Speed that Changes Decisions

NEMIS brings rapid, on-site microbial detection to the production environment, giving food safety teams actionable results while they can still do something about them.
With results in as little as 24 hours for Listeria and Salmonella and 16 hours for E. coli, NEMIS can help teams identify risks sooner, contain problems faster, and make corrective decisions without waiting days for an external laboratory.

How NEMIS N-Light™ Works

step-1

1. Preparation - Wet swab with buffer or neutralizer. Mark/label the swab tubes and the test tubes according to your test plan. Use N-Light™ MaxiSamplers for large or irregular surfaces

step-2

2. Sample - Swab a 10x10 cm area with firm pressure, rotating swab. Apply gentle pressure to penetrate biofilms.

step-3

3. Transfer - Open test tube. Add one starter tablet (Salmonella only). Break swab tip into enrichment broth and discard handle. Replace biosafety cap and push down firmly until you hear a click. Shake briefly.

steps-4b

4. Incubate - Place tube in NEMIS Dry Block Heater at temperature and time specified by IFU. Do not open tube during incubation. Do not use a standard microbiological incubator.

step-5

5. Activate - Release AquaSpark® tablet by pressing cap button. Verify tablet drops into liquid. Shake tube 5 seconds to dissolve. Return tube to heater at temperature and time specified by IFU.

step-6

6. Measure - Insert tube into NEMIS Bench Top Luminometer the IFU-specified minutes after tablet release (varies by test). Measurement takes 10 seconds. Results will be read as a presumptive positive or no detection of live target organism.
