Overcoming the challenges of environmental testing
Traditional environmental testing for Listeria is slow requiring enrichment and safety labs with results taking up to five days including transport. Delays mean storing finished products, driving up operational costs and increasing the risk of costly recalls if contamination is detected too late.
Imagine the impact on productivity and cost savings if results were available within hours.
testo Lab on a Chip is a revolutionary on-site microbiological testing solution that delivers rapid, accurate Listeria detection in just a few hours, not days, helping prevent costly recalls, reduce operational delays, and improve your food safety processes. No specialized lab. No complex preparation. No enrichment required.

testo Lab on a Chip is an advanced, on-site Listeria detection system that provides accurate microbiological test results in about four hours without requiring enrichment, a safety lab, or complex setup.
Analysis results are displayed on the device and can be send to the optional cloud software. Positive results can optionally trigger an e-mail alert.
testo Lab on a Chip is a high-performance, lab-quality solution built for high-volume testing in food manufacturing facilities.
testo Lab on a Chip is designed for flexible on-site Listeria detection, making it ideal for various environments and surfaces. It can be used for:
Daily Environmental Monitoring – Test surfaces, equipment, and workstations, such as stainless steel, conveyor belts, drains, walls, and packaging, to ensure ongoing hygiene compliance and prevent cross-contamination.
SOP Control & Remote Zone Monitoring – Verify that sanitation standard operating procedures are being followed in high-risk areas including hard-to-reach or remote locations.
Root Cause Analysis & Hot Spot Scouting – Quickly identify potential contamination sources by testing surfaces throughout the facility helping to pinpoint problem areas and take corrective action faster.
Quick Confirmatory Testing of Enriched Samples – Perform secondary testing to confirm preliminary pathogen presence, reducing the risk of false positives or unnecessary production shutdowns.
Currently, testo Lab on a Chip detects Listeria spp. We are working on identification of other common foodborne pathogens including Salmonella and E. coli.
Unlike culture-based testing, which can take 3-5 days, or PCR and ELISA methods, which require a lab and trained personnel, testo Lab on a Chip delivers fast, accurate results on-site within hours, reducing delays and improving food safety.
No. testo Lab on a Chip is designed for easy, on-site use without specialist staff, a dedicated lab, or extensive training.
By detecting pathogens faster, food manufacturers can take immediate corrective action before contamination spreads, preventing costly recalls and protecting brand reputation.
testo Lab on a Chip provides rapid, on-site pathogen detection, allowing food manufacturers to verify the effectiveness of their sanitation processes in near real time. By detecting only living organisms, it helps confirm whether cleaning procedures have successfully eliminated harmful Listeria spp. Unlike traditional methods that take days for results, testo Lab on a Chip delivers precise microbiological testing in hours, enabling immediate corrective actions if contamination is detected. This proactive approach reduces the risk of cross-contamination, ensures regulatory compliance, and enhances overall food safety.
Setup is easy. Just plug in and start testing. If you want alerts sent to your email, connect the device using a network cable or Wi-Fi.
While pricing varies based on usage, testo Lab on a Chip can reduce operational costs by eliminating the need for lab fees, enrichment steps, and storage delays, which saves companies money in the long run.

Faster, Smarter Pathogen Detection: The Future of Food Safety
For years, food manufacturers have relied on traditional pathogen testing methods like culture-based tests, PCR, ELISA, and lateral flow assays. These tests, while effective, have one major drawback — time. Culture-based testing can take three to five days for results including transport, requiring specialized enrichment steps in a certified safety lab. Even faster molecular methods like PCR and LAMP require trained personnel and expensive equipment. The result? Delays in production, costly recalls, and increased operational expenses from storing finished goods while waiting for test results.
