Susceptibility and Identification Discs for Microbiology

Susceptibility and identification discs are impregnated paper discs used in disk-diffusion susceptibility testing and in biochemical organism identification. This category stocks antibiotic susceptibility discs across a wide range of agents and biochemical identification discs such as optochin, bacitracin and ONPG, packaged in cartridge dispensers and vials. Materials are supplied at wholesale case pricing for clinical, reference and research microbiology laboratories.

Disc Types Stocked

  • Antibiotic susceptibility discs - Discs impregnated with defined antibiotic concentrations for Kirby-Bauer disk-diffusion testing across a wide range of agents and drug classes.
  • Identification discs - Discs impregnated with biochemical reagents such as optochin, bacitracin, ONPG and X and V factors used to differentiate and identify organisms.
  • Beta-lactamase and enzyme discs - Discs used to detect specific enzymatic activity as part of identification and resistance screening.
  • Disc dispensers and cartridges - Cartridge dispensers and single-cartridge formats that place discs onto inoculated plates.

Widely stocked lines include BD BBL Sensi-Disc susceptibility discs, Thermo Fisher Oxoid discs and Hardy Diagnostics discs, supplied in cartridge dispensers and vials with matching dispensing hardware.

Storage and Cartridge Formats

Antibiotic discs are moisture-sensitive and carry defined refrigerated or frozen storage requirements to maintain drug content, so they are rotated by lot and expiration. Cartridge dispensers load into fixed-position dispensing hardware that places a set pattern of discs onto an inoculated plate, while single vials suit lower-volume or less common agents. Disc content, storage requirements and cartridge or vial packaging are listed per product.

Susceptibility and identification discs are a recurring microbiology consumable tied directly to isolate workup volume, and antibiotic discs carry short-dated storage that requires lot rotation, which makes case pricing and supply continuity important for laboratory procurement. Because discs are consumed with every susceptibility panel and identification workup, laboratories keep a working range in continuous inventory. MAP Medical supplies susceptibility and identification discs in case quantities for laboratory accounts. Order at the best Wholesale Prices with MAP Medical.


Frequently Asked Questions


What is the difference between susceptibility and identification discs?

Susceptibility discs are impregnated with defined antibiotic concentrations and used in disk-diffusion testing, where the zone of inhibition around the disc indicates how sensitive the isolate is to that drug. Identification discs are impregnated with biochemical reagents such as optochin, bacitracin or ONPG and help identify an organism by its reaction. Both are stocked here; susceptibility discs test resistance while identification discs support organism identification.

What is Kirby-Bauer disk diffusion?

Kirby-Bauer disk diffusion is a standardized susceptibility method in which antibiotic discs are placed on an inoculated agar plate and the diameter of the zone where growth is inhibited is measured after incubation. The zone size is interpreted against published breakpoints. Antibiotic susceptibility discs in this category are supplied at the defined drug concentrations used in this method, in cartridge dispensers and vials.

How are susceptibility discs packaged and dispensed?

Susceptibility discs are supplied in cartridge dispensers that load into fixed-position dispensing hardware to place a set pattern of discs onto an inoculated plate at once, and in single vials for lower-volume or less common agents. Cartridge formats speed routine panel setup, while vials suit supplemental agents. The packaging and matching dispenser format are listed per product.

Can microbiology labs order susceptibility discs in bulk?

Yes. Antibiotic susceptibility discs and identification discs are stocked in case quantities for hospital laboratories, reference and independent labs, clinical and research microbiology labs, and licensed distributors. Standing order programs account for the short-dated refrigerated or frozen storage of antibiotic discs with lot rotation so drug content stays valid. Contact our procurement team for tiered case pricing and standing order setup.

What discs should be included in a microbiology formulary?

A susceptibility and identification disc formulary typically includes the antibiotic discs matched to the lab's routine susceptibility panels and reporting requirements, the identification discs used for common differentiations such as optochin, bacitracin and ONPG, factor discs for fastidious organisms, and the cartridge dispensers that match the disc format. Composition follows the organisms worked up and the reporting menu. MAP Medical builds consolidated disc packages matched to lab volume - contact our team for an assessment.
