Prepared Microbiological Culture Media — Laboratory Grade

Microbiological culture media are nutrient formulations used by food, beverage, water, feed and industrial laboratories to grow, enumerate, select for or confirm micro-organisms. This is a product family page: media are supplied in several commercial formats — dehydrated powdered media, ready-poured prepared plates, bottled or tubed media and supplements — and the exact medium, formulation and format are selected per laboratory, not from a catalogue default.

Dehydrated media give the longest shelf life and the lowest cost per test but require preparation, sterilisation and in-house quality control. Prepared plates and bottled media remove that workload but carry a much shorter usable life and a cold-chain expectation. Which format is right depends on your throughput, staffing and storage, so state the format your laboratory is set up to run.

Media names in common use can correspond to more than one formulation, and accredited methods specify the formulation, the supplements and often the performance criteria. Send the method reference your laboratory works to so the request is made against that method rather than against a generic name.

For media used in released testing, the meaningful documentation is the lot-specific certificate covering growth promotion, selectivity and, where applicable, the reference strains used. Confirm what lot documentation is required before an order is placed, because it cannot be produced retrospectively.

Allzone does not publish a list of individual media, organisms, formulations or technical specifications on this page. Send the medium name, the method reference, the format and the quantity, and the specific item is sourced and quoted against that requirement.

Dehydrated media are kept sealed, dry and away from heat and light, with the container closed immediately after weighing, since moisture uptake degrades performance before it is visible. Prepared plates and bottled media are stored at the temperature stated in their documentation, protected from light and freezing, and used within the stated period. Confirm storage condition and usable life against the documentation issued for the exact lot supplied.

State the medium name and the method reference it must satisfy, the required format (dehydrated, prepared plates, bottled or tubed), any supplements required, the pack configuration your laboratory handles, the lot documentation you need, and your expected periodic usage.

Allzone Trading is a Canadian B2B sourcing and supply company. Exact grade, specification, packaging, origin, minimum order quantity, lead time, suitability for your application, pricing and supporting documents are confirmed during RFQ review and quotation. Nothing on this page should be read as an offer of a specific grade, potency, certification or availability. The workflow is RFQ, then Allzone customer specification review, then written customer approval, then quotation, then order.

Assay, particle size, solvent residue, microbiological limits and heavy-metal limits differ between producers and grades. Allzone confirms the applicable specification with the supplier before quoting and shares the technical data sheet, safety data sheet and certificate of analysis for the exact material offered, so the values you evaluate are the values you receive.
