What Oculer does

Oculer Limited was an Irish private company that developed and commercialized the Oculer Rapid 930 Series, a fully automated benchtop incubator and reader for rapid microbiological quality testing in food, beverage, and pharmaceutical/cleanroom environments. The system uses a luminescent oxygen sensor to continuously measure oxygen depletion inside proprietary, gamma-irradiated, bar-coded APCheck vials prefilled with bioengineered selective culture media. As target microorganisms respire and consume oxygen, the fluorescent sensor reacts, enabling detection of growth without traditional plate counting. The platform supports an assay menu covering Total Viable Count, Yeast & Mould Detection, Commercial Sterility (CS-Check), Alicyclobacillus, Environmental Monitoring (EM-Check), and Gram Positive/Negative Screening, with reported sensitivity down to 1 cfu per 10 mL sample volume and results available 24-72 hours faster than conventional plate methods. Manufacturing of the instrument was outsourced to RTR Electronics Ltd in County Limerick, Ireland.

Oculer's business model combined upfront instrument sales (the 930-15 and 930-2 models, each handling 24 or 48 simultaneous tests respectively) with recurring consumable revenue from APCheck assay vials, supplemented by technical support services spanning needs analysis, in-house product testing, installation, on-site training, and ongoing QC program design. Pricing was quote-based with multi-year commercial packages structured to avoid large upfront capital expenditure for customers. Distribution was hybrid: direct sales in core regions complemented by selected distribution partners with industrial microbiology expertise in other geographies. The company served primarily food and beverage manufacturers, dairy processors, fruit juice and beverage producers, and pharmaceutical cleanroom operations in Ireland and the United Kingdom.

Oculer carried Microval and AOAC validations (formerly under the GreenLight trademark) and was pursuing BS EN ISO 9001:2015 QMS accreditation. As of the most recent source data, Oculer Limited is in Members Voluntary Liquidation, a solvent shareholder-initiated wind-down, and the operating business has effectively ceased. The founding directors and shareholders were Malcolm Bell (Chairman), Peter Thornton (CFO), Brian Byrne (CEO), and Prof. Colin Fricker (CSO and Head of Product Development).

Core offering

Oculer develops and sells the Oculer Rapid 930 Series, a fully automated benchtop incubator and reader that detects microbial growth by continuously measuring oxygen depletion within culture vials using a proprietary luminescent sensor. The platform is paired with a range of ready-to-use, gamma-irradiated assay kits (Total Viable Count, Yeast & Mould, Commercial Sterility, Alicyclobacillus, Environmental Monitoring, and Gram Positive/Negative Screening) and accompanying software for data traceability and LIMS integration, sold primarily to food and beverage manufacturers.

Product overview

Oculer offers a unified product ecosystem centered on the Oculer Rapid 930 Series benchtop incubator/reader combined with a range of proprietary assay kits and consumables. The core system uses luminescent oxygen sensor technology to detect microbial growth, with assays including Total Viable Count, Yeast & Mould Detection, Commercial Sterility (CS-Check), Gram Positive/Negative Screening, Alicyclobacillus, and Environmental Monitoring (EM-Check). All assays use pre-filled, gamma-irradiated APCheck vials with bar-coded traceability. The software platform provides integrated analytics with LIS/LIMS connectivity. The company was formerly marketed as GreenLight and continues to offer validated assays for food and beverage quality testing.
