Mueller-Hinton agar (MHA) plates are a defined, non-selective solid culture medium composed of beef infusion, casein hydrolysate, starch, and agar. This formulation supports uniform bacterial growth while allowing consistent diffusion of antimicrobial agents, making MHA agar the reference standard for antimicrobial susceptibility testing (AST) by disk diffusion, as mandated by CLSI and EUCAST.

MHA plates are commonly used to culture non-fastidious bacteria, including E. coli, S. aureus, P. aeruginosa, and other clinically relevant pathogens. We offer Mueller-Hinton agar plates in multiple formulations, including Mueller-Hinton II agar plates and other cation-adjusted formulations.

Our Mueller-Hinton agar (MHA) plates are supplied as ready-to-use pre-poured plates, eliminating in-house media preparation and reducing variability across testing workflows. Our MHA plates provide consistent agar depth, uniform growth, and reliable antibiotic diffusion, resulting in accurate and reproducible AST results.

We manufacture a variety of ready-to-ship MHA plates, including Mueller-Hinton II agar plates and various plate formats. All our agar products are manufactured using validated processes and undergo rigorous quality control testing to ensure growth performance and lot-to-lot consistency. Our team also offers custom manufacturing options, including supplemented formulations, alternative plate formats, and bulk quantities to support a wide variety of microbiology needs.
