These pre-poured 90mm plates offer a convenient, ready-to-use format that ensures consistent, high-quality results for diagnostic and research microbiology.
Features:
Enriched medium for cultivation of fastidious bacteria
Supports growth of Haemophilus, Neisseria, and other demanding species
Contains heated (lysed) horse blood providing X and V growth factors
Ready-to-use 90mm plates for reliable and convenient use
Supplied in packs of 10
Ideal for clinical, veterinary, and research laboratories
Storage Conditions:
