Portable Microbiology LIMS

A Microbiology LIMS That Fits in a Pocket

Leeuwenbook is a web and mobile application, named after Antonie van Leeuwenhoek, the "Father of Microbiology". It is the portable extension of CORPEX MicroLIMS, built for microbiologists who need to log samples, run tests, and pull a result without walking back to a fixed workstation every time.

It is aimed at labs and field teams that cannot centralize every test around one bench: water and environmental sampling crews, disaster-response and public-health units, and QC microbiologists who spend as much time on the plant floor as in the lab. Leeuwenbook covers growth promotion tests (GPT), microbial limits tests (MLT), test suitability, sterility tests, and antibiotic bioassay work, the same panels MicroLIMS runs at the bench, from a tablet or phone.

Portable LIMS Benefits

What moving microbiology testing off a fixed workstation actually changes.

Mobility & Accessibility

Carry essential testing tools anywhere. Enables testing in remote fields, disaster response units for on-the-spot diagnostics.

Rapid Response

Facilitates point-of-care testing for quick turnaround times, critical for effective disease control and patient management.

Real-time Data

Capture, analyze, and share data instantly across locations. Enhances collaboration among researchers and public health authorities.

Enhanced Efficiency

Streamlines workflows and reduces manual errors through automation and electronic data capture.

Cost-effectiveness

Reduces need for extensive infrastructure at every location. Saves on transportation and resource utilization.

EHR Integration

Integrates with Electronic Health Records so test results are available to healthcare providers without a separate data-entry step.

Media Preparation & GPT

Growth promotion testing (USP <61>/<62>) is routine but critical: a media batch cannot back a release test until its own GPT result is on file. Leeuwenbook records culture media preparation and the subculture of Certified Reference Microorganisms (CRMs) from a portable device, keeping that link intact even when the test is run away from the main lab.

Suitability Tests

Demonstrate that any residual antimicrobial properties have been neutralized before a sterility or MLT result is trusted. Leeuwenbook records the suitability method used against USP requirements, whether the sample was collected on-site or at the bench.

Microbial Limits Tests (MLT)

Assess viable microorganisms in non-sterile products under USP <61>/<62>. Leeuwenbook helps determine whether a sample complies with established specifications for microbiological quality, with the result logged the same way whether it came from a field sample or a bench sample.

Sterility Tests

Confirm sterile products do not contain viable microorganisms, under USP <71>. Leeuwenbook supports both sterility testing methods (membrane filtration or direct inoculation), crucial for medical devices and pharma products tested away from a central lab.

Antibiotic Bioassay

Estimate active constituents and biological activity of antibiotics. Microbiological assay helps in monitoring stability and resolving doubts regarding possible changes in potency.

How a Field Result Ends Up in the Record

The device changes; the path a result takes does not.

A microbiologist logs into Leeuwenbook on a tablet or phone and pulls up the sample against its specification, the same way they would at a fixed workstation. Media preparation and any Certified Reference Microorganism used are recorded before the test runs, and the GPT check for that media batch has to already be on file. The test itself, whether GPT, MLT, suitability, sterility, or bioassay, is entered directly into the record at the point of collection, with the reading time-stamped rather than written on a paper form to be typed up later.

Once connectivity is available, the result syncs back into the central LIMS and, where relevant, into the connected Electronic Health Record, so a clinician or plant QA reviewer sees the same record a lab-based colleague would produce. Nothing about the review step changes because the sample was collected off-site.

Why Portability Doesn't Relax the Requirement

A test run from a tablet still has to answer the same compendial and GMP expectations as one run at the bench.

Growth promotion testing under USP <61> and <62> still has to prove the media can detect the organisms it's meant to detect, whether that media was prepared at a central lab bench or logged from a field kit. Sterility testing under USP <71> still needs a documented test suitability study alongside the result, and microbial limits testing still has to show compliance against the same specification. Moving the interface to a tablet does not change what an inspector expects to see in the record.

What changes is where the record gets created. For water-quality crews sampling in the field, or a public-health team responding away from a fixed facility, that matters: results can be logged at the point of collection instead of being written on paper and re-keyed hours or days later, which is usually where transcription error and lost samples come from in the first place.

Leeuwenbook Alongside the Rest of the LIMS

Portable results still need to land in the same system as everything else.

Leeuwenbook is part of the CORPEX LIMS software family and runs on the same backbone as MicroLIMS, so a sterility or GPT result logged from a tablet in the field lines up with records kept at the bench, not a separate spreadsheet that has to be reconciled later. Environmental samples collected on-site feed the same trending logic used by Cleantrol EM, CORPEX's environmental monitoring software, and a result outside specification routes into deviation management the same way it would from the main lab.

Because Leeuwenbook is deployed as a GxP tool, not a convenience app, CORPEX scopes it under the same computer system validation package as the rest of the LIMS, so field data capture is validated, not just installed.

Leeuwenbook for Field Microbiology in Egypt

Egyptian water-quality programs, public-health teams, and food and pharma field sampling crews cover ground that a fixed lab workstation cannot always reach. Leeuwenbook lets that work stay inside the same Egyptian Drug Authority (EDA) GMP and EGAC ISO/IEC 17025 data-integrity expectations that apply back at the main lab, instead of falling back to a paper log that gets re-keyed later.

As a CORPEX product, Leeuwenbook ships with Arabic and English support and local implementation across Egypt. See our LIMS software for Egyptian laboratories page for how CORPEX scopes field and bench deployments together.

Leeuwenbook — Frequently Asked Questions

What is Leeuwenbook?

Leeuwenbook is CORPEX's portable microbiology LIMS, a web and mobile application that brings the power of a full LIMS to tablets and phones so microbiologists can track samples, run tests, and generate reports away from a fixed workstation.

Is Leeuwenbook a separate product from MicroLIMS?

No. Leeuwenbook is the portable extension of CORPEX MicroLIMS. It runs on the same underlying LIMS, so data captured on a tablet in the field lines up with the records kept at the bench.

What microbiology tests can Leeuwenbook run?

Leeuwenbook covers growth promotion tests (GPT), microbial limits tests (MLT), test suitability, sterility tests, and antibiotic bioassay work, the same core panels available in MicroLIMS, from a portable device.

Does Leeuwenbook integrate with electronic health records?

Yes. Leeuwenbook integrates with Electronic Health Records (EHR) so test results captured in the field are available to healthcare providers without a separate data entry step.

Where is Leeuwenbook used?

Leeuwenbook is built for point-of-care and field microbiology testing, including remote locations and disaster-response settings where a fixed lab workstation is not practical.

Is Leeuwenbook available for Egyptian microbiology labs?

Yes. As a CORPEX product, Leeuwenbook ships with Arabic and English support and local implementation across Egypt. See our LIMS software for Egyptian laboratories page.
