This product features 25mL of Tryptic Soy Broth (TSB) in a sterile tube, offering a "generous fill" format of the industry's most versatile liquid medium. Also known as Soybean-Casein Digest Medium, it is the primary choice for sterility testing, bioburden assessment, and general cultivation of aerobic bacteria, anaerobes, and fungi.The "Deep Fill" Utility: While standard tubes often contain 5mL or 10mL, the 25mL volume provides critical advantages for specific testing protocols:Sample Immersion: The increased depth of the liquid column allows for the complete immersion of larger items, such as longer medical devices, catheter segments, or bulky biological indicators (spore strips), ensuring no part of the sample is left exposed to air.Dilution Ratios: Perfect for maintaining specific dilution standards. For example, it can accommodate larger liquid sample additions (e.g., up to 2.5mL) while maintaining a 1:10 dilution ratio, or simply provide a larger buf
