Designed for compatibility with rapid, on-site testing platforms, the N-Light™ MaxiSampler ensures reliable sample collection with minimal effort.
Sampling: A crucial part of environmental monitoring in food factories
Sampling in production rooms according to sampling plan
Sample transfer (time frame and temperature important!)
Sample analysis: On-site rapid test or at external laboratory
Data analysis decision on corrective actions planning of follow-up sampling
Why is the choice of the sampling device important?
The sampling device plays a pivotal role in the effectiveness of environmental monitoring. A carefully selected device ensures accurate and reliable sample collection by addressing key factors critical to the sampling process:
Force Application for Cell Removal:
The device must enable the application of sufficient force to dislodge even strongly attached microorganisms from surfaces, ensuring comprehensive sample collection.
Surface Area Coverage:
An optimized sampling device ensures that large or irregular surface areas are covered efficiently, minimizing missed zones and enhancing sampling accuracy.
Effectiveness and Capacity for Cell Pick-Up:
The design and material of the device, such as a flocked fiber coating, should maximize the adhesion of microorganisms, ensuring a higher yield of collected cells.
Minimized Cross-Contamination Risk:
A well-designed device reduces the risk of introducing contaminants during sampling, preserving the integrity of the collected sample.
Microorganism Viability During Transport:
The device must maintain the survival and/or growth of collected microorganisms during transportation to the testing site, ensuring the reliability of subsequent analyses.
Effective Cell Release into Testing Media
A high-quality sampling device facilitates the efficient transfer of collected microorganisms into a resuspension buffer or enrichment medium, ensuring that the sample is fully utilized in the testing process.

PREPARATION Repeat for 5-6 samples per reservoir and buffer tube
SAMPLING
Add the N-Light™ buffer to the sterile reservoir.
Mark/label the pouch according to your test plan. Open the sealed pouch.
Remove the N-Light™ Maxi-Sampler from the pouch and wet it in the buffer.
Store the wetted MaxiSampler again in its pouch and use it within 4 hours.
Sample surface areas of up to 0.3 m² by scraping the area in 3 directions with some force.
Place the N-Light™ Maxi-Sampler back into the pouch after sampling and proceed with step 3 within 4 hours.
TIPS:
Check full instruction
- For sampling wet surfaces, using dry MaxiSamplers is acceptable.
- Use the tip of the MaxiSampler swab to sample grooves and holes in the sampling area.
- Change the inclination of the handle during swabbing.

FAQs
The N-Light™ MaxiSampler is compatible with N-Light™ L. monocytogenes, N-Light™ Listeria spp., N-Light™ Salmonella Risk, and N-Light™ E. coli tests.
Swabbing with the MaxiSampler is as easy as with a normal swab. Wipe across the sampled area two to three times in different directions while inclining the handle to both side. Apply ample pressure to the surface with the robust handle, this helps to remove bacteria firmly attached to the surface.
If you sample dry surfaces, moistening the MaxiSampler with N-Light™ Neutralizer or N-Light™ BPW is essential. Wet surfaces can be sampled with the dry MaxiSampler.
Maximum 4 hours at room temperature.
The N-Light™ MaxiSampler can be used to sample surface areas up to 0.3 m² (e.g. 30×30 cm or 50 x 50 cm, making it ideal for sampling large surfaces for environmental monitoring.
It is best used for large, flat surfaces such as conyeyor belts, tables,carts, doors, plastic curtains, floors, machine covers and casings, walls, and countertops. It can be applied on all types of surface materials (stainless steel, plastic, ceramics).
Best is to place the MaxiSampler back in its pouch after sampling. Avoid touching the swab part with your hands or other sources of contamination. Then transfer the sample as soon as possible to the N-Light™ test tube.
Open cap of the test tube, then insert the swab part of the MaxiSampler in the tube with the tip pointing down, then turn the handle upwards to unlock the click mechanism, then let the swab part slip down into the test tube and screw the cap back on the tube.
Rising of the MaxiSampler surface with the enrichment broth in the N-Light™ test tubes is very important. By this, bacteria are washed to the bottom of the tube where growth in the right medium and at the right temperature takes place. For rinsing, move the closed N-Light™ tube in horizontal position, with the coated part of the MaxiSampler facing down. Then incline the tube upwards and downwards at least ten times, which will cause the liquid in the tube to flow back and forth over the fiber coating.
In case of N-Light™ Listeria spp. and N-Light™ Salmonella Risk tests, remove the MaxiSampler swab from the tube after rinsing. This is done by sticking the upper end of the disassembled handle into the upper end of the MaxiSampler swab inside the tube and then drawing the swab out. While doing this, leave as much enrichment broth as possible in the tube by sloughing off liquid from the swab at the tube wall. Discard handle and swab in a waste bin. Follow instructions for use of N-Light™ Listeria spp. and N-Light™ Salmonella Risk tests for further steps.
In case of N-Light™ Listeria monocytogenes and N-Light™ Escherichia coli, the swab part of the MaxiSampler is left in the test tube. Before starting incubation, don’t forget to press the cap of the N-Light™ test tubes down for locking the biosafety mechanism.
There is no need to reuse the MaxiSampler as each MaxiSampler comes with a swab attached to a handle.
