Thermo Fisher Scientific has announced the global launch of Thermo Scientific™ InstaFlux™, an integrated media-on-demand enrichment workflow. The system is specifically designed to help food microbiology laboratories simplify media preparation and enhance sample traceability. By moving away from traditional batch-based preparation, the workflow aims to improve productivity for contract testing laboratories and food manufacturers.
Food testing laboratories face mounting pressure to process more samples and meet strict turnaround expectations. Concurrently, they must maintain consistent quality while managing staffing constraints and increasingly complex regulatory frameworks. The InstaFlux workflow directly targets these bottlenecks by enabling laboratories to prepare media on demand in under 30 minutes.
The automation shift in food testing laboratories
The demand for laboratory automation is growing rapidly across the food safety sector as managers seek to minimize human error and alleviate chronic staffing shortages. Industry analysts report steady growth in automated media preparation systems, driven largely by high-throughput testing demands. This transition mirrors other automation trends in the sector, such as the adoption of automated liquid handlers for serial dilutions, which reduce manual compounding errors.
Traditional media preparation is a notoriously resource-intensive and time-consuming process in food microbiology. Technicians must weigh dehydrated media powders, mix them with precise volumes of water, and sterilize the solution in an autoclave. Afterward, the media must cool to appropriate temperatures before it can be used for sample enrichment or poured into plates.
This batch-based approach forces lab managers to forecast their media needs well in advance. Forecasting often leads to overproduction and waste if testing volumes unexpectedly drop, or severe bottlenecks if pre-prepared media stocks are depleted during a sample surge. The InstaFlux workflow mitigates these scheduling headaches by shifting the paradigm from a 'make and store' model to 'make and use'.
"As food testing demands continue to grow, laboratories need solutions that help them do more with the resources they have," said Claribel Purcell, interim president of the microbiology business at Thermo Fisher Scientific. "Thermo Scientific InstaFlux reflects our commitment to helping customers modernize enrichment workflows through a simpler, on-demand approach that supports productivity, traceability and long-term operational sustainability."

Breaking down the InstaFlux media-on-demand workflow
InstaFlux combines concentrated sterile media, a sterile water supply, and automated gravimetric dispensing to streamline sample enrichment. It is particularly relevant for laboratories using buffered peptone water in routine workflows for organisms like Salmonella and Listeria. While downstream techniques like PCR, ELISA, or microscopy identify these pathogens, the accuracy of those methods relies entirely on proper initial sample enrichment.
The system supports gravimetric accuracy across 10 g to 125 g workflows, which complies with ISO 11133, ISO 6887-1, and ISO 7218 when validated by the laboratory. It brings several distinct operational capabilities to mid- and high-throughput laboratories:
- Media on demand: Reduces reliance on manual, batch-based preparation by producing enrichment media exactly when needed.
- Workflow efficiency: Decreases hands-on steps while supporting barcode-driven operations and digital audit trails.
- LIMS integration: Offers data-integration capabilities for compatible Laboratory Information Management Systems (LIMS).
- Validated performance: Ensures precise gravimetric dispensing that aligns with stringent international ISO standards.
Data integrity is a major focal point for modern food testing facilities, making digital audit trails a highly attractive feature for lab managers. The InstaFlux system supports digital records and barcode-driven workflows to track sample preparation precisely. When successfully integrated with a compatible LIMS, this level of traceability drastically simplifies compliance reporting.
These features directly address the strict record-keeping requirements mandated by modern safety regulations, such as the FDA's Food Safety Modernization Act (FSMA). Maintaining comprehensive traceability data helps ensure the safety of the food supply chain from raw agricultural commodities to finished products. The ability to easily retrieve this information simplifies audit preparation and ensures robust quality control across the organization.

How on-demand enrichment workflows solve operational bottlenecks
Moving to an on-demand media model fundamentally changes the resource consumption profile of a microbiology lab. According to Thermo Fisher Scientific, the InstaFlux workflow can reduce media prep labor by more than 80 percent. Furthermore, the system supports greater than 35 percent workflow cost savings, depending on the specific laboratory setup and testing volume.
Sustainability is another critical area where traditional batch preparation often falls short of modern corporate standards. Autoclaves are notoriously energy- and water-intensive, and conventional media requires substantial plastic packaging. The InstaFlux system aims to correct this, promising to lower water and energy consumption by up to 90 percent compared to conventional workflows.
Many food testing organizations are now mandated to meet strict corporate sustainability targets, making automated resource reduction a major selling point. By drastically cutting plastic waste and lowering utility consumption, automated systems like InstaFlux provide a measurable way for labs to achieve these environmental goals. This shift benefits both the organization's bottom line and its public environmental, social, and governance (ESG) reporting.
Environmental monitoring applications also stand to benefit significantly from this technology. Routine swabbing of food contact surfaces and facility environments generates highly variable sample loads that are difficult to predict on a daily basis. Having media available on demand allows quality managers to scale their environmental testing dynamically without worrying about media expiration or availability constraints.
| Workflow metric | Conventional batch preparation | Thermo Scientific InstaFlux |
| Preparation time | Hours (includes autoclaving and cooling) | Under 30 minutes |
| Media availability | Requires advance planning and storage | Prepared on demand |
| Labor burden | High (weighing, mixing, cleaning) | Reduced by over 80% |
| Water/energy use | High (autoclave dependent) | Reduced by up to 90% |
What this automated media preparation system means for your lab
For lab managers, the transition to automated media preparation represents a distinct opportunity to optimize physical footprint and labor utilization. The reduction in manual handling not only saves valuable technician time but also improves operator safety and lowers the risk of cross-contamination. Furthermore, standardizing workflows across different testing sites helps maintain consistent data quality for large contract testing networks.
Laboratories interested in evaluating the workflow must validate the system in accordance with their local regulatory and quality requirements. However, the long-term gains in operational flexibility and sustainability make it a compelling consideration for any facility struggling with throughput limitations.
