Lab M (now part of Neogen) has long enjoyed an international reputation for the high quality of its dehydrated culture media, particularly for the culture and isolation of anaerobes.
The introduction of Harlequin chromogenic media and the company’s development of ISO compliant media formulations for food industry testing have confirmed Lab M’s leading position.
Lab M also supplies bulk peptones, extracts and other raw materials to pharmaceutical and large-scale fermentation industries, in compliance with current EDQM certification. Custom-designed and custom-blended products are also a specialty.
Lab M is certified in accordance with ISO 9001:2000 and ISO 13485; products for the clinical market are supplied in compliance with the European IVD directive and carry the CE mark.

Harlequin™ Chromogenic Media   Dehydrated Culture Media   Supplements & Additives   Captivate™
Chromogenic culture media provide a rapid and accurate method of isolating and enumerating target micro-organisms based on the detection of specific enzyme activities. Not only do chromogenic media enable faster detection of specific micro-organisms compared with classical culture media, they also improve sensitivity and can reduce the need for subculture or confirmatory tests. Lab M’s Harlequin range of chromogenic media includes products for the isolation of Listeria species, Salmonellae, Escherichia coli and Enterobacter (formerly Cronobacter) sakazakii.   Dehydrated microbiological culture media are fundamental to the day-to-day operation of most microbiology laboratories, delivering numerous benefits.
Convenient – use straight from the shelf – little need for refrigeration or specialist storage
Waste-free – make up only what you need, when you need it
Long shelf-life – years compared with days/weeks for ready prepared media
Specialist – the easiest way to add and control sensitive, non-autoclavable components
Cost-effective – fits all lab regimes and work loads
  We offer an extensive range of media supplements and additives to complement our dehydrated culture media product lines. Supplements and additives can be used to assist in the isolation, selection, enrichment or growth of micro-organisms.   Captivate™ is a range of antibody coated paramagnetic particles for the specific immunomagnetic separation (IMS) of microorganisms. Purified antibodies to surface components of the target microorganism are covalently coupled to paramagnetic particles. Careful antibody selection produces a highly specific system designed for microbiological immunomagnetic separation of target bacteria from enrichment culture. IMS increases the sensitivity of the methodology and, in most circumstances, results are achieved 24 hours earlier than using standard protocols. Offered as part of a standard range and as bespoke products, Captivate bacterial immunomagnetic separation can also serve as a capture system for rapid detection systems.
