Benefits of the Oculer assays for microbial load assessment

Oculer’s TVC assays for assessing microbial load are fully automated and can be used at different temperatures and with different media according to customer requirements. A calibration curve is generated and stored on the instrument to allow simple and rapid estimations of microbial load during subsequent assays.

The counting range of the Oculer system is up to 10^7 cfu/ml removing the need for multiple dilutions. Use of the Oculer TVC assays negates the need for laborious counting of plates and interferences in colony counting due to sample particulates and spreading organisms. Bacteria are often found in clumps in many sample matrices and these clumps produce a single colony, thereby underestimating the microbial load. Oculer assays are not impacted by bacterial clumping because they measure the amount of microbial respiration.

How It Works

The Oculer Rapid 930 Series is a dual-function incubator/reader that, when combined with our bioengineered culture media and our precision oxygen depletion sensor forms a completely integrated package for food spoilage organisms.
