autoclaving.
