Game-changing suite of detection tools

Sample to results in under 3 hours – empowering a proactive approach to quality at your brewery

brewLAP is the only detection tool for lactic-acid producing microbes with proven accuracy, unmatched ease of use and quantitative testing data available in less than 3 hours from sample collection – providing actionable results that enable you to optimize your quality processes.

Invisible Sentinel’s brew products are powered by Veriflow® - a game-changing platform technology that combines proven diagnostic principles for microbial detection and innovative, first-in-class scientific approaches. Veriflow technology offers unparalleled performance with no compromise in ease-of-use or affordability.

The Veriflow system is comprised of a small customized thermocycler, pre-aliquoted PCR reagent tubes, and proprietary buffers. Semi-quantitative test results are obtained in less than 3 hours via hand-held cassette, and quantitative results can be tracked, stored, and exported via the Veriflow Reader.

Speed, accuracy and sensitivity

Veriflow technology is AOAC International Certified for foodborne pathogen detection. The brew suite of products was developed specifically for the brewing industry and has been validated and implemented by a variety of award-winning, quality-centric breweries around the world.

  • Accurate, sensitive and specific to any lactic acid-producing Pediococcus and Lactobacillus species
  • Enables detection of microbes that can proliferate in low levels or absence of iso-alpha acids
  • Key applications include alcoholic and non-alcohol ciders and sodas

Simple and cost-efficient deployment

brewLAP is ideally suited for both high volume and craft brewers – with a modest capital investment and affordable per-test cost. Sample collection and prep is simple, and can be completed by brewing staff with minimal training.

  • Results in under 3 hours versus 3-4 days with traditional methods
  • Ideally suited for both high volume and craft brewers
  • Sample collection can be completed by brewery staff with minimal training

Ensure the integrity of your brand

The Veriflow system is ideally suited for onsite detection of spoilage organisms at any stage of production and in any style of beer.

  • Prevent processing, bottling, and shipping at risk
  • Allows traceability to the point of contamination
  • Reduces the risk of further contamination
  • Protects against recall of tainted beer

Benefits of using brewLAP

“Bringing brewPAL and brewLAP microbial detection system into our brewery is one of the best purchases we have made for our quality assurance testing program. The ability to detect lactic acid bacteria is very important to us in all of the beverages we produce, both alcoholic and non-alcoholic. Having data in a timely fashion allows for better decision making, resulting in improved quality, and less loss.”

Rebecca Brandenburg, Director of Quality The Lion Brewery, Inc.


Collect sample in a conical tube and centrifuge. Resuspend sample using provided proprietary Buffer A.

beer microbial testing


Transfer 5μl of resuspended sample into provided PCR reagent tube. Place tube into Thermocycler and run program.

beer testing equipment


Remove PCR reagent tube from Veriflow Thermocycler and add proprietary Buffer B. Dispense contents of tube onto test cassette window. Wait 3 minutes and retract test cassette switch to reveal test results. One line indicates negative result, two lines indicates semi-quantitative positive results.
