Chromogenic Culture Media Thailand — Liofilchem Chromatic Agar | BCST
Chromogenic Culture Media in Thailand — Identification by Color, Not Guesswork
Chromogenic culture media in Thailand, available through BCST as Liofilchem Chromatic Agar dehydrated media, transforms the way laboratories identify microorganisms. Traditional selective agars tell you whether an organism grew. Chromogenic media tell you what it is — directly from colony color on the primary isolation plate. Waiting for secondary biochemical confirmation is eliminated. There is no ambiguity in reading results. A single color reaction identifies the target organism after one incubation step.
This is the fundamental advantage of chromogenic technology. Specifically, the chromogenic substrate reacts with enzymes produced by target organisms. Each organism produces a characteristic enzymatic reaction. Consequently, that reaction yields a distinctive colony color directly on the primary plate. This saves time, reduces reagent costs, and accelerates the workflow from sample to result.
BCST distributes the Liofilchem Chromatic Agar range in Thailand as dehydrated media in 500g containers. Each container produces between 10 and 30 liters of prepared medium depending on the formulation. Consequently, the dehydrated format is the most cost-effective option for laboratories that prepare their own plates in-house.
Chromogenic Culture Media Thailand — Three Application Segments
Food Pathogen Detection Media
Chromatic Agar formulations for the detection and presumptive identification of major food safety pathogens — Salmonella, E. coli, E. coli O157, Vibrio spp., Cronobacter spp., Bacillus cereus, total coliforms, and broad-spectrum microorganism enumeration. These products support HACCP programs, ISO 22000 quality management systems, and food safety monitoring in compliance with Thai FDA and international food safety standards.
Additionally, individual formulations are validated against internationally recognized standard methods. These include EN ISO 6579-1 for Salmonella detection and ISO 22964:2017 for Cronobacter isolation. Consequently, they provide the documented validation credentials that accredited food safety testing programs require.
Full product details, specifications, and preparation data are available on the Food Pathogen Detection Media Thailand page.
Water Quality Detection Media
Chromatic Agar formulations for the microbiological monitoring of water quality — simultaneous detection of total coliforms and Escherichia coli from water samples using chromogenic and fluorogenic detection technology. Applicable to drinking water, process water, and wastewater monitoring programs under national and international water quality standards.
Furthermore, Chromatic EC X-GLUC Agar complies with UNICHIM M.U.1185 and APAT CNR IRSA 7030. These are validated methods for E. coli enumeration in water by membrane filtration. Both water quality media are available as dehydrated powder in 500g containers with a two-year shelf life.
All water quality media specifications and method details are available on the Water Quality Detection Media Thailand page.
Food Production Hygiene and Environmental Monitoring Media
Chromatic Agar formulations for the detection of hygiene-relevant organisms in food production environments — Staphylococcus aureus, MRSA, Candida spp., Group B Streptococcus, and ESBL-producing organisms. Applicable to environmental hygiene monitoring programs, food handler hygiene surveillance, food production surface monitoring, and microbiological quality assurance in food and analytical laboratories.
Complete product specifications and application guidance are available on the Food Production Hygiene and Environmental Monitoring Media Thailand page.
Why Chromogenic Culture Media in 500g Dehydrated Format
Ready-to-use plates offer convenience but carry significant cost and shelf life disadvantages for laboratories with established plate preparation workflows. Dehydrated media in 500g containers offer clear advantages for every laboratory that prepares its own plates in-house.
First, the shelf life of dehydrated Liofilchem Chromatic Agar is two to four years. This far exceeds the four to six months of ready-to-use plates. Second, the cost per prepared plate from dehydrated media is significantly lower at comparable quality. Third, dehydrated media gives the laboratory full control over preparation timing. Fresh plates are prepared on demand. Fourth, each 500g container produces multiple liters of prepared medium — supporting high-throughput laboratories running large plate volumes daily.
Consequently, dehydrated media is the preferred format for all established in-house microbiology laboratories in Thailand that test food, water, or environmental samples at volume.
Liofilchem — The Manufacturer
Liofilchem S.r.l. is an Italian manufacturer of culture media, antimicrobial susceptibility testing products, and microbiological diagnostic systems, established in 1983 in Roseto degli Abruzzi, Italy. Liofilchem produces its Chromatic Agar range to ISO 9001 quality management standards. Additionally, all products comply with ISO 11133:2014 — the international standard for preparation, production, storage, and performance testing of culture media used in microbiology.
Furthermore, individual Chromatic Agar products carry validation against internationally recognized standard methods. These include ISO 22964:2017 for Cronobacter and EN ISO 6579-1 for Salmonella. A Certificate of Analysis documenting lot-specific quality control testing accompanies each batch. Consequently, this provides the performance evidence that accredited laboratory programs and food safety audit frameworks require.
BCST is the authorized Liofilchem distributor in Thailand for food safety and analytical laboratory applications. All Liofilchem Chromatic Agar products available through BCST are supplied with full documentation — Certificate of Analysis, Safety Data Sheet, and Instructions for Use — at the time of order.
