Tryptic Soy Agar Ready-to-use Settle Plates (catalogue No. 146285) are pre-prepared irradiated culture plates based on TSA with lecithin, Tween and histidine (LTH) neutralizers. The 90 mm plates support microbial air monitoring and total aerobic microbial count determination on dry, sanitized surfaces and personnel in non-critical areas. This formulation facilitates cultivation of aerobic bacteria and suitability for pharmaceutical, environmental and general microbiology quality control.
Tryptic Soy Agar Ready-to-use Settle Plates, catalogue No. 146285, are pre-poured and irradiated culture plates supplied by Merck. The plates contain Tryptic Soy Agar with added lecithin, polysorbate (Tween) and histidine to neutralize residual disinfectants. These ready-to-use settle plates have a diameter of 90 mm and are designed for air monitoring and enumeration of aerobic microorganisms in quality control and environmental microbiology applications. The formulation supports a broad range of aerobic bacteria and simplifies routine microbial testing workflows.
